Growing cannabis in the soil also involves watering plants at regular intervals and monitoring fungi & mildew spots as well as taking regular actions to implement a rigorous pest prevention and control.

When planting cannabis in the lowest section of the tower, expect a DWC (Deep Water Culture) situation. Roots will grow in the bottom reservoir and cannot be cut (like for the root management of other plants such as chard, cabbages etc.). Trimming the roots of your cannabis plants (in an effort to protect your pump) will kill them. Although your tower is not meant to be used as a DWC system, surprisingly enough, plants growing with their roots fully submerged in the diluted nutrient solution always gave equal results (crop yield and potency) as the plants growing on the upper section of the tower.

In comparison, growing marijuana in the towers is not only cheaper but also, much easier! Much less work is involved since a unique soluble nutrient solution does it all from seedling to harvest! The same nutrient mix which we use to grow tomatoes, cabbages or strawberries is used indifferently to grow cannabis: this is a miracle in itself! Not only do we use the same nutrient mix for all crops, but it is also the same mix of natural minerals which are being used when growing cannabis from start to finish!

Speaking about overall expenditure costs, when growing plants in the soil, aside from the ongoing unaccounted labor involved, we spent over €50 – €100 ($60 – $120) per plant in nutrients and planting soil.

Here’s a close up of some frosty flowers.

For our trial run with the Tower Garden we used a variety named Grasshopper. This strain typically yields around 14g per plant achieving lofty heights of 18 inches; sometimes much less, rarely a little more. Its small size makes for good stealthy plantings and working into crowded spaces. Life cycle completes in 60 days from seed to mature flowers. The flowers are frosty and have a minty earthy smell. Here are some pictures from the end of the trial.

These plants go much bigger than their soil counterparts! Some were well over 24 inches tall and yielded over an ounce. 20 plants could yield well over a pound! We fell a little short of that.

Here you can see the reservoir lid. Tower Tonic A and B were the only nutrients used. We can see a deficiency here at the end, but the plants stayed green until the last 10 days with no signs of problem and therefore no significant impact on yield.

Here you can see planting sites on the tower. The smaller plants were planted later as replacements for males that were pulled. Using feminized seed would have eliminated the wasted space.

Most varieties of Cannabis are photoperiod sensitive. It flowers according to the length of nighttime darkness it receives. Using these photoperiod varieties would be nearly impossible in the Tower Garden outside as they would get to unmanageable size very quickly. If you can control the light cycle, initiating a 12/12 light cycle from seed or cutting would work with C. indica and shorter hybrids. But for outdoor and greenhouse growing dwarf autoflowering strains are the perfect choice.

I would highly recommend this system for inexperienced users or those wishing to simplify their methods.
