24 hours of dark best for what? Yes, if growing photoperiod plants you go to 12/12 to stimulate flowering. If growing auotos, stay at 18/6 the entire grow cycle, veg and flowering.

Grow Technique
I have a short tent so the plants shouldn't grow higher than 70cm. What would you recommend to make sure it doesn't grow long? Maybe flowering early?

If this was yours, how would you proceed?
Going into week 6. I just clipped the bad leaves that show in the picture and will be switching to the growing stage. I plan to do the 36 hours of darkness first. Already changed the water and it has the bloom solution instead of the grow solution. What would you do now?

Putting back into veg before pistils and sexual maturity?
Can you veg even after a 12/12 from seed has been in flower room 3 weeks shes just not big enough and would also like to top her so I really am considering it, the reason being is I can't see one pistil yet which means she's not mature, I don't see why it would make a difference

Oops- might have messed up and have wrong lighting???
I might have confused the two strains I’m growing and have been treating a photo period as if it was an auto (18/6). In week 5 lots of preflower but no real top buds formed yet, I’m wondering if I screwed up with too much light. Should I switch to 12/12? Will 18/6 hurt a photo
