Foliar Symptomology, Nutrient Content, Yield, and Secondary Metabolite Variability of Cannabis Grown Hydroponically with Different Single-Element Nutrient Deficiencies --

"The onset of individual deficiency symptoms did not always correspond with elemental analysis of foliar tissues. Cultivators should take an integrated approach in diagnosing nutrient deficiencies and take timely corrective actions to optimize productivity and minimize losses to yield and quality."

Terroir (/tɛˈrwɑːr/, French: [tɛʁwaʁ]; from terre, "land") is a French term used to describe the environmental factors that affect a crop's phenotype, including unique environment contexts, farming practices and a crop's specific growth habitat. Collectively, these contextual characteristics are said to have a character; terroir also refers to this character.

Some artisanal crops for which terroir is studied include wine, cider, coffee, tobacco, olive oil, chocolate, chili peppers, hops, agave (for making tequila and mezcal), tomatoes, heritage wheat, maple syrup, tea, and cannabis.

-->Powdery Mildew Risk Assessment Index (RAI)
Grape powdery mildew risk assessment index (RAI) is useful for determining disease pressure and how often you need to spray to protect the crops
INSECTS:

Sciaridae are a family of flies commonly known as dark-winged Fungus Gnats that infest soil, potting mix, other container media, and other sources of organic decomposition. Larva will be found inside the plant tissues near the soil. 

-- Spider mites are members of the Tetranychidae family, which includes about 1,200 species.

--- Broad mite (Polyphagotarsonemus latus, Family: Tarsonemidae), is a microscopic species of mite found on many species of plants

---- Hemp russet mite (Aculops cannabicola, Family: Eriophyidae ) are smaller than conventional spider mites but larger than the broad mite, and exists only on Cannabis plants

Closed Loop No Till Harvest - Green Life Productions - Nevada
Steve and GLP have perfected a no-till living organic soil system indoors while still meeting Nevada’s stringent safety regulations. 

No synthetic fertilizers, fungicides, or pesticides — just compost tea and the occasional fish emulsion or liquid kelp. The soil is rarely disturbed. 




- GLP uses 60-70% reclaimed water with a catchment that treats water with filtration and UV sterilization before being recirculated.

- Installed Fohse A3is (https://www.fohse.com/pages/a3i) in every room right down to veg.
