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

Does it go against community standards to inbox someone who replied to a grow question? 280 characters isn't enough to describe all problems. There are so many experienced growers here that if we could actually talk back and forth it would be so helpful but I can't figure out howWeek 7

mineral wool "turns green"Over time, the top layer of mineral wool "turns green". The problem is probably that the humidifier is located too close to the plant.
I don't know.... to close the substrate from entering the light ?!
What do you think ?

Totally random question.Random question... When do you start day 1? Is it the day the seed germinates? The day the seed pops above ground? The day the girls have enough leaves for nutes and a regular environment? Just broadening my knowledge. Thanks, guys!Week 4

Gonna put in 5 Autoflowers in this tent (12/12) for at least 1 week (to gain time). 20/4 after.
Do you guys think it will have any noticble effect on the yield in the end?
What you think about 1½ weeks? I would imagine that's the limit.
Interested to hear your thoughts… Show moreWeek 9

Are these males?Are these clones turned male? I cannot tell. They are clones from nice well established mom. They are, and have been very weak and not really doing much for weeks as I've paid much more attention to mom. Should I ax these? Don't have seed room.

Should I switch to larger pots for flower?Should I switch these girls to bigger pots for flower? They are in 5 gallons. I have 30’s I could put them in or will it be a waste because they aren’t so big yet?
I’m assuming we start flower in about 10 days (not scientific lol just best guess)😎5y ago
