You should definatly do something about it before you start another grow in there or chances are that you'll end up with the same problem. Also, what about going over them lightly with a compressor/blow gun before ya harvest. It might blow off some of the good shit, but it should also get rid of quite a few of those little buggers. Hell, at this point its worth a try right? How many weeks till harvest? If you still have 5-6, keep with the chili recipe a bit longer man, just make it light. Like I said earlier, I have heard mild soap and water works also, on mites, not sure about the thrips, but i'd like to hear from someone else on the soap and water before saying to go with it. Again you'd wanna keep it to a minimum. I dont know, its a thin line for me between smoking bugs, or smoking soap hehe. Either way, live and learn bro. Make the best of what you have grown though
