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 I’m using a supersoil, and put a 1/4” 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. 🤘😤

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

The extremely strong sativa phenotype of this plant leads me to believe that flowering should take much more than 12 weeks. Also the environmental conditions didn't help at all. Nitrogen toxicity is another thought... What do you guys think?

What is the right way to place yellow sticky traps?
I'm having some fungus gnats and was planning to begin LST in a couple of days so I can't keep the traps in the pot near the soil like I have them now. What would be the right way to place them to catch the gnats without touching the plant? Thanks!

Rust colored spots on leaves. Please help! Thanks
3 days ago found one tiny leafhopper, haven’t seen any more. Misted the leaves with dish soap and water. Just got Natria Organic Insecticidal Soap, haven’t used because the plants are in dark. Now have rust colored spots on leaves. Is it from leafhoppers, dish soap, other? Thanks

You think topping my plants to early stunted the growth of my plants. I gave my dad(lol he has 40 years of grower cannabis experience) the same seeds mine nearly grew to 3 feet while hes is growing over 8 feet tall.

So I am currently week 5-6 with Crocketts Confidential. I have not been seeing a lot of upward growth, but mostly just bushyness. The plants themselves look happy and healthy to my eye. Any recommendations to get these girls growing upwards?

Growth is twisted. Is it because of Fungus gnats ?
I have fungus gnats (black flies) for less than a week. Temp 29°c, water Ph was at 7 (now 6.5). I didn't think there were so many flies but look at those twisted leaves on 2 plants ! I've put some Diatomaceous Earth yesterday.

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.
