Gnats! Wanna sterilize soil

[compassionateExotic]

Let me ask you this lol - any issue using this stuff in flower and or up to harvest? Lol

Only reason I ask is I know some people like to flush their soil before harvest (I do not personally) but is there any chance that the roots take this stuff up onto the plants?

Maybe I’m just being paranoid lol

U are just being paranoid, BTI is just a beneficial bacteria and def isn’t a harm to you or ur plants end results.

flushing is also just paranoid and non ag/logical reasons. Only reason anyone would need to “flush” was way over feeding and they were reusu(ng their medium and knew it had too much salts/metals ( if u were reusing u wouldn’t be doing that in first place )

Yea OP let me say Im dtw coco and Im at war with the gnats. Lost 6 of 8oz in one plant, they must of caused it. Brown roots. White roots in the uneffected.

FML I thought gnats were a summer thing. Better buckle up lol I just started using the bits correctly. Hope that works. Bought 120oz of it.

Nice thread, Ill have to check out the liquid bti.

I can't believe fungus gnats would cause that much damage, you sure they're not root aphids?

They infested my mother cabinet, keep releasing adults and they got into the other tent but that doesnt happen super easy but it did.

I only put one nug of bti in each corner being dumb misreading the instructions. As I keep studying the matter I learn new things, I guess it will take 3 weeks to see it work.

No other bugs visible. I didnt think gnats could do this but quickly found they do. Hundreds of them munching on the roots surely can. And other parhogens etc naturally hitch hiking.

I've never seen/heard of gnats doing anything that serious. You might wanna check to make sure they're not root aphids, the mature flying ones look very similar to fungus gnats

One way to tell them apart is by their wings - gnats hold their wings horizontal when at rest, winged aphids hold theirs vertically like a sail

Good luck! Hopefully you're right and the BTI knocks them out! It's always worked for me with fungus gnats...

Shit, good looking out, some do appear sail boat. Shoot.

Idk actually I just saw live ones and they dont have sail wings. Could have both.

Hard to tell on a sticky card, the ones I can discern on there definitely have long bodies like gnats tho

Microbe lift bti. Simple,cheap,effective. Sticky traps for the few remaining Speedy Gonzalez's that linger until repeated applications does it.

Fungus gnats have a longer thorax, and root aphids have those twin tailpipes, stubbier body.
Wing length vs body length is another way to sort them.

Leaving soil to eliminate gnats is a fallacy. Trust me, I did just that - went 100% back to water culture hydro for a bit. Started great with massive bushy white root system till the gnats decided it would be a great place to set up shop.
Hydro is not exempt from gnat pressure.
Cover the top of your soil in the fabric pots with landscape weed block fabric and sand or fine rock. I've been using chick grit. Gnat problem handled
