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

When an auto still hasn't shown pre-flowers at week 5 or 6, does that mean the entire growth cycle will be longer - or will it simply have that much less time for flowering once it starts doing that?

Hi, this is my first grow and I am trying to make it successfull. Unfortunately my plants are growing very slowly because I made a few mistakes in the first 3 and a half weeks. I think the crucial one was using CFL 250W Bloom light. Do you guys think I can save this grow?

2 part, first I found a few black dots (picture added to this week) which I thought might be pests but didn't move - research says it could be catapiller droppings but can't find any of those - what else could they be? Second I did find a spider chilling assume he's good?

Spider Mite Problem
Spider Mite Problem at week 8. I just realized this problem, a severe spider mite infestation on one plant. I defoliated the plant to get rid of most of them as I thought I can get away with this until the end of the flowering. Any other suggestions are more than welcome!

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?

Aphids found late in flowering
Looking closely at the week 11 photo, you can see aphids on one of the upper leaves. I removed all leaves that had them and gave the plant a light garlic concentrate to discourage further bugs. Should I just harvest now given that Im close to the end anyway? alternative ideas?
