Abstract

Examples may include a method of cultivating cannabis plants. The method may include placing a first cannabis plant of a plurality of cannabis plants in a first tray of a plurality of trays. The method may also include placing a second cannabis plant of the plurality of cannabis plants in a second tray of the plurality of trays. The first tray may be at a first height. The second tray may be at a second height, and the first height may be different the second height. Furthermore, the method may include flowing a nutrient mixture from a reservoir to the plurality of cannabis plants. In addition, the method may include returning a portion of the nutrient mixture to the reservoir after flowing the nutrient mixture from the reservoir to the plurality of cannabis plants.

Claim(s)

1. A method of cultivating cannabis hydroponically, the method comprising: placing a first cannabis plant of a plurality of cannabis plants in a first tray of a plurality of trays; placing a second cannabis plant of the plurality of cannabis plants in a second tray of the plurality of trays, wherein: the first tray is disposed on a first shelf of a first rack system, the second tray is disposed on a second shelf of the first rack system, the first shelf is at a first height, the second shelf is at a second height, and the first height is different from the second height; flowing a first nutrient mixture from a first nutrient reservoir to the plurality of cannabis plants; returning a portion of the first nutrient mixture to the first nutrient reservoir after flowing the first nutrient mixture to the plurality of cannabis plants; exposing the plurality of cannabis plants to a first artificial light source having a first limited spectrum; growing on the first rack system each cannabis plant of the plurality of cannabis plants without producing flowers; transporting the plurality of trays from the first rack system to a second rack system; flowing a second nutrient mixture from a second nutrient reservoir to the plurality of cannabis plants; exposing the plurality of cannabis plants to a second artificial light source having a second limited spectrum, wherein the first limited spectrum comprises a different wavelength range than the second limited spectrum; and growing flowers on each cannabis plant of the plurality of cannabis plants on the second rack system.
