I just seen your message in my inbox. CO2 set ups aren't as expensive as people think. A good Atlas CO2 controller is $200 + $100 max for 4 ft. tall CO2 tank on fb market place in carbonated fountain beverage section & CO2 valve $50. $25 to fill tank, which lasts for 1 month with 50+ plants. A regular grow tent it'd last 4 grows. It might seem like a lot of money but the results are phenomenal. CO2 makes each leaf 3-4x wider, which allows more surface area to absorb light & wider leaves means more CO2 absorbtion & faster uptake of nutrients & those super wide leaves allow better photosynthesis & speeds up the vegatative stage in the process. Another benefit of CO2, you can use it to freeze blast your buffed plants @ harvest & use a paintbrush to remove all leaves. Leaves are frozen & brittle so 10 minutes per plant deleafing even a huge bushy indica.
@420Master, just seeing this. I’m going to look into when I re-do my set up. I’m not there yet. I need more light surface area. I can’t remember my message to you lol but that is good info. Appreciate it!
As for harvest time, get a handheld microscope camera that attaches to your phone. Zoom up triconones, & when 2/3 are amber colored, & 1/3 are white, harvest right then. This is when THC is as it's highest
