This averts the chances of any leakage and keeps your growing area safe. This highly reliable hydroponic grow system is undoubtedly ideal for every gardening enthusiast.



To Consider while Choosing the Best Indoor Grow System

A few important things to consider before:

  • Types of Systems

You need to be sure of the type of system that you want to use for growing your weed.

There are 6 systems in total and all of them differ from each other in terms of use. Choose the one that you believe is the easiest for you.


  • Required Yield

Some systems accommodate a lesser quantity of plants while others do the opposite. Which one is best for you is totally dependent on your requirement.

If you want higher yields, go for a bigger system and if your need can be served with a few pots, go for a smaller system.


  • Cost

You would have understood by now that the cost of the kit has a lot to do with its features, number of components, and size. Therefore, you will find varying costs for these systems.

The best way is to fix a budget beforehand and then shortlisting the models as per the requirement. Even if your chosen grow system doesn’t include all the vital parts, you can always buy them separately.

However, I’d strongly suggest you keep your budget flexible enough to get a complete hydro system.  It is a very tiring experience to collect all the components individually.


  • Customer Service

Most of these indoor grow systems come with instruction manuals to help you out. But for additional help, the customer service is still highly important, especially if you are a newbie. Make sure the customer support is good and easily accessible.

This makes it easier for you to reach them immediately in case you get stuck somewhere.

Different Types of Indoor Hydroponic Grow System.

You cannot find the best hydroponics system for cannabis if you can’t differentiate between the various kinds of these kits.

First of all, you ought to know what hydroponics means and how does it work, as it will let you have a better understanding of the subject matter.

Hydroponics simply refers to an unconventional way of the plantation, which doesn’t generally require soil. These systems use still growing mediums for the development of your plants.

The system provides a completely regulated and controlled atmosphere to the plant with a liquid nutrient feed that has a stable pH. This helps the plant to thrive and nurture at a faster pace.

The plant keeps dangling right on top of the water, due to which the liquid nutrient is sent straight to the roots. This allows the plant to receive all the vital nutrition without putting in too much struggle in comparison to soil growth where roots have to do all the groundwork of locating and extracting the nutrients for both survival and growth.

You might be thinking it is something new, but it isn’t. History shows a number of earlier cultures who made use of this system for the same purpose. And now, it has become so popular that a huge number of gardeners are switching to this option for pleasing their gardening interests.

These systems are specially used for planting cannabis or marijuana these days by a lot of people. And well, that’s the exact reason why you are here too, isn’t it?


Here are the 6 Major Types of Hydroponic Systems.


1. DWC System ( Deep Water System )

This is one of the most prevalent systems because it is highly effective when it comes to planting cannabis.

This hydroponic system keeps the roots dangling above the nutrient liquid all through their development period. The roots are hanged in a container having a nutrient solution while the unit hangs from the middle of the cap.

The grow system also uses an air pump for delivering air to the plants for better growth.


2. Aeroponic System

In the aeroponic system, the quantity of water used for the growth of the plants is very less and it doesn’t use soil at all.

This might sound like a very absurd thing to you or you might be thinking how come a small quantity of water, that too without soil, can aid you in the plantation. But, trust me, this method is highly operational and delivers exceptional results.

Another benefit of this system is that it lets you save up a lot of room by allowing you to plant your cannabis in both upright and parallel positions.

The aeroponic system doesn’t just make planting easier, it also delivers high production.


3. Drip Hydroponic System

This system directly dispenses the water to the roots of your weed while dribbling to the soil drop by drop, just like a drip.

Due to this gradual release of water, there are very thin chances of soil preserving the water for your cannabis because almost all of the water gets consumed and none is left behind.

So, this method makes sure that all the nutritive elements efficiently reach the roots of the plants.


4. EBB and Flow System

This grow system first submerges the whole place where harvesting has taken place and then allows that liquid to get drained.

Also uses an underwater pump for sinking the growing area. This structure can be used with numerous growing mediums. There are many things that could be used for filling up the growing place like gravel and grow stones.

Their presence aid in efficiently draining the water away. And the usage of growing medium in separate units also gives you the liberty of moving around your plants with ease.


5. Nutrient Film Technique (NFT)

This structure also keeps the plants dangled over a container while constantly delivering them the nutrient liquid for expediting their growth.

The container is used for grasping all the additional water. The same liquid keeps getting sprayed back on the weed through a pump.

This method needs to keep the crops in a vertical position and it doesn’t really use a developing medium, as the weed is kept in a net pot.


6. The Wick System

A wick system doesn’t use any moving components and it uses a very simple method for plantation. What happens is that a wick absorbs the nutritive liquid from the tank and sends it to the weed using the growth medium.

You can use multiple growing mediums with this method like coconut fibre, perlite, and more. This method is not very effective when it comes to planting cannabis because it supplies lesser water than cannabis require.

Tips for Obtaining a Healthy Yield

The following tips will help you achieve a healthy production.

  • Regularly water your plants.
  • Keep monitoring the moisture levels through a hygrometer.
  • When leaves start turning yellow and falling off, cease the nutrient supply and only continue with the water.
  • When around 3/4th of the white hairs get a yellowish hint, that’s the time to begin harvesting.
  • If the sprouts easily come off instead of winding, your plant needs more water.
