Learn about indoor Hydroponic grow systems

When looking for hydroponic systems, you will find that there are plenty of options to choose from. However, it all boils down to personal preference and requirements. Each of those hydroponic systems for grow systems carries its pros and cons. Most shops provide complete kits with an excellent manual, and those are ideal if you can afford them. However, one should always get the hydroponic for the indoor grow systems that they need. One can even design their own system based on certain principles.

Aeroponics –
The art of growing medicinal marijuana with the roots that hang inside a light and water tight box, with fine mist created by small emitters. The plants enjoy an aerated environment with nutrients on a regular basis because of the mist.


Continuous Flow and Top Feed System –This is another good system that helps to create a nonstop supply of nutrients into the top of indoor grow systems and is very much like the NFT system or the Ebb and Flow system.

Deep water Culture (DWC) / Recirculating Direct Water Culture (RDWC) / Bubbleponics hydroponic system – The concept behind the hydroponic used in grow systems is different as the roots swim in the solution of nutrients. The system is very similar to the one used use in aquariums and offers sufficient oxygen and aeration. One can set up the system over a plastic watertight drum.

Drip irrigation hydroponics – This is a very different hydroponic system that is used for growing marijuana outdoors. The marijuana plants get fed from the top with the help of the small emitters. The nutrient solution gradually drips down and feeds the plants. This is considered to be an efficient system with no issues of evaporation for the marijuana.

Ebb and Flow hydroponics – There is a tray placed above the reservoir that carries the pots. The nutrient solution is pumped up by the reservoir into the pan that flows past the pots and keeps them fed. The remaining nutrient solution goes back into the reservoir grow systems.

Nutrient Film Technique (NFT) – Under this system, the plants are held together over a slightly slanted tray, and this keeps the aeration of the plants roots in good order. This is a very efficient system as the thin film of nutrients that flows from top to bottom and run past the marijuana roots.

Wick System – The basic system connects the pots with a dense ‘wick’ dipped into the reservoir, and the capillary action takes care of the rest. Thus, this is a very basic system that works best for a couple of plants. Moreover, there is no need to buy any pumps, timers or aeration systems for the indoor grow systems.

Sea of Green – This is a Dutch method that creates a Sea of Green heads (kolas).

Screen of Green – This is another Dutch growing practice that is very much like the Sea of Green. You get to learn several exciting things for your grow systems.

Continuous Flow / Top Feed Grow Systems

Top feed systems make use of an emitter that feeds the individual plant at its base. The emitters are fixed to a multi-valve unit pump-fed from the reservoir. A drainage hole takes care of any run-off from the plants. However, you will need to make some adjustment to the Top feed systems in order to get right quantities. A good starting point with the above system would be 15 minutes feed 3 to 4 times a day.


Ebb and Flow Grow Systems

These systems are perfect for growing in Rockwool. The low maintenance systems is preffered by most amateur growers where the plants are placed in their pots that are lined in a tray carrying around 6” of nutrient solution. The base of the tray is flooded periodically from a reservoir with the help of a timed pump. One can start with four times per day so as to offer enough solution to the base of the plant. The solution flows back to the same tube when the pump is switched off. An overflow pipe is fitted to take care of flooding and get the required level for the solution. Just keep in mind that the reservoir should be at a lower level than the growing area, so that any solution will drain back even if it is left in the growing tray accidentally, thus removing any chance of flooding in the indoor grow systems. A good starting point for watering would be to flood the tray 3 to 4 times during daylight for 15 minutes. However, the watering timings can vary according to the size and strain of your plants.

Wick Grow Systems

A wick system runs in a passive way as there is no need of any pumps here. The nutrient solution is well aerated and pulled up to the plant with the help of a wick. Make use of a thick and dense acrylic cord to apply the force of capillary action. The system allows the plants to absorb only the right amount of liquid it requires. Place the upper end of the wick in the growing medium for the plant and the lower end hanging in a reservoir that carries the nutrient solution. This is the right system for the beginners as there is no risk of any leaks or floods or overwatering the plants.

The Reservoir

When using the nutrient solution reservoirs, get them as large as possible as those reservoirs should supply at least two weeks of nutrients. Those huge vessels carry the water and nutrients required by the plants and are pumped through. A lid or covering for the reservoirs is essential to prevent any evaporation. Place the reservoir close to a water source such as the garden hose or something as readily available like that. A clean plastic container with a lid can work as a reservoir. It should be cleaned once a week and one should top up with fresh water when essential or even change the solution completely.
