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.
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, 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.
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 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 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.
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.
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.
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.
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.
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.

I use general hydro nutrients and have found that because the ppm of my water is below 50 I have to add small amounts of vsma and so to get the best results in my deep water system. A ppm meter is very important to a hydro system.
Hydroponic Seed Starting 101: A Primer for Beginners
Starting your seeds hydroponically has many benefits, but many people are unsure how to go about it. Shannon McKee gives us a primer on the basics of starting your own seeds to expand on what you’re currently growing.
Many people skip starting their own seeds because of the time and effort to get them started, but there are some great reasons to start your own seeds hydroponically. It’s so much easier to just go to the store to pick up some seedlings to pop into your system and get growing, right? Well, store-bought seedlings do have some downsides that can be avoided if you start your own.
The first is that you’re limited to what you can grow in your system. You have to choose from the options available at the store. However, if you start your own seeds, you can grow anything. This means you can grow your favorite heirlooms or even rare plants that aren’t found at many nurseries.
Adding seeds to your hydroponic system means that they won’t go through any trauma or root damage from being transplanted into your system. This process may also introduce diseases or bugs into your hydroponic system from the store.
Also, you get the satisfaction of growing a plant from a tiny seed rather than just picking up a seedling. Plus, a packet of seeds can grow a number of plants for just a few bucks, whereas the cost of only one seedling can be the same amount.
Seeds are also more cost-effective than buying one or two seedlings in the long run, as you can save some for the following year. The germination rate can decrease over time, but often, you can still get quite a few to sprout over the years until you have to buy your next seed packet.
What You Need to Start Seeds in a Hydroponic System
The first time you start your own seeds for your hydroponic system may be a bit more expensive at the beginning because you need to buy more materials than in future years. Seeds need water, light, oxygen, and heat to grow. You really don’t need anything too special to grow your own seeds.
You can use a grow tray with a dome for your own miniature greenhouse to create an ideal environment. If you’ll be growing your seeds in an area that is cooler, you may want to invest in a heating mat that goes underneath the grow tray to keep it warm as this is a necessary condition for sprouting to occur. Light is good to have as well as this will help your seeds sprout.
Inside of your grow tray, it can be beneficial to use a pot that works for your seeds and their future as seedlings in your hydroponic set-up. You’ll want to use starter cubes, such as those made of stonewool (rockwool). The key here is to use something that can withstand being immersed in water without dissolving, as it could clog up your system after transplanting.
Step by Step Instructions for Sprouting Seeds in a Hydroponic System
- The first thing that you’ll want to do is to soak your starter cubes in clean water for about an hour. After they’ve been given a chance to soak, put a few seeds into the cube’s hole. You’ll want to add several just in case you have some seeds that don’t germinate. Once they sprout, you can thin out the weaker plants to allow the strongest to grow.
- Prepare your grow tray with about an inch of clean water or nutrient solution that is at half strength. Arrange the light source and heating mat as needed. You can keep the lid on to keep the heat and moisture in the tray.
- Put these planted cubes into the grow tray and add water or the half strength nutrient solution as the level goes down in the grow tray.
- After about four days, you’ll start to see some sprouts emerging.
Some people prefer to use a Ziploc bag, rather than a grow tray, when trying to get the seeds to germinate as it functions like a greenhouse. Seal the bag with a little bit of air and put it in a dark place for about four days to get the seeds sprouted. Then, you can put the starter cubes with sprouted seeds into the grow tray.
Step by Step Instructions on Transplanting
Keep your tiny seedlings growing strong with your hydroponic nutrient solution. Once they’ve gotten bigger, you don’t have to make the nutrient solution half strength.
You’ll start to see the seedlings’ roots coming out of the bottom of the cube, and this is the sign you’ve been waiting for, as it means you can start transplanting. This can take about two to four weeks depending on what plants you’re growing.
Clear up a spot in your hydroponic system’s growing media for the seedling – cube and all. Gently transfer the starter cube into your growing media, and cover it gently.
Give the root system a chance to naturally seek out the water and nutrients in your system by top watering it for a few days to give it a chance to grow the root system.
Voila! You grew your own seedlings into a strong plant for your hydroponic system. Depending on the type of plant, you’ll be able to get your first harvest about four to eight weeks from the time you transplanted your seedlings.
Cut out the dependency of only being able to grow the types of plants that are available as seedlings at your favorite gardening store. Take a little extra time to nurture your seeds so that they become strong seedlings ready to transplant into your system. You’ll be able to take pride in your efforts with how healthy your plants are and your overall system’s health.
