Co2 supply for grow tent growing autoflower girl scout cookies?

I have 2 c02 exhale original bags in my closet 3x7 it’s only got 2-3 plants in there at any one time. 1 bag increased average co2 ppm from 350ppm to 800ppm and the second one increased from 800ppm to over 1200ppm it drops when doors are open and if the fans are on high. The bags say they last up to 6 months but I get about 4 months of good production from them. My lights now may not be “intense” enough to really benefit my plants with supplemental c02. But I do notice a growth difference when the bags exhaust and average co2 levels drop below 500ppm. Just my experience with the exhale bags.

Good data points @Freebirdmikes !
The curious may find this thread in their search on co2. I recently turned the bottle on in my micro seedling chamber. The difference in 4 days is noteworthy. I just added blue, and cfl lights in there to get Up the dli for gas. I’m ideling gas at 800ppm, with 82°, and 65%. They are loving it!
Followed @Tophat method of using kelp for foliage spray (one drop in the dehu) :laughing: Gets it done though.

I push my plants with a lot of light. Typically 1,000 PPFD. I’ve found that there are no benefits at higher PPFDs without CO2.

I was a bit skeptical of these “homegrown C02” exhale bags at first, they took a couple days to start producing enough to show on the meter within 2 weeks of hanging they were bumpin the C02 up in the room by nearly 1000pmm :slightly_smiling_face:

This makes for an incredibly important fact when purchasing a light!!! For the smaller scale growers That don’t use c02 some of the commercial grade lights don’t make any sense!

I get there with 3 HLG 135 (LM301b diodes) panels over each plant ran at about 80%.

HLG makes spectacular products, but also spectacular price tags lol
