I just got back from the store with my usual predator nematodes and some of that stuff called gnat-nix. I have never tried before but its basicaly those growstones crushed really fine. Since they're made from recycled glass it's supposed to shred em like DE, but it can get wet.
I grow in 100% coco in airpots with multiple feeding per day (DTW) so keeping these fuckers at bay takes vigilance. I don't catch or see many but that's because I am proactive with the nematodes and will step it up if I start catching too many.
My hope is that this is one more tool to keep these fuckers in control. But will continue monthly (or more if needed) nematode applications.
Just a little disclaimer: I don't really grow weed, hell I've never even tried it. My shrink suggested I develop an alter-ego to help with my low self esteem. So I took on the identity of a marijuana grower. Seemed real exciting and a little risque. So if I post any pictures, sorry but they're just something I found on the internet. Thanks in advance for playing along, and helping me with these tough times!
