Hi all,
Just as the title says. I've researched and it seems there are lots of differing opinions/info regarding when to use CO2. I would like to get ICMAG community's thoughts on this topic. Thanks!

Co2 is overrated for the home grower, and not really needed unless you have a closed environment. If you have a lot of light and max your environment with top yields then adding co2 can help.

The best time for co2 is during the bloom, you can reduce the time it takes to produce flowers. It's most important to add CO2 in the first 2 – 3 weeks of bloom when flower production starts. During flowering, the extra CO2 can help maximize high-intensity discharge lighting. Thanks for the post.
