Growing Weed in Water Using Hydroponics

Last Updated: December 14, 2021By Joshua Mezher

Growing cannabis

Cannabis, or weed, has the ability to grow almost anywhere, be it under different climates or varying conditions. In fact, growing weed at home has a lot of pretty straightforward approaches, and one of the ways to do it is by using hydroponics. 

The word “hydroponics” is derived from Latin that literally translates to “water working”. 

Hydroponic weed is the method of growing weed such that each plant grows in a flow or bath of water that is heavily oxygenated and highly enriched with beneficial nutrients. No soil is used in this process, and instead, the plant grows in a sterile, inert growing medium.

All of the nutrients required for the weed to grow are mixed in a solution in the water in which the growth process takes place.  This unique method of growing plants took birth over a century ago when it was created by William Frederick Gericke.

Although initially it was meant for just vegetables and garden plants, it was soon realized that this is a smart method of growing weed / marijuana.

In a hydroponic system, the plants don’t need to expend energy growing big root webs to absorb the nutrients. This is because they are set up so that they are able to consume all the nutrients directly. 

The plants take in their required nutrition both from the water and the air, therefore, it’s necessary to maintain a perfect atmosphere in your hydroponic system.

As you can tell, growing hydroponically can get complicated and expensive.  That’s why we recommend growing with natural soil, especially for beginners.

How to Set Up a Hydroponic System to Grow Weed

There are several ways of growing weed hydroponically. Of those methods, one of the most popular ones is the deep water culture method. It’s a simple indoor method that requires the least amount of materials and works well for beginners who are trying this for the very first time.

The steps are as follows:

  1. Fill the reservoir with the necessary amount of nutrient solution.
  2. Suspend the root of the weed plant in the solution. This allows the roots to take in all the nutrients constantly and steadily. It also provides a continuous supply of water, nutrients, and oxygen.
  3. Keep adding oxygen to the water.
  4. Use an air pump to add the oxygen. An air stone pump can also be used to create bubbles. This is a good way to keep your weed from drowning.

Benefits of Growing Weed Hydroponically

There is one reason in particular why some consider growing weed hydroponically better than soil-grown weed. That reason is yield.  Hydroponics, when done correctly, can yield about 20% more than soil grown weed. That’s why it’s the preferred option for commercially grown medical marijuana.  Here are the several benefits of growing weed hydroponically:

High quality weed that’s efficient 

Of the reasons why hydroponic weed is sometimes preferred, one of the top-most is that it allows you to have weed of the highest quality, without having to wait for the most ideal environmental conditions for growing it outdoors. 

This high quality is achieved because the hydroponic system makes complete use of water, nutrients, and the growing space efficiently.

Produce more weed than normal

The hydroponic method allows you to produce higher yields of weed from a particular plot size, which is a huge advantage when compared to soil-based cultivation when growing commercially.  However, this yield increase is negligible when growing smaller, personal amounts of cannabis.

It’s only the availability of light that limits the plant’s density in a hydroponic growth room. Quicker maturity also leads to an overall higher yield. If ideal conditions are maintained, growers can even choose to harvest about four to five times a year. 

Hydroponics reduces the risk of diseases 

Hydroponics reduces the risk of plant disease and pest infestations, as a result of which you don’t need to use a lot of pesticides. This leads to the creation of a product that is much safer for medical marijuana patients.

Because of this, hydroponic marijuana can benefit patients with cancer and AIDS because a regular intake of chemically contaminated marijuana can cause several unwanted side-effects.  Of course, you can also avoid harmful pesticides and other nasty stuff by growing weed at home, whether hydroponically or in soil.

More Control Outdoors

As hydroponics allows you to grow weed indoors, you can have much more control over the environment than you would have outdoors.

It lets you supervise the factors that affect the growth and quality of the plant along with its yield. This can lead to the production of higher quality weed than plants grown normally.  However, all that supervision and care creates more work and cost for the grower, and allows for more things to go wrong during the grow.

Grow in Small Spaces

If you have limited space, hydroponics can be a good option for you.  Since hydroponic weed can be grown in your bedroom or inside a closet, space is less of an issue.  Though with autoflowering cannabis and a quality soil grow kit, high quality weed can be grown naturally in very little space, and at less cost.

A hydroponic system serves great for those looking to maximize yield and have total control of their grow.  However, it can be complicated and costly for first time growers. Not only are there various options available, the process for setting up and monitoring a hydroponic growth system can be time consuming.

If you want to grow weed in a way that gives you control over the growing conditions and lets you do it within the space you have, hydroponic weed might be the choice for you. 

However, if you’re looking to save money and reduce risk, while still having a bountiful tasty harvest, stick with all natural soil grow methods, like a Pot for Pot’s Complete Grow Kits.
