How to grow hydroponic weed?

Cannabis is a hardy plant that can adapt very well to different conditions so that it can be easily grown on almost all plant substrates. The most common methods are growing in soil or in hydroponic systems with substrates such as rock wool, coconut, expanded clay or Mapito.

Due to the benefits of using a hydroponic system, growing hydroponic weed has become very popular. However, to novice growers, it may sound off-puttingly technical.

No worries, we tell you exactly how to grow hydroponic weed including the best hydro systems and nutrients.

What is hydroponic weed?

Hydroponic is one of the most used methods of growing cannabis and is a very old cultivation method – archaeologists believe that hydroponics was used in the Hanging Gardens of Babylon. There are several types of hydroponic systems, but all are based on the same principle. The idea is simple; it is based on making the nutrients available to the plants by quickly absorbing fertilisers in an inert substrate such as rock wool, expanded clay or Mapito.

How it works

By using an automatic irrigation system, either recirculating (the nutrient solution is reused) or waste-to-drain (the excess nutrient solution is not reused), the cannabis plants are optimally supplied with nutrients. When using expanded clay, it is imperative to stabilise the pH of the substrate to avoid problems with the pH during the grow. If the expanded clay is not stabilised, many difficulties arise for the plants, and they will not be able to absorb the nutrients sufficiently. Also, in recirculating systems, when using unbuffered expanded clay, there are fluctuations in the nutrient tank, which can also lead to over- or under-fertilisation.

In recirculating systems in which the nutrient solution keeps leaving the tank and running back, the pH and EC value can be easily changed by an unbuffered or contaminated substrate. These factors also play a role in waste-to-drain systems, albeit a smaller one.

It is essential to point out that in these systems, the roots are exposed to the air, and constant irrigation is necessary so that the plants can develop without problems and do not dry out. As soon as a lack of moisture stresses the roots, they are severely damaged because they have no protection as in Coco substrate, in which the root ball is less exposed to the air and therefore dries out much more slowly than with expanded clay. On the other hand, if these factors are under control and no mistakes are made, the growth really explodes in such a hydroponic system.

The irrigation methods of the hydroponic systems sometimes differ enormously. There are systems like the Dutch Pot which have permanent 24-hour watering. Some growers water their plants every 15 minutes; others prefer watering them for 15 minutes every hour. Depending on the selected system, an optimal irrigation program must be set, just like when growing in rockwool.

Every grower has to find the ideal watering time for the grow, as this depends on several factors: temperature, humidity and ventilation. If the substrate dries out quickly, more waterings must be carried out, each with the development phase and needs of the plants’ optimal EC value. In hydroponic systems with rockwool or expanded clay, the nutrient uptake of the cannabis plants is more effective than in Coco, which is why the EC value should be slightly lower. The plants must also be checked every day to find an optimal EC value for each strain.

Advantages of growing hydroponic weed

Growing weed in a hydroponic way offers some serious advantages. Let’s dig into that deeper!

1. Complete control of nutrients and pH value

Hydroponics allows you to control the nutrients your cannabis plants need completely. Dilute them with water and add them to the tank so there is zero waste, unlike adding nutrients to the soil which is comparatively ineffective as some of the nutrients always fail to make it to the roots. You can calculate accurate nutrient measurements to guarantee that your weed plants receive exactly the right amount each day. The risk of root burn from inadvertently giving too much fertiliser is eliminated. Many strains of cannabis plants require a correct pH value to grow properly, and again, hydroponics ensures that the guesswork is removed when it comes to testing the pH value.

2. Increased yields

The effective fertilisation leads to improved growth and better yields, the end goal of all weed cultivators. Your precious plants don’t have to waste energy trying to get nutrients from the soil. Hydroponics means that they are free to focus on putting their energy on developing strong stalks and lovely leaves and buds.

3. A better way of using space

A hydroponic setup uses less space as the soil needs a lot of space for the roots. You can group your plants more closely together, and more plants mean more weed, once the flowering season begins! It’s also less messy than a soil-based system, no need to spend ages sweeping spilt compost from floors.

4. The roots are visible so you can quickly diagnose problems

Observing the root system is an excellent way to spot signs of nutrient deficiency or stress as problems are usually revealed more rapidly than the parts above ground. If the roots are not white, you need to take action – brown or dark roots are only seen in unhealthy plants.

5. Speedy growth rates

Hydroponics provides direct access to the nutrients your cannabis needs, close monitoring of pH and constant oxygen supply. As long as you have adequate lighting and good temperature control, plants will grow faster than plants that grow in soil. They are supplied with everything they need so that practically no energy is wasted. Plants which grow healthy and vigorously are also more resistant to diseases.

6. No need to worry about pests and diseases

Many pests and diseases thrive in soil. A hydroponic system instantly offers the answer to all these risks.

Disadvantages of hydroponics

Besides the advantages of growing hydroponically you have to be aware of the disadvantages in order to decide if growing hydroponically is the best option for your culture. So what are the disadvantages?

1. Initial investment costs

The cost of the equipment is more expensive than a crop that uses soil. However, after several successful crops, you will almost certainly realise that the investment is worth it.

2. Learning curve

Although hydroponic cultivation is not difficult, it requires a solid plan of action. You learn it by doing it so take your time and enjoy the learning process

Best hydroponic medium to grow weed with

One of the first things you need to do is choosing a growing medium — this is a substance that supports the axis between the stem and roots. The growing medium allows the roots to descend into the water to access nutrients. There are many types of medium, each with its own set of advantages and disadvantages. It’a matter of experience to see which is best for you.

1. Clay Pebbles

Clay pebbles are highly popular as they are inexpensive and easy to use; just watch the pH levels as they may need to be altered because of the clay. Place in a basket with gaps for the roots to penetrate into the water.

2. Rockwool or mineral wool

Rockwool is also a common choice and is a substance made from spinning fibres from basaltic rocks into a wool texture. Rockwool is really good at retaining water, which enables proper hydration of the top root system. However, it is not very environmentally friendly and is also potentially harmful to your health.

3. Perlite

Perlite is an amorphous volcanic glass that swells when it is exposed to high temperatures. You may have come across it in compost to prevent compaction and to provide aeration, and it serves the same purpose when used in hydroponics.

4. Coco Coir

Coco coir is the hairy fibre from coconuts and enables proper aeration and moisture retention. Coconut fibres also help protect roots from being affected by plant-stimulating hormones.

Best hydroponic system for weed

All systems use a water solution enriched with nutrients. However, some installations vary according to various factors such as circulation and water exposure. You can buy hydroponics setups online, or you can save money and build one yourself if you have DIY expertise.

1. Deep water culture

Deep water culture is an excellent place to start for beginners and is probably the least expensive option. Cannabis plants are placed in buckets filled with a nutrient solution, and an air pump provides a constant supply of oxygen.

2. Flood and drain system

This type of system consists of several buckets hung over a growing tray which has two waterways; an inlet and outlet, both of which are connected to an external tank that contains nutrients. A flood and drain system is a very stable method of cultivation and is highly recommended for novice growers who need a secure hydro system that will still provide great results.

3. Drip system

A drip system is an active hydroponic system, which means that it utilises a pump to supply your plants with regular nutrients and water. It is also known as a micro-irrigation system. The system features small emitters to drip the nutrients directly onto your cannabis plants.

4. Nutrient film technique

If deep water culture is similar to growing cannabis plants in a pond, then the nutrient film technique equates to growing weed over a river. This system involves placing weed plants into an angled tube so that water can flow in one side and leave the other via gravity. The roots descend into the tube, where they are exposed to the flowing water. The water enters from a tank with a pump and airstone and returns once the cycle is complete.

5. Wick system

A wick system is a simple hydroponic setup that features a growing tray. A tank of water is placed underneath from which several wicks exit and enter the growing medium. Water flows up the wicks and hydrates the medium without a pump being required.

Best nutrients for hydroponics

In hydroponics, the nutrients the plants need are mixed with the water the plants receive. Here you have two options:

1. Liquid food

Liquid food needs to be mixed with a certain amount of water. If the plant then absorbs water, it also absorbs nutrients, allowing it to grow.

2. Capsules

The capsules are slightly different. These have to be mixed with water, but they will sink to the bottom anyway, no matter how much you mix. When the plant is hungry, it secretes a specific acid that ends up in the water and causes the capsules to disintegrate. The nutrients in the capsules are thus released and mix with the water. The nutrients are then absorbed in the same way as with liquid food. If the plant absorbs some of the water, it automatically absorbs the nutrients in the water. The handy thing about this system is that you can easily give the plant a lot of nutrients, without running the risk that the weed will immediately consume everything.

Hydroponics can seem daunting but the effort is worthwhile

Hydroponics can seem off-puttingly complex to a novice grower. All the various components and methods are a lot to take in. Our advice is to start small, select a reliable hydro weed strain, and regularly tend to the needs of your plants. Using a hydroponic system is very rewarding, and your hard work will pay off with quick harvest time and generous yields.

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.

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.

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.
