Greetings loved ones! I'm new here as a member but have been following this website religiously for months. I'm hoping to absorb some of the experienced growers wisdom and be the best I can be at growing my own medicine! To keep it short, I want to get rid of the ac unit in my tent (for more plants and much less electricity used) and I was hoping I could do that with my vented 1000 watt hps light, fresh 72-74 degree basement air coming in from the bottom and adding co2 to help cope with the heat. When I first got the tent running without the ac unit it was peaking at about 84 degrees. Recently however I have bought a motorized light mover, (tent is getting full) and this nifty bag of material that claims to naturally produce up to 800 ppm of co2 for up to 6 months. With the ac running, the canopy varies between 72 and 78 degrees throughout the day while the light is on and when it's off it gets down to about 66. How warm can my girls get with added co2 for them to still be able to thrive? If seen a lot of similar post but they don't seem to answer that specific question. Hopefully the light mover spreads the heat out a tad and maybe I can keep it below 84 degrees? Also, if I get a 2nd co2 bag and up it even more would that help? Any and all information is greatly appreciated and if I need to give more info for a more direct answer I'm happy to answer any questions. Thanks in advance and God bless!
