Thrips

Cucumeris is the last one I tried. Might give the swirski a go.

Are you sure you have thrips then?

Also Cucumeris need 50% humidity or higher and nice balmy temps to thrive, any lower and they die off, maybe that's it?

Also if your thrips are full blown adults, it takes 3-4 weeks to see results.

These are the ones I bought

Yea I had humidity issues when they arrived. Already thought my environment wasn't prime for em after that.

Yea they're thrips. Hundy. Got hit with those and root aphids same time. Thrips are still here.

I think the other thing I need to do is when the autos are done in the living soil box is just cut all the cover crop. Gonna be a shame to cut down the massive miniature marigold.

Ya think spinosad will kill cucumeris? That's another thought I had.

Yes, you can't spray and use them, I get a lecture at the grow store every purchase lol

You can hit your plants with spinosad a few days before you release the mites. Double trouble.

I've had good success with them myself.

swirski mite - Amblyseius swirskii Athias-Henriot

They live on the foliage:

Ok thanks!
Hypoaspis are the ones people usually recommend which are a waste of money for controlling thrips.

Predators are preventive measure not a cure for a thrips invasion.

Agreed, however if you spot thrips around week-5 of flowering, predators will slow them down and help you finish the cycle without going nuclear on them.

The thought of thrips scares me.

There's various mite species that go up into foliage.

I've looked at sulphur. I might be remembering wrong but can that be used in tent with plants indoors? It's like a more powerful hotshot no pest strip right?

It's been years since I used it, at the time I looked into pest control for edibles and apparently sulphur is the one.

So I could use my little half gallon pressure sprayer and just go to town with some sulfur, but burning sulfur indoors may be a bad idea. Specially since I actually have a newborn in the house, too.

The problem with predatory mites is that they live in the soil and thrips do damage up on the leafs.

It's like a cane toad scenario lol.

I got rid of them with sulphur smoke bombs, 1 every 3 days x 3 to break/kill the egg larvae adult cycle.

a quick search...

You need to use more than soil bugs
Swirskis and Cucumeris flies take care of leaf and stem and flyers.

Yes it's bad news to be breathing any fumes, when i was lighting one i caught a just a waft of it and had real headaches from it.

I'm not sure about spraying it directly, I've only used versions like the sulphur candles with a touch paper.

If you check out using a sulphur hot box you might pick up some useful tips.

I'll check it out. I've got a window next to the tent. Suppose I could always vent out there with a candle.

From reading. It looks like spraying wettable sulfur might hit them for good. Just not within 2 weeks of spraying oil.

I use 1 tsp per 16 Oz of water. You can find it in the canning section of most grocery stores.

I'm assuming this is totally safe to use through flower.

If need be, but the idea is to control ipm in veg, so hopefully there's no issue in flower.

Ya, but it'll burn the pistils.

I'm running perpetual. I can always stick to spinosad for what's flowering and use citric acid or the sulphur for the other half in veg.

I wouldn't spray buds with spinosad.
