neem oil soil drench?

Put an inch of clean coarse sand on your soil. Fungus gnats can't reach the soil, so any eggs that do get laid, hatch only to starve on the sand! (If you use beach sand, wash it well first! Cannabis is not fond of salt.) The easiest way to wash sand, is to go out on the lawn, half fill a 5 gallon bucket with sand, and stick a running hose in it. The dirt will be washed away in the over flow. Just push the hose up and down through the sand. It can be kinda fun to do if you're stoned! :D

A nice little plus, if you use white sand, light will be reflected back up to the plant! A couple of sticky traps will get the adults.

And I don't know about your brand of neem, but mine STUNK! Clean sand doesn't smell bad!- Granny:hippy:

Now that's a good idea! Thanks Storm, I plan to use that method as that makes perfect sense. And I'm with you on not caring for the odor of neem oil - tis funky, and not in the good way.

Win win. :)

thanks for all the great suggestions...

it's been a few days and the problem is waaaaay better now.
pretty much solved.

I let things dry out a little, been being more conservative w/the watering and increased the ventilation....

and I agree, neem oil stinks like really nasty peanut butter haha :rastasmoke:

i have used Neem in the soil with no ill effect and killed every flying sucking rat around ,mix as directed even less if you are worried sprayt soil ever couple of days til bugs are dead.Neem is systemic.

oh i have tried every thing to kill all sorts of dope chewing rat bug around Neem in the dirt is best, or sprayed under the leaves.neem residue is pretty minor compared to bugs.

Just reading this thread...I use "mosquito dunks" (home depot, around 10 bucks, available online) they are a kind of bacteria that kills the fungus gnat larvae and is harmless to everything else, impossible to over or under dose. Just put a little chunk in the soil and it reproduces...I haven't seen a fungus gnat since. Aslo available as "Gnatrol" but more expensive, same bacteria.

the dunks do work real well.
i like the smell of neem oil...

Additional advantage of using neem in the soil (during veg only) is that the plant actually will uptake enough to keep bugs off, in particular spider mites and the season is just starting for them.

Look at What's his name's bible and he has a dose in there I think, not available to me at this point.

im three weeks into flower could i still drench with neem or spray on soil? why is it not recomended for flower? if it makes the bud smell or taste like neem i will definently not try it but i got gnats n they are making a come back from almost nothing after i put up traps now the canopy is thick and the traps arnt working as well. the yellow traps suck ass theyve caught like 5 those really cheap spirally ones work alot better but will grab onto anything and everything if they are hangin around in close quarters.
anyway should i use neem?? i dont have alota money for products n i already have it

REAL spider mites DO have web. False spider mites don't. The web is the reason they're called spider mites. And yes neem works for them and gnats but you need to you it every 3 days for 2 or 3 weeks to tollaly get rid of infestation.
