Nitrogen deficiency. Nitrogen deficiency is a deficiency of nitrogen in plants. This can occur when organic matter with high carbon content, such as sawdust, is added to soil. [1] Soil organisms use any nitrogen available to break down carbon sources, making nitrogen unavailable to plants. [1] This is known as "robbing" the soil of nitrogen.
e. Cultivation of cannabis is the production of cannabis infructescences ("buds" or "leaves"). Cultivation techniques for other purposes (such as hemp production) differ. In the United States, all cannabis products in a regulated market must be grown in the state where they are sold because federal law continues to ban interstate cannabis sales.

It was formerly classified as a pathovar of Pseudomonas syringae, but following ribotypical analysis, it was reinstated as a ...
These indoor environmental controls prevent crop loss and optimize yield, but often demand large amounts of electricity. Cannabis cultivation consumed approximately 0.11 percent of all electricity used in the US in 2017, while regulated cultivators used 0.03 percent. However, actual electricity consumption by cannabis cultivators may be much ...

In contrast to cannabis for medical use, varieties grown for fiber and seed have less than 0.3% THC and are unsuitable for producing hashish and marijuana. [93] Present in industrial hemp, cannabidiol is a major constituent among some 560 compounds found in hemp.
Cannabinoid hyperemesis syndrome. Cannabinoid hyperemesis syndrome (CHS) is recurrent nausea, vomiting, and cramping abdominal pain that can occur due to prolonged, high-dose cannabis use. [4][5] Complications are related to persistent vomiting and dehydration which may lead to kidney failure and electrolyte problems. [2]
Top-fed deep water culture is a technique involving delivering highly oxygenated nutrient solution direct to the root zone of plants. While deep water culture involves the plant roots hanging down into a reservoir of nutrient solution, in top-fed deep water culture the solution is pumped from the reservoir up to the roots (top feeding).
