I've been wondering about this, and remembered many people complaining about flower drop while trying to isolate pods using tulle netting. This could give us some answers. I picked some up and am going to give it a shot for the first time. The only reasons I can think of for flower drop in the netting would be heat, or the flowers just didn't self pollinate so they gave up and dropped. Or possibly the lack of morning dew inside the bags. Or maybe the dew hangs out in the bags and doesn't dissipate fast enough. Just thinking out loud here...I will record some temps inside the net bags compared to outside temps once I get some on this weekend, along with flower drop rates as I go. I've never had an issue with flower drop, but you got my gears turning now.
