Using a Hydroponic System for Cannabis Growing

Table of Contents

What is a hydroponic system?

Cannabis may be grown hydroponically, as the name suggests, using water as its principal media. A hydroponic system for cannabis is more useful for growing cannabis indoors. Plants in a hydroponic system are hung over a water reservoir and cultivated in buckets or baskets packed with inert growth media.

How does a hydroponic system for cannabis work?

Hydroponic grow systems for cannabis are viable for cultivating high-quality cannabis in a controlled environment. A hydroponic system for cannabis is a growth technique that you can utilize in a wide range of settings, and it can produce plants more rapidly than other ways. For one thing, hydroponics enables gardeners to manage the nutrients their plants are getting, which may lead to larger buds as a consequence.

The advantages of the cannabis hydroponic system

If you want to set up a hydroponic system, expect the following benefits:

Easier nutrient uptake

In a hydroponic system for cannabis, nutrients are considerably more easily accessible to plants since they dissolve in water. Because there is no soil to go through, the nutrients float in water and immediately reach the roots.

Faster growth

It takes hydroponic plants a lot less time to grow than those grown in the ground. Hydroponic cannabis often develops 30–50% quicker and frequently provides higher yields than soil-grown ones.

Bigger yields

Thanks to the faster growth, hydroponic cannabis produces significant yields.

Choosing a hydroponic grow medium

Once you’ve chosen a growth medium, you’ll need to secure the stem and roots together. The roots will descend into the water if you want to get nourishment. Roots may breathe thanks to the inert medium’s open structure freely. The following is a list of the most frequent media used by farmers. Each media has its own advantages, so does each hydroponics setup.

When you’re just getting started, it’s all about experimenting to determine what works best for you. Some of the options you should try to include clay pebbles, Rockwool, Perlite, and Coco Coir.

Passive hydroponics vs. Active hydroponics systems

There are two types of hydro set ups: active and passive. An active system uses electric pumps to transfer nutrients and air stones to oxygenate the water. You can use capillary action rather than an electric pump to distribute nutritional solutions in passive systems.

How to create the best environment for your hydro setup

To ensure your hydroponic cannabis health and productivity, you must follow several responsibilities and procedures. When learning how to set up hydroponics, here are a few things to keep in mind:

Managing temperature

Ideally, the water in your hydro set up should be at least 65 degrees Fahrenheit (18 degrees Celsius) so that the plants can absorb nutrients and algae do not develop. However, the air temperature may be higher. Your cannabis plants will be happy if you can keep the temperature in your grow room at 75 F (24 C). All hydroponic cannabis systems must have the appropriate temperature to produce bigger yields. Likewise, ensure your grow medium has the best humidity for growing cannabis.

Proper lighting

There are many grow lights on the market, and each has its supporters and detractors. Your area, the distance between your lights and your plants, and your budget all play a role in determining which grow lights are best for you. It is preferable to use high-intensity discharge lights (HID) in bigger grow rooms with enough ventilation. As a rule, CFLs are preferable for compact spaces. CFLs may be more cost-effective for larger grow areas, while LED lights are better for smaller ones. Whichever cannabis hydroponic systems are at your disposal, they must be able to generate enough light at wavelengths ranging from 400 to 700 nanometers.

Optimizing nutrients

Premixed or powdered nutrition solutions provide all of the essential macro and micronutrients. However, hydroponic cannabis plants may be effectively grown using premixed solutions. Clay pellets and the nutrition film technique (NFT), sometimes known as the film technique, deliver nutrients to plants.

Feeding hydro cannabis

A notion known as the nutrient film provides nutrients to the roots of plants via a stream of water. Oxygenation of the water improves nutrient absorption by the use of clay pellets. Using clay pellets and the nutrient film technique are excellent examples of the many ways you may enhance your cannabis hydroponic system. The right nutrient content is a vital part of any cannabis hydroponics system.

Optimizing pH

Your hydroponics cannabis kit water should be at a pH of 7. You can produce tepid water using a reverse osmosis (RO) system. Until you can purchase a RO system, you can utilize distilled water. All hydroponic cannabis growing systems must have the correct pH to ensure the plants remain healthy while being as productive as possible.

EC and TDS values

Your hydroponic cannabis setup water’s electrical conductivity (EC) measures the total dissolved solids (TDS). There are a variety of effective pH meters on the market and meters that can measure both pH and conductivity (pH and EC). The EC level may determine the number of nutrients in your circulating water. Depending on how much nutrition your plants receive, you may “burn” your plants if the EC is too high or too low. Different stages in the growing of hydroponic cannabis will affect the EC. Ensure you have the correct values for your hydroponic setup for cannabis.

Does cannabis grow faster in hydroponics?

Yes, hydroponic plants grow 30-50% faster and produce significant yields. Nutrients are readily available since they enter directly into the root system.

Does hydroponics increase the yields?

With faster growth, the yields from hydroponic plants are consequently higher. If you are growing for commercial purposes, you can rest assured you’ll make decent profits.

Why is hydroponics expensive?

It relies on the amount of money you’re prepared to spend on your hydroponics cannabis setup. They might be as basic as a plastic bucket or as complex as self-draining and flooding systems. The latter is significantly costly, but they aren’t the only options out there.

Why does hydroponics not use soil?

A cannabis hydroponic system is soilless to allow the plants’ nutrient uptake to be as efficient as possible. It results in more yields without having to use too many inputs.
