Diary Infamous Dots

That is still dead BTi with the toxic excretions that kill the larvae. But very concencentrated and cheap enaugh so you may use it with almost every watering without it getting expensive. Aplication rate is so low that you would get hundreds of liters of dilute solution ready to kill the larvae upon contact out of 1 liter of that solution. What I would suggest is search for a smaller comercial size, and use it like once every lifecycle of the fly. (Lifecycle changes with temperature, but it will probably be like once every 10-15 days so that you'll never have problems again)
The product datasheet lists application % both for 1 minute kill on contact and 10 min kill on contact. The more dilute concentration that kills in 10 mins is all you need, beeing it soil, soilless or hydro. It's in milligrams per liter, so very dilute, as I said.
P.s. vectobac wg and vectobac g are powder forms of same product, may be cheaper and last longer. The one you posted is 11% concencentration liquid form, wg is ~35% conc in powder, G is again around 10% concentration but in powder form.

Thank u exploziv! I need to locate my brain and put it back in my head so I can understand what you're saying, because it sounds as though it may be a real solution to FG on my scale..

Sure! Actually, I wish they would sell that or something similar around here! I'd buy a bag of granulated powder and never have problems with those little bastards again in my lifetime.

Dots, wifey and I tried our first wash of bubble hash last night. We are getting a mini washer soon.

Not tried that exact product, but have used various forms of BT, and not convinced it worked that well tbh. I've found nematodes to work best by far ... but not so convenient as you have to buy them fresh.

Got things looking good in here and fuckidity fuk fungus knats. Chug a chug a grow grow.

You have to have BTi, other suspecies not gonna hurt the fungus gnats. Some are used for other insects, but will not harm fungus gnats in any way (unless there is crosscontamination with BTi in the factory). Proper use, as instructed by the producer and also tailored to your specific needs (like taking into account temperature and life cycle and so on) is important as well.
Years of use in organic gardening and pond keeping show it's very effective. That product that dots linked even has application rates that will clean running waters (streams) of larvae. It's that good when used properly.

Thanks, its gnatrol that ive been using which is BTi - but ive just ordered a different brand of it- actual mosquito dunks this time.

Y'all are awesome, I wish I had someone to wash hash with me
Anyways, I'm on to it homie! I'm making an order for a set of the small bags today! I have a big set i used with dry ice but I think bubble is the way to go..
mini washer is a sweet idea mang, I like to watch bubbleman do his thing. Let me know how it turns out, that first pic looks nice n sandy

Good to see u my friend, thanks for the reminder, I meant to swing by your thread last night, see u soon

Yo VG -not saying this applies to you- but in a small scale I think a physical barrier would be the best ie perlite layer..​​​​​​​

Sure!

Thanks again sir

I've used perlite in the past with great success. A 2 cm layer above soil made it easy to get rid of fungus gnats within one life cycle time. But I don't like it because of the health dangers from the dust. I then tried ordering gravel to replace it and they sent me marble gravel instead. That's too chunky and those bastards can go beween the bits, especially on corners. I wish a relatively inert and healthy substitute for perlite would exist for this use.
Now, sorry for the offtopic!
Hope you guys manage to find something that fits your styles. I am lucky and for this run I managed to simply not get them inside. And since it's winter outside, I should be set for a while.

exploziv by all means this thread is open, all discussions welcome..

You know wetting the perlite thoroughly before use makes the dust a non issue.. but maybe you mean it dries in the grow and spreads when disturbed.
I brought a roll of 'weedmat' to cut circles out of and place on the surface with a few rocks to weigh down, but still not really a viable option in a larger grow (if you're lazy like me

Its spring here, and though not warm they are around.. big black ones too, seems I have bred my own mutated species.. there are some factors I could consider, like only recently have I began to bring new bags of coco in, previous I exclusively re-used/re-buffered coco, so maybe I've brought more in..

I've also brought nematodes, put them in the fridge but never used them and im afraid they went out of date

I used to use 'eco-neem' religiously weekly as a drench and foliar.. not anymore (id prefer not to use it, ya know) but I couldn't really say if it had an effect on the gnats because I have so many plants. However I have witnessed it knock gnats out of existence when I used it on a small number of plants in an isolated tent.

Thank you, man. Very welcoming!

Yeah, thats what i meant. Especially my air circulation fans blowing dust from it around.
Honestly I am probably overtinking it and trying too much, but feels stupid to know the dangers and expose myself to them, both pre and post harvest.

A pocket microscope should help you with judging if nematodes still alive. Depends if they run out of food, I guess. Can't be bad to just try them, as well. Worst case they don't work.
But i am kinda lazy as well, so I can understand you. I try to pass the lazyness as inventivity and efficiency in eliminating "unneeded" steps, tho. Don't be lazy, man!
Anyway, ! Time for sleep soon!

Dots, whenever I get fungus gnats I hang those cheap fly strip papers that come in rolls. Like 6 for a dollar.
and then I too add bti. I just grind up mosquito dunks donuts (I never see the bits locally) and sprinkle the dust on the top of each pot. Like 1/8th to 1/4 of the donut. Then I'd try to let the media dry out a little longer than normal for about 5 days.
The ones that don't get stuck in the papers eat the bti and they are gone within 7-10 days.
I used to get them when I was running coco and organic amendments when the soil stayed too wet. But don't really get them now that I'm straight coco and perilite, and I keep the media wet. 5 watering events a day

First step in the battle against a pest is usually researching the way it feeds and its life cycle.
That way you can find the fastest and most efficient way to battle it.
That being said, adults are just last stage and have no more than a reproductive goal. They will not eat anymore. Happens with a lot of flying insects, most of the short lived ones actually.
So the traps will help you catch an adult and avoid the next generation of fungus gnats in the form of eggs layed in your soil by an adult female. That is still a big win cause they lay many many eggs.
They love moist decaying matter, so the more rich organic matter your soil is the easier they will find it and lay their eggs in it. The eggs that any remaining adults left in soil then hatch and the larvae feed on the roots of your plants, and also the organic matter laced with BTi. BTi is toxic to them and also stops them feeding even before it kills them. So very effective. The adults die of old age after depositing the eggs, which is the last step and also the goal in their fast paced life.
All larvae need to eat to evolve (actually is all they do in that stage, eat and grow) so basically you don't see any new ones cause they don't get to that stage, unless you have untreated soil around for them to do their eating and growing in, get to be flyiers again, and so on.
I'm sure this is boring to many, and I guess it shows I did my research when I had them first time. And also I found a way to combat them after doing the research. With limited things to buy around my location, and certainly nothing natural like BTi available to fight them, it was a layer of perlite at the top of the container, as dots sugested earlier. And it still works, for those that don't fear the dust from perlite is that dangerous. Since then I also learned to research the materials I use as well, and I won't use perlite in a way that it can be dry and "shedding" dust in my growroom, or anywhere near me for that matter. Silicosis is no joke.
CannaRed , sorry for the long post that started from just a sentence you were wrong on. My goal wasn't to show you are wrong, but to spread some knowledge around, since this thread been transformed into the main fungus gnats talk place on IC for the last day or so. (Sorry again, dots)
Man, I did write a lot! Sativas are no joke, either!

gizmo666 no fly spray near the garden please bro.

 

[gizmo666]

gizmo666 no fly spray near the garden please bro.

As said I've only done that twice both times in early veg
I'm not stupid enough I hope to try it on flowering plants
And tbh it did work

This is turning into the fungas gnat thread lols

C4DDF2#3 is on plain water. Smells like death and the garlic onion is on the back now. Pics cannot capture the tric-on-tric coverage. Feeling a little uncomfortable that its being run-out the garden.. ps I use that truncheon for mixing bio-stims, its broken.. pps sorry for the shitty pics

 

[gizmo666]

Very nice
Nothing wrong with the pics

 

[CannaRed]

Yeah I worded that wrong. Thanks for clearing it up

 

[Sampas92]

Are the colas so big that makes the fans look small or indeed the fans are not very big?

Looking delicious mr dots

Peace
