i do actually have a treatment going, dish washing soap in small dishes, does much the same thing, helps contain the little devilsfrom the look of the cross you hit a good one. the ppp is one that i have missed out on, i usually like plants that shape, the big chunky skunk type flowers. i do have a question about your setup, how hard it to get to your plant. also for those gnats you can put some cider vinegar out and it attracts them to their death.
now on getting the plant in/out of chamber, that is a little tricky
angle is a little awkward, and getting a bud snagged is a danger
but not too bad on the whole
