How to Grow Marijuana Hydroponically

by Jack Neander January 22, 2017

Growing weed in a hydroponic way is probably the most efficient way of cultivating marijuana. Weed is grown without a growing medium and the plant is fed directly through water dripping. Experienced farmers prefer this method because it has the potential of a much bigger yield, though it does require an initial investment. Since no growing medium is needed, the grower has everything under his control: he can feed the plant in terms of lighting and nutrients according to its biological needs and can create an optimum environment for maximum harvest. There is, however, the disadvantage which requires the cultivator to pay not only an initial investment, but also very close attention during the growing process.

Growing weed the hydroponic method means that the roots of the plant are not planted in soil; instead, they are in the open air, possibly in a growing medium such as clay pellets. This means that the soil is taken away and the plants’ roots are relatively exposed. The roots are fed by either a spraying or a dripping system, which means that water and nutrients are dripped or sprayed on the roots to avoid the roots from dehydrating and to ensure the plant receives all the chemicals it requires.

Traditionalists maintain that there is no better way to grow cannabis than to do it the traditional way, but proponents of growing weed-hydroponic way are adamant: the expected harvest is often 30% or more profitable. Hydroponic plants are in no way different than ordinary plants – it is only fed in a different way, and the feeding process is monitored more closely than with the time-honored means. Growers can control everything the plant needs, and scientists (believe it or not, NASA was among the first to go into growing hydroponically) have learned a lot. The method provides for a very scientific environment and a high return for investment.

Indeed, it does require quite a set-up. A small room must be dedicated to the project, complete with temperature control, timer switches to regulate the lights, the ventilation and just as importantly the dripping or spraying mechanism. Furthermore, there’s quite some engineering to do: since the plants are growing with nutrients driven by water only (hydro), there has to be an intricate system of plumbing to sustain the plant.

The basic system works as follows. The seedlings are placed in a growing medium – not to make sure the plant is anchored properly, but to make sure they are constantly being fed with the water solution. Some systems require the plants to be on some sort of floatation device, so that the plant drifts on the water solution with an ordinary aquarium air pump providing the roots with enough oxygen. Another way is to let the cannabis bush grow in pebble-like clay stones and have a spray or drip system provide the roots with nutrients solved in water on a very strictly-timed schedule. To have a medical analogy many of us can relate to: the plant has an IV hanging nearby – the food is fed directly to the veins and the required nutrients are both optimized and controlled, resulting in a higher harvest.

The advantages are simple: not only does the farmer expect a bigger fruit production, the grower also learns much more about the plant scientifically, because the growing weed hydroponic method demands the cultivator to act in an organized and methodical method traditional farmers need not do. Hence, the disadvantages: it does require constant time and attention. The grower needs to do plenty of research and has to be prepared to spend many hours (a day) and many months maintaining not only the growth of the plant but also the productivity of the equipment that is used.

Preparing for a project such as growing hydroponically is worth-while only when the grower is serious about the undertaking; the farmer needs to know that there is some money to be spent and the results are not necessary promising for a beginner. However, there is much information to be found all around us, and I truly believe that any enterprising man who is not afraid of home handy-work can pull it off. In fact, considering the potential yield, it would be silly no to try it. Here’s what’s more: as is the case with cloning, most growers attempt it sooner or later, because the promise is just too great.
