i sprayed 2-3 times a week in flower, but i had pm real bad i was dealing with c99, she gets it real easy then it builds and can infect your other plants real fast. i only eneded up keeping my fruit punch pheno got rid of the other 2 i would spray them and next day it was there again.
started to see the new growth doesn't really get PM so that's when i got the idea to take cuts and trash them moms eventually i beat it. good idea is also when ur buds are just forming to spray them real good that way when they grow around the area u sprayed no pm will be inside the bud. tha parts i sprayed seemed to be ok for about 10-14 days. if u make to strong a does u will notice your pistils turning brown early, it didnt affect my plants it seems. when i chopped i also made 2 trays with water in them one had greencure in it one was just water. i would submerge my buds into the greencure mix then rinse them off with the water mix before i hung them. i made sure to put a fan blowing on them the 1st night to dry the water off. final product had no complaints and i didnt see any PM on the dried buds
