Hey all, Anyone used these before? Looking to invest in some insect predators to clean out some aphids. Last year I tried lady bugs and predator mites which pretty much died within a few weeks.

Hi crew just a question for anyone who may know, I have a female white widow that has been flowering for 67 days in cupboard, scog perlite/coco medium. Having chopped main colas at day 63 when trich's were creamy just as I prefer, I placed the plant back in flower cupboard after being in darkness for a cpl of days to see what would happen. It appears to have started to self seed. I can't see any bananas, though I have had this plant throw bananas this late on other grows. I will try to get some happy snaps up. My question is will the seeds be hermi or wishfull thinking viable seeds, or should I just pull her out to stop the risk of crossing with a sativa that's about two…

Went and had a look at my girls, and on of my Berrys is showing wired burning on the tips. I thought it might be a Nues issues but cant find anything that it might be. Could it be heat stress, it is only showing on one of my girls.

Hey, I've got an auto star ryder and a "the ultimate" under CFL's in a cabinet. They spent their first 5 weeks or so outside in the rain and I noticed these flies (I think they're "Dolichopodid Flies") on them occasionally & wasn't too concerned. Once I put them in the cabinet the fly population seemed to increase dramatically. The other day I noticed the same white spots appearing which I got on my last grow due to spider mites. I used the same formula (which worked last time) it seems to be killing the flys off faster but the white spots are increasing aswell as some yellow spots and holes. I've read these flies feed on aphids and other pests, could they maybe o…
