A lack of credible information about indoor cannabis cultivation led him to analyze, research, and author Indoor Marijuana Horticulture in 1983. The book became a best ...
Indoor cannabis plant during flowering. Indoor growing became increasingly common when equipment, seeds and instructions on how to cultivate became widely available. So-called grow-ops (growing operations, often located in grow houses) are seen by many marijuana enthusiasts as a much cheaper way to gain a steady, higher-quality supply of ...
For indoor gardening, one of the most important requirements is the amount of light energy striking the surface of the plant ("incident light"), which can be measured in lux (lux = lumens / area illuminated in square metres). For indoor use, higher lighting efficiency produces more lumens per unit of area with less power and less waste heat.
Cannabis plants produce a unique family of terpeno-phenolic compounds called cannabinoids, some of which produce the "high" which may be experienced from consuming marijuana. There are 483 identifiable chemical constituents known to exist in the cannabis plant, [53] and at least 85 different cannabinoids have been isolated from the plant. [54]
Cannabis plants vary widely, with different strains producing dynamic balances of cannabinoids (THC, CBD, etc.) and yielding markedly different effects. Popular strains are often hybrids of C. sativa and C. indica. The medicinal effects of cannabis are widely studied, and are active topics of research both at universities and private research ...
The flowers of Cannabis sativa plants are most often either male or female, but, only plants displaying female pistils can be or turn hermaphrodite. Males can never become hermaphrodites. [ 3 ] It is a short-day flowering plant, with staminate (male) plants usually taller and less robust than pistillate (female or male) plants.
Further crosses will stabilise this trait and give a plant which flowers automatically and can be fully mature in as little as 10 weeks. Plant growing indoor under LED lights. Cultivators also favor ruderalis plants due to their reduced production time, typically finishing in 3–4 months rather than 6–8 months [citation needed]. The auto ...
