I want to take preventative measures to ensure my grow stay pest free!! I’ve looked at pure crop 1 and there’s a spray that buildasoil.com offers as well. I’ve noticed a gnat or two in my garden. Picking up some yellow sticky traps this weekend and looking to get some type of spray to help prevent pests and also mold. Nematodes for an infestation or should I use some before I notice an infestation? I am growing all organic and want to use an organic product that’s not harmful to my plants and only use something stronger if I have a bad infestation... thanx for any input farmer fam!
