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

Co2 correlates with temperature not light conditions. 85-90 degrees F. 1200-1500 ppm co2

We changed the soil instead of the pot
I said to my brother change the pot, but he just changed the soil. I think it was stress. I put it in a place without sun. Do you think should i switch to a 20-liter air-pot, or should I continue like this? Note: She is in the 6 hour dark period right now. Thanks

Timing to Harvest
I thought she would need about 84 days to finish. So that would be in about a week and a half. But as compared to pictures I've seen around here, she looks like she may need more time? Right? I just don't want to start flush early. I'm growing in coco.

Want Dense Buds
Zatanna is drying and smells great but her buds aren't as dense as I would like or thought they would be based on how they felt before harvest. I know light is a big factor it she was in sunlight for most of the grow. What can I do to get nice tight nugs?

Am I within the chop window?
Currently on day 75 of this meph sour stomper. I feel like today is chop day, am I right ? I see mostly cloudy/amber on the calyxes and the leaves are discoloring - despite me not stopping the feed - which seems to indicate she's grabbing all the food she can and near done.

Harvest/Partial Harvest tomorrow, or leave it unattended for 7 days over Christmas?
So let me preface this by saying that I'd LOVE to come home to some dried weed, ready for curing, but I don't want a subpar bud. My original plan was to chop tomorrow before I leave town, but many trichs still look clear (I think), w/ a few amber. Advice? More pix/info in diary!

Germinating
What’s your germination method for autos? I always used water then towel, I’ve only ever done photoperiod plants though. So I’ve gone straight into Medium this time. Is this as successful or is it best in the towels? Thanks growers
