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

Rats on the farmI live on a farm and there are rats that run around in the night.
Atm I'm moving my girl outside in the day 6am - 5pm, then inside for 4hrs of darkness, then under lights from 9pm - 6am. Repeat.
The plan is to leave her outside 24hrs when flowering. Will the rats get her?Week 1

Shes bushy and harder to LST for air flow/light to the lower sites. The larger leaves are laying on the top of the bucket, and there's moisture when lifted. I'm using a larger fan to keep air moving. Do you recommend trimming some leaves during veg? Also which leaves would I cut?Week 4

I lucked out, it's female of a landrace wild-collected Sativa from West Africa. The plant has entered the pre-flowering stage on a 13/11 but is still somewhat small due to stress inflicted by my beginner's mistakes in earlier phases. Will she grow more? Should I just clone her?Week 7
