First thing I tried was a product from grow shop called Gnat Off - didn't work and v.expensive considering. Have tried the stick pads and got quite a lot of them, have them up on the ceiling and will carry on. They must be living off something, how much damage do they do? Are they a serious problem? Should I just use that systemic pesticide stuff and say goodbye for good?
BTW while on the subject of coco, I use cannazym and reuse the pots. this is 3rd time round, how many times can you reuse the coco with zym b4 you have to replace it?
Psi Reviewed by Psi on . Little flies on coco Using coco with run to waste. Have noticed these small flies that seem to run round the rims of the pots. Put up sticky pads and caught quite a few around the ceiling. Looked at them with a glass and they are small and black with wings, long and thin about 1mm long. Cant notice any damage on leaves or anything much underneath. Had them for a few months now. Been offered soem systemic spray that is pretty nasty stuff that will do the job but am in 4th week of flower so am reluctant to spray Rating: 5
