Just my 2 cents... I grow outdoor in Virginia.. very high humidity and lots of bugs...
Pure crop 1 is the only thing I spray on my actual buds... All the way up to 7 days before chop.. I'm growing in the ground .. planted in the pen we used to hold our goats... I use it almost every day.. I put 2 tablespoons per quart in a sprayer. Works wonders.. has not harmed plants at all.. I also put 3 tablespoons per 6 gallons of water every time I water or feed. This stuff does work great. I have no affiliation with P. C. 1.Im just telling you what my experience with this product is. I also use
hydrogen peroxide as a folier spray. Yeah weed plants are pretty hardy.. especially if u get the soil and nutes right. Also the 2 plants I put in goat pen are the healthiest plants I've ever raised.. so there both naturally more bug and mold resistant that the 2 I got in 45 gallon bags.. I'm running
roots Organics as nutes.. if u really want the top quality , best of best,, you have to get all phases of the grow right.. which is really , really hard to do in an outdoor setting. It's taken me 4 years of trial and error,,, but when u hit that sweet spot , as a grower it's soooo! Satisfying. I use more than what the label recommends,, so you have to try for yourself and see what works best... Als some bugs I noticed were getting immune to it I think.... Main pests here are thrips, and beetles.
