Started silica 2 weeks ago... doing a foliar every 7 days with it... definitely makred improvement in plant health, but hard to distinguish speifically from all the other amendments. good tip though and silica is VERY powerful! cheers!
I would agree very overpriced.. but I AM glad to hear your positive results feedback!
Notice that and the "PureCrop" are oil based with some ctric acid... oils and fats are the basis for plant health... go back and looka t the plant health pyramid again.. notice level 4 is producing complete proteins and sythesizing plant pjhenolic compounds at top level! (Same thing we want in growing Cannabis by the way)
So my approach is to get the plants' health up to that level on it's own.. through correctly balanced mineral nutritiona nd biology. It's tricky without tools like plant sap testing.... but I KNOW it can be done.
