UC pot researchers working with ‘gray literature’
Here’s a weird fact: There is no industry standard for how much water a cannabis plant requires. Four gallons a day? Six? Growers are left to ask their friends, look at possibly-dicey web sites, and experiment for themselves. Growers of tomatoes or corn, meanwhile, can easily find such information by looking it up on the USDA’s web site, or asking their local extension representative.
