How to Grow Hydroponic Cannabis?

Hydroponic cannabis is simply cannabis grown in water that’s rich with the nutrients needed by the plants, and in an inert medium rather than traditional soil. This approach does provide some advantages to growers, which is why you might want to consider it yourself. First of all, you may not have soil available for indoor growing, and that could be costly to bring in artificially. There are also far fewer pest problems to worry about, since most of those are associated with the soil itself.

How to Grow Hydroponic Cannabis?

It’s much easier to exert a controlling influence on the quality of your cannabis when you grow it in water, because you can manage the levels of nutrients going into your inert medium, and you can carefully balance pH of the soil. Many growers find that their hydroponic plants are bigger, healthier, and even have higher potency. On top of all this, your crop will grow faster and in virtually all cases, produce a greater yield.

Step 1 – Get Your Hydroponic System Setup

There are two approaches to setup. You can either buy a complete startup kit that gets you ready for growing immediately and lets you learn the ropes at a slower pace, or you can do it all yourself from the ground up. If you’re doing it yourself, you’ll need a 3-gallon bucket for each plant, enough clay pellets to fill each bucket, one 1.5 Rockwell cube for each bucket, a growing table, a reservoir tank, a large water pump, plastic tubing, an air pump, air stone, drip line, and two drip line emitters per plant.

Next, you need to setup your reservoir with the water pump, air pump, and air stone, at a level below the grow table, so excess water can drain into it, and so water can be pumped to the buckets. The grow table should drain toward the middle, where tubing will conduct water back to the reservoir. The buckets can be filled with clay pellets, and they need to have holes drilled in the bottom which are smaller than the pellets. The tubing will be used to conduct fresh water and nutrients to the plants, and return used water to the reservoir.

Step 2 – Get the Necessary Nutrients

The three main nutrients needed for cannabis growing are nitrogen, phosphorous, and potassium, but to ensure a good crop, you’ll also want to purchase smaller amounts of magnesium, sulfur, zinc, boron, copper, calcium, and iron. During the vegetative phase, you must provide a solution rich in nitrogen, and during the flowering phase, it should be a phosphorous-rich solution. It’s better to buy the pre-mixed versions of these nutrients, so that you don’t have to guess about content level.

Step 3 – Growing and Tending

The most important thing to remember about tending is that it will be necessary to prune bottom foliage frequently because of the rapid growth enjoyed by hydroponic cannabis. This allows the all-important top buds to receive more nutrients and gain potency. You’ll also have to be on the lookout for tall-growing plants to break or tip over – trellising can solve this problem nicely, since it provides needed support and trains the growth direction.

Once you get the hang of hydroponic growing, you’ll probably be so pleased with the results, that you’ll never want to try it any other way.
