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

Auto flower?Out of all my plants only the one of them has really shown this much progression with flowering sites. Is it flowering already before I switched the lights? If so does that make it an auto flower? Also will it hurt my plant to have not changed to 12-12 yet?

General Question - How Do You Make Your Diaries?I plan to make a new diary for my outdoor grow this year after I skipped last season. Just generally curious, do you enjoy making a separate diary for each plant, or do you prefer making 1 diary with all your plants? Looking forward to the grow season! Cheers!Other. General questions

Are these ladies ready or should I give them more time?Flowering time is said to be 60-70 days, today is day 62. I've seen a lot on the trichomes and when to harvest but I don't quite have the eye for it yet as it's my first time. Would you guys say these are ready or should I go a few more days. Thanks in advance for any help!
