Generally only use co2 if you're using HPS bulbs because of the amount of heat stress they put your plants under.

I upload photos taken with a microscope to show tricomes maturation.
This is the hardest thing for me, because I suck with colours, to hold the microscope still.

Letting the pot sit on runoff water.I've been letting the runoff on the little plates below on the pot.
I've read yesterday that it was a bad idea and i should remove the runoff and let plates dry.
So just to confirm.
I shouldn't let the plants sit on the runoff water? Correct?
Maybe this been causing my probs.Week 4

Counting flowering weeks according to breeders estimated harvest timeAt week 9 from flipping to 12-12... I read to not count the first week or 2 tho.. Because she technically isn't flowering just yet.. Not till you see the pistils.. And can't miss the beginning of the flower stretch... So that would really put her at week 7 or 8 flower?? Help lol.Week 14
