Devil's kiss

@Girl_Scout, Silica helps big time with powdery mildew. Also, when a pest "punches" into the leaf to drink, it chews on a mouth full of glass and moves on.      "as a rule of thumb silicon dioxide is glass so soluble silica goes into the plants and really strengthens cell walls we we know this from many      years of study one of the huge things it does is disease resistance you can almost eliminate powdery mildew with ample silica in the root      zone we've seen it multiple times growers had an outbreak of powdery mildew and you say what's going on well it turns out their silicon injector      broke and it stopped and the disease came back”            Bruce Bugbee: Indoor hemp production      youtu[dot]be/0I6awuKSp2c?t=2003       I am using the USU Crop Physiology Laboratory soilless media recipe this time around. It has calcium and silica (Wollastonite powder). I am also using potassium silicate in the feed. Potassium silicate also makes a very awesome emulsifier for neem oil spray. In the US, I get a pound of Agsil16H for 25 USD from Build A Soil:      buildasoil․com/products/agsil16h-potassium-silicate       I am not sure if silica would help with bud rot (Botrytis), but potassium silicate is still a cheap thing to add that is effective on several fronts.
