Fungus gnats like fungus (molding organics in the soil). Since you are in perlite hempy, the only organics below the surface are the roots. Are you sure everything is okay there?
i have plugs. that is exactly how i do this. you described my method to a T.
i generally let them soak closer to 20 min when i flush. i use 29% h202 at 1ml to 1L for a normal flush. i went 2ml / L for the last flush to get the larvae, and have added h202 at 1ml / L to the feeds since
in fact i use a plug for every feed / water as well. kind of a flood and drain hempy lol
perlite is supposed to do the same. the plant deepest in the media was the the worst infection so far, which was really odd. it seems mostly clear now, i am having trouble with others. really should get some pics.
it doesn't help that we have a yearly fruit fly explosion amongst other things at this time as well

yes, i just got fruit flies too, but none in any tents yet. they make my skin crawl i hate them so much.
no. things are not ok. frickin fungus gnat larvae are munching on the roots lolFungus gnats like fungus (molding organics in the soil). Since you are in perlite hempy, the only organics below the surface are the roots. Are you sure everything is okay there?
i see your thinking tho. good pick up blu
the h202 regimen could also be clearing a root rot issue too. idea being the root trouble gave the gnats some place to get hold.
that is one of the reasons i went that route. i'm gonna keep running it, maybe even for the duration.
i'm hitting it with a btk spray right now. on top of the media and some on the plants.
put out some shot glasses with a little beer, a couple drops of dish washing liquid, and a bit of water. catches the worst of them. it gets a few of the gnats too, but mostly on color.
For fruit flies I make a couple of those 2 liter bottle fruit fly traps. They work really quite well.
Are you talking multiple plants here? Are they in veg or flowering? I am old and probably did read that but forget and am lazy and don't want to go back. But if they are plant in veg how about this...….. Pull the whole root ball, perlite and all out of the container and cut off the bottom 3 inches of roots and perlite. Put 3 inches of fresh, clean, rinsed perlite on the bottom of the pot and drop the plant back in.
I wouldn't suggest that for a flowering plant.
i make smaller ones, same principle.
the shot glasses are preemptive ... i add bottle traps if it escalates
make wasp traps from the 2L bottles.
in veg. over veg now.
trying to clear it before moving to flower.
i have a separate ( really really separate ) flower space that is clear. i'm intent on keeping it that way.
oops - forgot to say hmmm ... i like that. i am not averse to such direct intervention.
My suggestion might seem radical. But look what happened to @Van Stank who had the fungus gnats in his roots. He lost his entire grow pretty much. These plants are amazingly resilient and bounce back from many things. I'm thinking they have a MUCH better chance of growing more roots down into the bottom of the pot then they do surviving a full on fungus gnat larvae attack. Maybe try it with one plant and see how it goes?
i just can't believe they survived the h202 onslaught.
seriously the stuff was bubbling in the pots. my master kush plant clawed right after, but it's been much better.
i'll finish spraying and get a pic
edit : i hope i didn't offend @FelipeBlu . just realized it doesn't quite read the same as it sounded in my head

No problemo, Amigo!

From experience with Hempy, gnats, and mites, I’d highly suggest grabbing a ‘No Pest Strip’ by Hotshot from your local Lowe’s/HomeDepot ($6). You’ll be rid of the bug issues within about 2-3 days. Then just remove and ziplock the no pest strip and save it for another occasion.
These are some seriously mutant gnats - to thrive in such a flood of H2O2!
Another thing you can try is what my brother @BTzGrow did when he had an issue with a non-draining perlite. He used the @SweetSue technique of plugging the hole, flooding until the plant floats, give it a swish and a pull, and out it comes. He then rinsed off as much of the smallish, offending perlite, and repotted in fresh, larger perlite. His SLH plants, which were in flower BTW, are doing quite well.

even more hmmm
i really just wanna flip these and get what ever. these were clones. they are super beat.
i'm going back to seed after. so the drastic re- pot is tracking upward.
if i had a real space i'd up-pot in a heart beat

summer hempy harvest
I’m so sorry I missed this bluter. Well done buckaroo!
Reading over the report on the fungus gnats hurt me.
Of all the suggestions I like the idea of the HotShot trap the most, for speed and effectiveness. Good luck. Remember the DDA I grew that was so stunted next to its sister and when I did the rootopsie we learned it had root rot? Are you reusing perlite? That’s what got me with that DDA - organic root matter left behind that was large enough to give the rot a place to grow.
I learned to clean better. Lol!
Clones cause so much grief we often wonder why we go there, eh?

I'd love to get off of clones, but seeds are so expensive. might try Dr. Seeds, you can get 15 seeds for like $100

I was recommended to this thread for advice or guidance based on experience with hempys that use megacrop nutes and vermiculite medium... please give advise, guidance based on experience. Thanks.
Nutrients:
(MC) Mega Crop Nutrients (9-6-17)
(BE) Bud Explosion (0-19-39)
(SC) Sweet Candy (0-0-16)
Grow size: 3Gal Hempy
Growing Medium: Pearlite/Vermiculite 50/50 Mix
All nutes below have been mixed into 4 Liters of water, then feed to the plant over the course of 7 days. Each "week" listed is exactly what ive actually done for that week.
Week 1 = (1 tsp MC) + (1 tsp Calmag) in 4L water
Week 2 = (2 tsp MC) + (1 tsp Calmag) in 4L water
Week 3 = (2 tsp MC) + (2 tsp Calmag) in 4L water
Week 4 = (1 tsp MC) + (1 tsp BE) + (1 tsp Calmag) in 4L water
My plant looks great, nothing is wrong with it. Just recently showed signes of not getting enough N. Other then that shes happy.
Some people had been concerned with the amouts of nutes I have givein to the plant... plant is in first 10 days of flowering.
Has anyone seem to find if vermiculite blocks the uptake of nutes when mixed at 50/50 with perlite??

In my experience, using that high a proportion of vermiculite is unnecessary, unless you live in the desert (very low humidity). Otherwise, you may experience issues with slow draining. IMO, good drainage, and the ability to water frequently, is more important than minor adjustments to nutrients.

I used them when I got spider mites. I took great pleasure watching them all crawl out and die over a matter of a couple days.
