I can tolerate the odd fungus gnat when all my plants are well established, but I've got seedlings going at the moment and feel that they are more susceptible to their roots being attacked by the larvae.Hope the nematodes work. I have fungus gnats again myself and I've placed an order for some. They sprang up in my flowering room, one or two occasionally in the veg room.
Thanks for the concern, the thrip in this tent are actually the least of my worries. I've been working quite a distance away recently so apart from being a little absent and neglectful, I've made a couple of school-boy errors in my main tent. When I flipped to 12-12, the girls were showing a little mag def, and I usually do some kind of cal/phos foliar at this stage. So, I gave them a foliar of home made cal/phos with some epsom salts mixed in. On top of this I had recently increased the wattage on my lighting without fully compensating on extraction and not having the time to monitor it................The result, quite a few fried leaves and I mean serious burn, a mixture of nute burn and heat stress, not good!!!............it seems I'm gonna have to make a quite few of the same mistakes as I did as a hydro noob all over again. LOLHope you get it all figgered out.
Fingers crossed the nematodes get em!These are 30 days since flipping to 12/12, they were heavily infested with thrip and have lost a lot of their lower leaves. I do think the thrip have effected bud growth as well, they started flowering really fast and sort of stalled when I noticed the thrip population exploding, despite IPM measures and predator mites being used.

These aren't the worst affected leaves, they're probably about average, I've given them one treatment of nematode, which I don't think the plants liked, I had to be a little rough with them to get right inside with the sprayer though. They'll be getting another 2 treatments over the next two weeks. I've never foliared with anything during flowering before, but I've never had an infestation like this.

Cheers bro, they are starting to look like they're starting to fill out again and I can't see any thrip ATM, they're still gonna get at least one more nematode spray though, the last one didn't do to much harmFingers crossed the nematodes get em!
I sat a while admiring the structure of your plants - they're lovely elsewise!
Wow, impressive footage there!This is what I'm up against, I took this vid a couple of hours after the 2nd application of nematode
Looks like I'm gonna have to try a different method, maybe some lacewing larva or something IDK
I'm currently having a coffee and spliff break after spraying and watering everything down to get moisture levels up in preparation for another application of nematode. This will be the last one though, I've got a few different predatory mites on the way to hopefully take care of any stragglersWow, impressive footage there!
Not sure you should give up on the nematodes too soon though -- these parasitic nematodes need to find their prey (the thrips) to get at them, so maybe you just need a few applications for them to really get going on them?
Fingers crossed!
Wow cool -- the ones in the 1st 2 vids, looks like they're bacterial feeders? They look like they're vacuuming hahaMore micro movies......... some of the millions of nematode I've just released and a young thrip, not one bit bothered LOL. you can also see some of the thrip eggs, I need something that eats these eggs
