Howdy ladies & genitalmen, I'm jumpin' back on here in hopes of getting the experienced & wise to share/divulge some of their experience & wisdom with me. 1st off I have a gorgeous, stinky, gooey monster cropped clone plant (sheez, mouthful of a title!) moving right along into 12/12 with no immediate problems showing...maybe a bit of a calcium def./slight ph imbalance but nothing that is seriously damaging the plant currently. I'll show a couple pics just because I'd LOVE to hear from anyone who has grown such a beast! Specifically one taken from its flowering mother far into 12/12, grown to a decent height/width and then flowered WITHOUT topping, fimming, or any sort of lst.

2nd and most important is GETTING RID (or at least getting a handle on!) of a seemingly serious fungus gnat infestation! The reason for the volume of these little bastards in my grow room is the organic super soil/diy compost I planted it in...they laid a zillion eggs in the compost while it was doing its business outside and now even though I wait to water until the 1st couple inches of soil are BONE dry...they still persist...and IN BIG NUMBERS! Doea anyone think their little pre-flying maggott larvae could/are currently causing any serious damage to my roots? Thanks people, ANY helpful input is GREATLY appreciated!

I use nano bugs from start to finish in my grow, as soon as they hit the peat mix they get the pop poppers.

The adults are not a big problem other then them sticking to the buds n dying every where. The flying one don't hurt the plant, but there baby's is what's hurting your root zone. Use the yellow stick cards close to the soil and a few hanging around. This will help stop more eggs being laid, the nano bugs will hunt out the baby's n eat them, n not harm your plants.

This is why I don't reuse medium or once a bag is open it stays inside.

Keeping your soil to wet is good conditions for the pests, letting it dry a little between watering helps also. I run 45% perlite in my Medium to help drainage & aeration, as peat holds a lot of water .

I have had good results by adding BT to the water. Kills those babies at the source.

Then you kill the one remaining adult generation of flyer's and grow away.

Hydrogen peroxide 3% from your local chemist/pharmacy, will kill gnat larvae & is harmless to your crop.. and use yellow strips/& or fly spray- ( don't spray near your plants)- for the adult gnats .. Good luck

This, once I added the liquid BT along with existing sticky traps, gnats disappeared.

BT, I use the "bits" and sprinkle some right on top of my soil. water as normal, (not over watering). stocking over the bottom of your planter to block the buggers from nesting in the drain holes. dry the saucers after every water. I tried a few inches of sand on top of the soil and it did the trick for several house plants but seemed to mess with the cannabis (not sure why), but heard perlite can be used, just a few inches on top of your soil.

would that peroxide kill the beneficial Bactria too? op is using a organic soil. if so not a big deal just use some compost tea.

No the hydrogen peroxide turns into harmless water and oxygen after drying up the larvae, I am just finished using it and it's working fine.. I am in organic soil ( make sure it's the 3% hydrogen peroxide mixture. Happy growing
