hahahahahahahahahahahahahahahahaha. i use c02 all the time to control bugs, even when i can't see signs of an infestation. it works well. as for the grape juice, i give that about a 0% chance of working on the bugs (especially cuz they'll migrate while the plant's drying anyways), and about a 75% chance of moldy buds. maybe if i ended up with some dirt weed i could use that to spice up the flavor lol. Mite-Rid spray works but it runs around $30 for a small bottle. it won't eliminate the problem, but it's all organic and it'll control them for about a week per application. you can use this twice per crop, which would almost finish your grow. i would use this and also gently wipe the leaves down every day to prevent new webbing. you can check out my old threadyea Max just tell the guy it sucks, that works even better... LOL.
Let me elaborate : when they are ready for harvest, trim all branches dip in grape juice, (to make sure any residue will be removed) and i hang upside down, the grape juice is acidic and a fan will remove grape juice in 15 min of hanging upside down, the resin will dry as usual. or you can try max way.... Oh wait, he just said it sucks... and raise your co2 LOL LOL LOL ha ha ha Please try his way first, tell me how that works out for ya.... LOL LOL
