How to Grow Marijuana with Hydroponics?
To grow marijuana with hydroponics or hydroponically in simple terms means that the
plants are grown in an inert and sterile growing medium rather than growing in soil. The
nutrient requirements for all the plants are supplied as water is mixed to the nutrient
solution. Looking into the fact, all plants are 85-95% water with the remaining parts being
carbon, hydrogen, and oxygen.
These elements can be extracted from water and air. Hence, the nutrients comprise of a
very small proportion of the whole weight of the plant. So, we need to control the entire
atmosphere of the plants to produce the perfect crops within hydroponic environment.
Plants don’t need to be in living soil and that is the case for marijuana plants too. They need
phosphorus (P), nitrogen (N), calcium (Ca), potassium (K), sulphur (S), and magnesium (Mg).
These are the major elements and the small ones known as micro-elements are chlorine
(Cl), iron (Fe), boron (B), Manganese (Mn), Copper (Cu), Zinc (Zn), and Molybdenum (Mo).
Nutrients, water, and air are introduced to the roots of the plant hydroponically through the
growing mediums. Hydroponics bypasses the energy needed for plants to acquire those
nutrients; this will lead to effectively growing plants that take less time to grow.
Set-Ups for Hydroponic Marijuana:
The process of growing is done using Flow and Ebb systems, which are very advanced (if not
the most advanced ones) systems for growing weed. These systems are easy to use. The
working is described as follows: One container, which contains the nutrient solution, is
located below a tray. The plants are contained in the tray, which also contains a growing
medium like Rockwool. Nutrient solution is filled in the growing bed by a small pump to feed
and water the plants.
The timer later shuts the pump off and the nutrients contained simply drains freely into the
reservoir. The Ebb and Flow system is preferred because of the maintenance cost, which is
on the lower side. The productivity is high and usage is easy. The system is ideal not only for
beginners, but also for senior and experienced gardeners.
There are other systems – Sea of Green (SOG) and Screen of Green (SCOG), which are used
primarily in commercial operations where there is a lot of emphasis on speed and yield is of
utmost importance. The cannabis strains that work well with the equipment need to be
capable of flowering even after a short vegetation period.
The other option is to buy all the gears from the nearest hardware stores and also buy a
ready already built room to grow. This will be a costly affair, but all the parts will be included
and the user can save time and energy. An 8 plant unit will cost around $300. EBay.com, on
the other hand, has a lot of gears, which are light on your pockets too.
