How to Grow Cannabis Seeds Hydroponically

How To Grow Cannabis Seeds Hydroponically – Hydroponic cultivation is a promising solution to many challenges of crop production. It fixes the need for arable land, deforestation, ecosystem degradation, climate changes, and other issues related to cannabis cultivation. For decades, hydroponics has proven its effectiveness in various settings, and cannabis farming is no exception.

What Is Hydroponic Cultivation?

Hydroponics is a method of cultivating plants without soil by using mineral nutrient solutions in an aqueous solvent. In hydroponic cannabis cultivation, farmers plant their seeds in inert growing media and then supply them with nutrient-rich solutions like oxygen and water. To ensure that the plants remain healthy, farmers must control the whole environment, including nutrition, lighting, temperature, humidity, and oxygen. This system encourages rapid growth, high yields, and top-quality cannabis.

How to Grow Cannabis Seeds Hydroponically

To achieve successful results in hydroponic farming, cannabis growers must become acquainted with every component that ensures a smooth and efficient hydroponic grow. This includes selecting a grow medium, hydroponic system, lighting, nutrients, and more.

Choosing a Hydroponic Growing Medium

The first step to growing cannabis seeds hydroponically is to choose a growing medium. The medium allows roots to access nutrients in the water easily. There is an array of growing media to consider, but the right medium depends on which hydroponic system you will be using. Some of the most popular media include:

Clay pebbles

Clay pebbles, also known as hydroton, are great at aerating cannabis root zones. These particles have large pore spaces, allowing the nutrient solutions to flow through the medium easily. Their large pore size also reduces the chance of blockages within the hydroponic system. Clay pebbles are set up by simply placing them in the container and creating gaps for easy root penetration into the water.

Clay pebbles are a popular choice for small-scale growers; however, this type of medium might be too costly for larger operations. Another drawback is that farmers sometimes need to adjust the pH of the medium to provide an optimal growing environment.

Rockwool

Made using basalt rock and recycled slag, Rockwool is a type of mineral wool that is a popular medium for cannabis cultivation. Rockwool is excellent for water retention, allowing for adequate hydration of the upper root system. This medium also provides exceptional drainage, preventing the plants from becoming overwatered. Although Rockwool is a popular medium that offers many benefits, it is not environmentally friendly and requires pH adjustment for optimal plant growth.

Perlite

Perlite is a volcanic glass that expands when exposed to high temperatures. This medium is affordable and easy to use, making it a popular choice for hydroponic and soil growers alike. Perlite provides adequate aeration and prevents compaction in garden soil as well as hydroponics.

This medium does not degrade or decompose and can be reused multiple times before it starts to break into smaller pebbles. Perlite has a neutral pH and will take on the pH of the nutrient solution it is submerged in, making it easy for growers to regulate the acidity or alkalinity of their media.

Coco Coir

Coco coir is made from the hairy fiber on the outer shell of coconuts. This type of medium allows for proper aeration and moisture retention in hydroponic systems. It also protects roots from the harsh effects of plant-stimulating hormones. Coco coir is environmentally friendly, has a neutral pH, is reusable, and does not allow for the growth of fungi.

Choosing a Hydroponic Growing System

Most hydroponic systems are similar in their use of nutrient-rich water solutions; however, they differ depending on the material used, setup, water exposure, and circulation. Still, farmers can go for DIY systems using buckets, pumps, drills, and air stones. The best hydroponic systems to consider are:

Deep Water Culture (DWC)

Deepwater culture is a cheap and easy way for beginners to grow cannabis seeds hydroponically. To set up a DWC system, growers simply place their plants in buckets filled with nutrient-rich solutions and use air pumps to supply oxygen to the roots.

Because this system does not use a growing medium, it prevents pests from proliferating around the root zone. DWC systems are fully automated and require little maintenance to use, making them ideal for inexperienced growers or those with large-scale operations.

Ebb and Flow

This system consists of buckets hung over a growing tray with inlet and outlet waterways, both of which connect to an external tank. The tank periodically supplies the plants with fresh water that is rich in nutrients and oxygen. The system has a water pump and a timer to control the water cycle to and from the external tank and growing tray. Ebb and flow systems are ideal for beginners as these systems are highly effective, easy to use, and require minimal maintenance.

Nutrient Film Technique (NFT)

With the nutrient film technique, plants absorb nutrients and oxygen from a solution that flows through growing trays. The tube that circulates the solution is tilted slightly to allow the water to flow from one side of the reservoir to the other. With this system, crops receive a constant flow of nutrients and oxygen. Growers can conserve water and nutrients by using the nutrient film technique because the nutrient solution is constantly being recirculated.

Drip System

A drip system is a type of irrigation method that slowly drips nutrients and water into the roots of the cannabis plants. This system consists of a large tray with a growing medium such as clay pebbles or perlite. Cannabis plants access the constantly flowing solution through individual pipes, and the excess solution drips down the growing medium and back into the reservoir. Because drip systems slowly release water to the plants, it reduces the amount of water lost due to evaporation. This system is also very energy efficient, as it does not require a great deal of pressure from a powerful pump.

Wick System

Much like drip systems, wick systems use growing trays that are filled with clay pebbles. A water tank rests underneath the tray from which several wicks connect to the medium. The solution travels down the wicks, passively hydrating the roots of the plants. This type of system is entirely passive and does not require any pumps or air stones. Wick systems allow the plants to access only as much water as they need, meaning that growers need not worry about overwatering their crops.

Aeroponics

In aeroponic systems, plants are suspended inside of a chamber, and their roots are misted with water. Aeroponic systems are often used to start clones but can also be used throughout the entire growth cycle. This type of system may not be ideal for inexperienced growers, as it takes some expertise to set up and maintain. This system also makes it easy for pests and diseases to take hold in the garden.

Choosing Lighting

In the past, most farmers preferred to use high-intensity discharge lights (HIDs) such as high-pressure sodium (HPS) or metal halide (MH) lights. But the recent full spectrum light-emitting diode (LED) grow lights have had tremendous success.

MH lights are close to natural lighting and are abundant in blue and green spectrums, which are best for vegetative growth. HPS offers orange, amber, and red-light spectrums, which are best for later cannabis flowering stages. Farmers often use metal halide lights during the vegetative growth period and switch to high-pressure sodium lights during the flowering period.

Although HID lamps provide an excellent light source for plant growth, they waste lots of energy and produce excessive heat. To mitigate the heat, farmers should invest in robust ventilation systems, including can fans and oscillating fans.

Lately, many growers have started using full-spectrum LED lights, which are far more energy-efficient than HID ones. Moreover, they are perfect for all growing phases and don’t require a ballast to power them.

Because most strains of cannabis are photoperiod-dependent, farmers should carefully regulate the light cycle during the vegetative and flowering stages. This is a crucial step in growing cannabis seeds hydroponically.

Nutrients

Like other crops, cannabis requires an abundance of major nutrients, including nitrogen, phosphorus, and potassium. Additionally, it requires smaller amounts of other nutrients such as boron, sulfur, calcium, magnesium. The best way to feed cannabis plants is to use hydroponic nutrient solutions containing all the required nutrients for the vegetation and flowering periods.

What is hydroponic weed?

Hydroponics for weed is simply farming cannabis without the use of soil. All you need for plants to thrive is water, warmth, and air. Hydroponic cultivation has been in existence for thousands of years, even though many people regard it as a new concept.

One of the earliest records of hydro traces back to the famous hanging gardens of Babylon in 600 BC. Cultivators installed a chain system that pulled water from the Euphrates River and trickled it down into the grounds.

The floating gardens of China recorded by Marco Polo in the 13th century is another example of early hydroponics. Rafts made out of reeds and topped off with a bit of soil floated out to the water. Aztecs also used hydro techniques in the 10th and 11th centuries.

Weed hydroponics is nowadays the go-to method for commercial cultivators and city dwellers worldwide. Microorganisms in soil break down organic compounds to provide nutrients to the plant. Hydroponic mediums are inert, meaning they do not participate in any growing activities. Add fertilizer that’s required to water during each feeding.

Hydroponic weed vs. soil

Deciding between hydroponic weed vs. soil is a case of convenience and personal preference. Here are the advantages and disadvantages of a hydro setup.

Pros

  • Cultivars in a hydroponic weed setup have a higher growth rate because the roots don’t spend energy searching for nutrients.
  • Faster growth leads to shorter farming cycles, meaning more return and increased output.
  • Cultivate in a smaller space.
  • Total control of the growing process for healthier plants, consistent results, and scaling up operations.
  • Hydroponic grow systems for weed are less prone to bug and pest infestation.
  • Clean, since you don’t get dirty, unlike when handling soil.
  • There is no need for crop rotation due to infertile soil.
  • Groundwater is less likely to be contaminated.
  • Less demand for fresh water. Saves up to 80%. Ideal for commercial cultivators in water-scarce regions.
  • Propagate out of season in a controlled environment.

Cons

  • Higher initial costs.
  • Hydroponics marijuana cultivation is less forgiving than soil. It is important to correct any pH problems as soon as possible and closely monitor the nutrient levels.
  • Brings a potential risk of harder to deal with water-borne plant diseases.
  • Requires knowledge and patience
  • Roots are susceptible to damage if there’s a pump failure or you run out of water.

Is hydroponic weed stronger?

This debate has run for decades. Even though most people believe hydro weed buds are more potent, no scientific analysis supports this. A study conducted in 2013 didn’t find significant differences in THC levels of 26 samples of crops seized in Australia by NSW police across the state.

Master grower Kyle Kushman recommends cultivating marijuana in soil to give buds a unique terpene profile for a more complex flavor. Many cannabis connoisseurs say hydroponic buds have a strong, chemical-like smell and taste if the plants are not flushed close to harvesting.

A study conducted by D.R. Hoagland and D.I. Aron in 1950 shows that hydro doesn’t produce higher yields than soil. However, expect to harvest hydroponic weed buds faster since plants absorb food more quickly, and roots have easier access to oxygen.

What do you need for a hydroponic system for weed?

Setting up a hydroponic system for weed may initially appear expensive, but the subsequent costs are manageable. Hydro farming is best left to experienced cultivators because plants won’t do well if a mistake happens.

Here’s how to create the right nutrient solutions and environment for hydroponics cannabis to thrive.

Different mediums for hydro weed

Cultivate hydroponic weed in many setups since all you need is a nutrient-laden solution, warmth, and air.

Examples of alternative inert growing mediums include; coco peat, pumice (volcanic rock), clay pebbles, sand, gravel, Rockwool, perlite, granite, ballast, or brick shards. A DWC hydroponic weed grow system has water as its primary medium.

Treated and stabilized coconut husks chips make coco peat/coir. This common hydroponic medium retains water suitably and resists fungal growth.

Rockwool is another popular medium because it holds water and air well enough. However, it may require some balancing because it could have high pH content.

Clay has tiny holes that hold nutrients and air, but roots of hydroponic weed growing in it often become tangled by harvest time. Recycle this material after sterilization by soaking it in water and hydrogen peroxide.

Perlite comes from volcanic glass or sand, so it doesn’t hold onto air or nutrients sufficiently. Growers mix vermiculite and perlite to increase water retention. Construction-grade vermiculite, however, could contain toxins.

Check out our hydroponic growing medium page for more details.

What hydro nutrients should you use for cannabis?

Plants need suitable nutrients, so you have to apply the right solution when required. Plants grow healthier and faster in hydro because you give them what’s required.

Formulate nutrient solutions for hydroponic cannabis using chemicals or buy them pre-mixed. Excess nutrients could overwhelm and damage the plant due to lockouts, while too little stunts growth.

Water for a marijuana hydroponic system needs to have macro and micronutrients. The main macronutrients are nitrogen (N), phosphorus (P), and potassium (K), usually denoted as NPK in fertilizer solutions, with varying ratios.

Non-distilled tap water has the majority, if not all, of the micronutrients required in minute quantities. Plants need nitrogen in higher concentrations for vegetative growth, whereas phosphorus and potassium are necessary for blooming.

Nutrient mixes come with a feed chart to guide you on the concentrations required. Check out our hydroponic grow schedule for more on this. Optimal NPK ratios at different life cycles of hydroponic weed cultivars are as follows:

Growth stage N P K
Seedling 2 1 2
Early veg 4 2 3
Advanced vegetative 10 5 7
Veg to flowering transition 7 7 7
Early flowering 5 10 7
Full Flowering 6 15 10
Final flowering 4 10 7

Always start with pure water and work your way up. Replace your nutrient solution if you notice your plants starting to yellow or brown and get crispy because they might have a low mineral content.

Use an EC or TDS meter to determine the concentration of nutrients in your reservoir. TDS stands for total dissolved solids indicated in parts per million (PPM), while EC means electrical conductivity.

The ideal PPM range for each phase of the hydroponic marijuana plants’ life cycle is as follows:

Stage PPM
seedling 100–250
clones/ early veg 500–600
Late veg 800–900
flowering 1000–1100

Can you use any water for hydroponic marijuana?

No, you can’t because the water for hydroponic cannabis needs to have an ideal temperature, pH, and PPM levels.

Pure water is always the best base to start with, and then add nutrients as needed in the right balance and concentration. Distilled or stormwater usually has a neutral pH and a low PPM—ideal for starting weed hydroponics. Minerals, chemicals, and impurities change nutrient levels and pH.

Tap water found in urban cities often contains chlorine to kill bacteria, but this chemical is detrimental to plants. Let it dissipate by exposing the water in your reservoir for a day or two. Accelerate this process by using air stones.

Many rural regions have hard water from wells because it contains heavy minerals like calcium. Purify it using carbon-based or reverse osmosis filters to remove all the excess minerals and impurities.

You should not recycle the nutrient solution in a weed hydroponics reservoir for more than two weeks. Add beneficial additives like hydro guard into the reservoir to fight off bacteria that cause root rot.

Keep a sterile environment when growing weed in a hydroponic setup. Wipe your equipment with alcohol, hot water, and peroxide before getting started. Wear sterile shoes and clothes to avoid contaminating your grow room.

What is the optimal hydro weed pH range?

pH is a measurement from 0 to 14 that shows whether a solution is acidic or basic, respectively. pH for cannabis determines how well your cultivar absorbs nutrients.

Marijuana plants absorb required nutrients in a slightly acidic environment. Optimal water pH in a hydroponic weed setup is between 5.5 to 6.5, while soil ranges from 6.0 to 7.0.

Stay on top of pH daily because it’s often a problem if you have enough fertilizer in water, yet your plant looks deficient of a particular nutrient.

It’s better to get a litmus paper than a cheap digital pH meter that gives wrong results in pH tests. Cultivators normally use “pH up” and “pH down” to correct pH as required. Adjust pH after adding nutrient solutions, not before.

How do you provide oxygen to hydroponic cannabis roots?

Plants take in carbon dioxide (CO2) through their leaves and oxygen (O2) via their roots.

Each hydroponic weed system has a way of providing oxygen to the cannabis roots. For example, a deep water culture setup administers the gas to a nutrient solution using air stones inside the reservoir. Most of the oxygen dissolves in water due to bubbles that create ripples.

Dissolved oxygen (DO) prevents the growth of anaerobic bacteria that cause root rot for plants or diarrhea, nausea, cramps, or headaches for humans. A high concentration of DO promotes rapid root growth, enhancing the plant’s ability to absorb nutrients.

A flood and drain hydro weed system has a wet to dry cycle, allowing the roots to breathe most of the time. Ensure the water in your reservoir stays within the 64 to 72 ℉ range to hold dissolved oxygen better.

What kind of grow lights should you use?

Artificial lighting is necessary if cultivating plants indoors. Marijuana needs enough of the right spectrum for each growth stage. Blue light for veg and red for flowering.

Expect to harvest around 0.5 to 1 gram per watt. For example, a 600w HPS lamp should produce 10 to 21 ounces of bud. Hydroponic weed plants grow fast, so keep an eye on the heat coming from your apparatus to avoid potential light burn.

Apply a hand test above the canopy when in doubt and observe if it starts to heat up. Move your lights further away if the temperature is too high.

HID (MH + HPS) is usually too powerful for newly sprouted seedlings, so it’s best to use a CFL or an LED light with a dimmer at this stage.

Metal halide (MH) gives off a blue spectrum that promotes the growth of stems and leaves during the vegetative period. High-pressure sodium (HPS) bulbs emit a yellowish glow, ideal for flowering hydroponic cannabis plants.

LED grow lights are the choice option for the modern marijuana cultivator. They run cooler than HID lamps, are easy to install, and some provide the full spectrum of colors needed during the vegetative and flowering phases.

Here’s a comprehensive guide on choosing the best grow lights for indoor plants.

At what temperature range does cannabis thrive?

Many cultivators have a challenge maintaining the right water and room temperature for growing weed.

Hydroponic weed plants thrive in an environment that’s between 73 and 80℉. A climate cooler than 60℉ slows growth and could even shock your plants resulting in zero yields. Frosty conditions also lead to too much moisture/humidity in your grow room, encouraging mold to flourish.

Extremely high temperatures stunts growth, producing loose or airy weed buds that are not as potent or aromatic as you’d like. Some pests like spider mites thrive if temperatures are above 80 ℉. Invest in thermometers and place them strategically to ensure the grow room doesn’t have hot or cold spots.

Remember to keep the water in your reservoir at around 68℉ for better oxygen retention. Buy a water thermometer to track this.

What is the best humidity level for marijuana in hydro?

The relative humidity (RH) of your hydroponic weed grow room should be around 60% when starting. Seedlings primarily rely on moisture from the air to survive since they don’t have sufficient roots. Most cultivators place a dome on top of their seedlings to maintain dampness.

Work the RH down from 60 to around 50 when flowering and 40 by harvest time. Here are the recommended cannabis humidity levels across the plants’ life cycle:

Stage Humidity level
clone / seedling 70%
vegetative 40–60%
flowering 40–50%
final two weeks 40–45%

Lowering humidity as your plants get bigger encourages stronger root growth and reduces the chances of bud rot from mold and mildew. Gradually drop the RH by 5% per week to avoid stressing your hydroponic cannabis plant.

Measure moisture levels using a hydrometer. Invest in a humidifier and dehumidifier to maintain ideal humidity in your grow room.

How do you circulate air in the grow room?

Mitigate the effect of heat produced by certain lights such as HID by adding oscillating fans to your grow room. Propellers expel warm air and draw in fresh, cool air.

The breeze from oscillating fans also ensures the branches and stems are stronger. It’s better to strategically place smaller fans in your hydro weed grow room instead of one large ventilator. Air circulation reduces humidity, lowering the risk of attracting powdery mildew, fungus gnats, and spider mites.

How to grow hydroponic weed

Several hydroponic grow systems for weed exist, with varying levels of complexity. Here are some of the most popular setups.

Deep water culture (DWC): Beginner

DWC is the easiest active hydroponic weed system to set up. All you need is a reliable power source, basin, grow medium, and net pots to hold the plant in place with roots immersed in an aerated nutrient solution. Air stones supply air and oxygen to the water.

Net pots filled with an inert growing medium secure the plant above the reservoir. Do your best to maintain the same water level throughout the grow.

DWC hydroponics for weed requires little effort to operate, but the air stones must run constantly. Roots start to suffocate if the air pump goes off for more than 20 minutes. Find out all you need to know about a deep water culture system.

Wick system: Beginner

This passive marijuana hydroponic setup utilizes wicks made of absorbent cotton, cloth, yarn, or medium. This technique is cheap and easy to set up since there are no moving parts.

A wick system doesn’t make any noise and is ideal for a stealth hydroponic grow box. Control water flow rate by shifting the position of the reservoir or adding extra wicks to draw nutrients.

Ebb and flow/flood and drain: Beginner

The ebb and flow system floods the plant’s roots with the nutrient solution from the bottom up periodically instead of traditional watering from the top down. A wet to dry cycle exposes the roots to air in between saturation. This hydroponic marijuana system requires a timer to operate and more equipment to put together.

Drip or top feed: Intermediate

Drip systems are more common in soil cultivation, though they work just as well with inert growing mediums. Water any type of hydro weed medium as frequently as needed in a drip system. The nutrient solution drips into the pot, and excess is recycled.

Aeroponics: Intermediate

Roots are suspended in the air and frequently sprayed with a nutrient solution in this active hydroponic system for weed. Expect rapid growth, especially in the early stages of the plant’s life cycle. Aeroponics is popular for propagating clones and nurturing seedlings until they are ready for the vegetative stage.

Unfortunately, the spray nozzles are static, so they can’t deliver much nutrition when the plant root ball becomes too large. Also, the high cost to build and risks involved with equipment failure makes aeroponics unideal for the entire life cycle of the hydroponic weed plant.

Nutrient film technique (NFT): Advanced

NFT for hydroponics cannabis has roots growing inside a large angled tube with nutrient-rich water running through it. Adding more plants is a simple matter of expanding the tube length. Recycle excess nutrient solution that flows into a reservoir. Keen observation of this system is key because roots could fill the pipe and restrict water flow.

NFT can be costly, complex to set up, and requires a large area to operate. The system is popular among commercial cultivators since it allows them to grow many plants easily and with little maintenance.

5 best strains for hydroponic cannabis

Not all strains work well in a marijuana hydroponic setup. You have to consider the size the plant grows to and how large your reservoir should be. pH fluctuations are more common in a hydroponic system because there’s no buffering from soil.

Here are five strains with ideal sizes that withstand variance in pH better than others.

Amnesia Haze

Amnesia Haze feminized is a multi-award-winning strain renowned for its energizing, uplifting effects and citrusy, earthy flavors. Contrary to its name, Amnesia Haze is great for daytime activities where you need to be alert.

This strain doesn’t expand to a massive size despite being a sativa dominant strain. It grows to a medium height (3–3.5 ft) that’s more manageable in a weed hydroponics grow room. Expect an outstanding indoor yield of up to 28 oz./m 2 after around nine weeks of flowering.

Gorilla Glue (GG)

Gorilla Glue #4 feminized has a legendary status because of its high THC level (26–28%). Its relaxing effect releases tension, extinguishes stress, and induces a meditative state. Its buds make hash heads go crazy because it oozes sticky resin from top to bottom, hence its name.

The GG has a delightful coffee-like taste that lingers on the palate. This perfectly balanced hybrid grows to heights of up to 6.5 ft and delivers colossal yields of 16–19 oz./m 2 indoors. Expect this super strain to finish flowering in 8 to 9 weeks inside a hydroponic system for weed.

Northern Lights

There’s no need to brave the cold arctic to witness the Aurora Borealis when you can feel it in your mind. Northern Lights feminized is an indica dominant strain that’s probably the first high-grade cannabis most consumers encounter. Why? It’s easy to grow and delivers a potent, soothing effect that melts your muscles and diffuses tension. Immerse yourself in the moment and detach from the outside world for a blissful starry night.

Northern Lights gooey buds have a delicious, sweet, and fruity flavor. It grows to a moderate height of just 3–5 ft, great for a small reservoir and space in most weed hydroponics systems. Expect massive indoor yields of up to 18 oz./m 2 after an incredibly short 6–8 week flowering period.

White Widow

The White Widow Feminized is a popular high-grade hybrid that stimulates creative and focused thinking during an outing. White Widow is so named because her buds are smothered in a thick sugar glaze when she flowers. A top pick for hash makers.

White Widow produces impressive yields of up to 16 oz./m 2 in an indoor hydroponic marijuana setup. She grows steadily and finishes blooming in just 8 to 9 weeks.

Skunk

Skunk feminized is another classic marijuana strain that’s a huge favorite among commercial cultivators. It’s easy to propagate, grows to medium size, and produces massive yields of up to 16 oz./m 2 in an indoor hydro weed setting. This multi Cannabis Cup award winner finishes flowering in just 8–10 weeks.

Everyone loves its fruity taste and powerful stress dissolving effects that brighten up your soul. Demanding veteran consumers love Skunks’ gripping effects.

That hydro’s got my eyes low

You’ll never want to go back to soil once you grow hydroponic weed. Choose a system based on your budget and level of experience. Start with a beginner-friendly concept like DWC before venturing to more complex setups.

Monitor your nutrient solution (pH and PPM), temperature, humidity, ensure adequate air circulation and pick the right light for each stage. It might seem difficult to manage these variables, but it becomes easier with experience.

We also have perfectly balanced nutrient solutions tailored to hydro weed plants during each growth stage, in addition to an astronomical collection of premium marijuana seeds. Don’t miss out on either.

Growing Hydroponic Feminized Cannabis Seeds

Growing hydroponic feminized seeds can produce amazing results for cannabis growers. Hydroponics growing methods can produce super fast growth rates, high yields and super clean potent buds. Cannabis thrives in hydroponics, where roots have more access to oxygen, water and nutrients round the clock versus conventional growing methods. A lot of bud farmers greatly reduce veg times by growing in hydroponics; still harvesting very large budded plants for the same flowering times; hydroponics can hypercharge your crops.

Just like there are a lot of great female seed strains to choose from, there are a lot of different types of hydroponic growing methods and systems that you can use. Fact is some are better suited to growing feminized seed strains than others–that’s because female seed plants develop a solid tap root; something cloned plants never have.

Restricting the tap root of a female cannabis seed strain puts a lot of stress on the genetics–just like with conventional feminized seed growing tips HERE. It’s best to avoid putting hard stresses on ANY feminized seed plant, or growers may trigger undesirable traits, including pollination in severe instances.

What are the Best Hydroponic Systems for Growing Female Seeds?

Typically hydro set ups with more space for the root system is best–DWC (deep water culture), RDWC (recirculating deep water culture), large coco pots and similar are ideal. These types of systems have plenty of room for tap roots to stretch out and support large healthy root systems. They are also very productive and save on water and labor.

What are Hydroponic Systems to Avoid to Grow Female Cannabis Seeds?

Smaller sized grow blocks, like rockwool or small pots filled with grow rocks, etc will restrict root development, creating stress on feminized cannabis seed genetics. A 6 inch cube or pot should be considered the bare minimum, provided that plants will be flowered not long after seedlings are established. Larger is recommended.

What are Other Important Things to Avoid with Hydroponic Female Seed Plants?

Avoid wide drifts or big ups and downs with EC/TDS, pH and temperature in the root zone or nutrient solution. In bigger water culture set ups or hydro systems growers may use reservoir chillers during hotter times or may require submersible aquarium type heaters during cooler months. Try and keep roots at a steady 65 to 75 deg F. Wide or frequent swings can put a lot of stress on certain strains and cannabis varieties, with some being more root sensitive than others.
