Just had a fungus gnat issue. Diatomaceous earth sprinkled on the soil killed 90% of them. Good luck!

Not sure how this will help you know. But Iām using a supersoil, and put a 1/4ā layer of sand on the bottom. No gnat issue so far

Throw in a Hot Shot pest strip overnight and wake up to dead gnats. š¤š¤

hi, i use to leave 1 inch perlite layer on the top of the soil. this will prevent new gnats to get out and go to reproduce. you can also put a potato slice in each pot and change it every 2.3 days. gnats will go to reproduce in it cheers

Pest control looks like fungus gnats and larvae
Ever since this grow i noticed fungus gnats flying around. I always put sticky traps down and would catch an adult every so often but always saw tons of little dots I thought was dust or fabric until I used my scope. I bought a product gnatrol and will try it. any suggestions

Bug control info needed for outdoors
Could you please suggest some safe bug killer powders or solutions for Cannabis plants growing outdoors. I have not found the bugs that are making little round holes in the leaves. No aphids or spider mites visible. I live on east coast of Canada, if that information is helpful.

I planted an extra stain but decided not to record it. I planted it the exact same time as my Polar Express, so it's 15 weeks in the ground. It's called Trans Siberian and I'm just wondering how long it might have left until harvest.

Dodgy grub?
I think these guys are living in my soil. I'm assuming they eat vegetable matter. So are they bad? Is there a way to get rid of them or just start again with new soil?

One of these phenos isn't flowering (9 weeks in veg). Is it possible that the autoflower trait wasn't passed down? I won't have a 12/12 environment to test it for some time. Should I just trash it?

Silverfish
I found a silverfish (is this the correct name?) in the soil of a plant; obviously I immediately threw it out and checked if there were others by moving the ground a little, but how do I make sure I make them disappear? or do you know if they can be harmful to the plant? š

My plant is short and wide and the center is pretty crowded with leaves but they are all starting to produce trichomes. Is it an issue to have leaves touching each other in this state or do I have to remove some? I don't really want to mess with her in this stage.
