Hydroponic Setup

Some of the methods used to grow cannabis plants.

Deciding which hydroponic setup you would like to use is one of the biggest decisions you will have to make when building a grow room building a grow room. There are so many systems available on the market that it can be hard to choose which one you would like to use. Below i have listed some of the most commonly used hydroponic setups with a diagram and discription. Hopefully you can use them to help you decide which system is best for you. Each system requires different amounts of care and attention so take into account how often you can visit the garden and how much time you would like to put into it before you set up a grow room. Every hydroponic setup for weed require you to monitor the PH and PPM/EC values of the nutrient mix to keep things running smoothly, for more on this click here.

What hydroponic setup suites you best…

Pots & Coco or Soil…

The simplest method of growing weed indoors is by using plant pots filled with Soil or Coco Coir as these mediums are very forgiving when it comes to over and under feeding, its also not quite as important to adjust the PH and EC of your nutrient solituion as the soil/coco do a pretty good job of this automatically. Growing cannabis in this way is pretty straight forward due to the fact that you just feed the plant when the medium is dry and the pot feels lightweight. If the medium is wet and the pot is heavy, then the plant can be left alone until it begins to dry out. Although this method of growing is so simple and successful it will not typically produce results as good a more advanced hydroponic setup

 

Aeroponic Grow System…

Aeroponics is a method of growing where the roots of the plant are anchored in a net pot with clay pebbles, the net pot is then suspended in a chamber, constantly sprayed with nutrient solution from the tank underneath. This kind of hydroponic setup gives the roots instant access to oxygen, nutrient solution and lots of room for 24 hours a day. The nutrient solution in an aeroponic grow system will need to be topped up every 2 or 3 days and completely emptied and refilled at the end of every week. If used correctly, these systems are capable of producing outstanding yields.

Autopot System…

Autopot systems require no electrical air or water pumps as the plants are bottom fed using gravity and an aquavalve. The plant pot sits in a tray that gets flooded with nutrient solultion, as soon as the tray is empty of water more will be released in. The aquavalve controls the amount of nutrient solution that is released into the tray, this is similar to the way toilets work when flushed. Growing with autopots allows a grower to leave the garden unattended for a long time. It is likely that the yield will be low using this hydroponic setup.

Bubbler Pot System…

Deep Water Culture systems, also known as Bubbler Pot systems operate in a way where the plants roots are in a clay pebble net pot that sits above a container full of nutrient solution. The water is oxygenated by an air pump and an air stone that is submerged in the water. The roots of the plant are left to dangle openly where they can access a constant supply of oxygen and nutrient solution. It is possible to buy ready made systems that will automatically top themselves up with nutrient solution when necessary. If a massive yield is you what you are looking for then this is the grow room setup that i advise you to use. In my opinion most effective and easiest to use hydroponic system for weed on the market. Bubbler pots are available in different sizes just like normal plant pots, they usually range from around 20 litres to 80 liters so the roots always have lots of room to grow. Click Here or on the images above to see a bubbler pot kit.

Dripper System…

In every professional hydroponic set up there will be a high quality dripper system. Dripper systems consist of a reservoir, a drainage tray, plant pots and a water pump. The plant pots sit on the drainage tray above the reservoir so that water can be pumped up into the pots through thin tubes then the excess water drains back down into the reservoir. This is good because the plant’s roots are never sitting in a puddle of nutrient solution and no nutrient solution i ever wasted. The water pump should be on a timer to schedule feeding so that the roots of the plant can dry out slightly and the plant can gain access to oxygen. Dripper systems are good for growers who wish to grow with the simplicity of pots along with gaining the advantages of timed automatic feeding. A good quality hydroponic set up will ensure ensure great results with a small amount of maintenance.

Flood & Drain System…

Flood & Drain or sometimes known as Ebb & Flow is a hydroponic growing system where the plants are in pots filled with a very airy medium such as clay pebbles, the pot are then put into a tray that is usually on a table above a reservoir. A water pump controlled by a timer floods the tray with nutrient nutrient solution, when the pump turns off the water drains back down the pump and into the reservoir, this allows time for the the plants to drink an then time to access lots of oxygen once the solution has drained away. An overflow is fitted to the tray to send any excess water back into the reservoir while the pump is still on. This type of system allows the grower to accurately keep on top of the PH and EC of the nutrient solution because as long as it is adjusted whilst its all stored in the reservoir there will be no inconsistencies.

NFT or Nutrient Film Technique is where the plants roots are dangling freely inside a water right gully that is sloped slightly, a water pump constantly recirculates a thin layer of nutrient solution over the roots. Because there is only a thin film of nutrient solution flowing over the roots, it leaves a lot of the root structure in open air to gain constant access to oxygen resulting in rapid growth. NFT systems work best for a grower who wants to use a lot of plants in a small space. Like most hydroponic growing systems, once up and running the NFT systems are relatively low maintenance.
