CO2 Help

I dont think co2 is worth the cost and headache unless you're running a large scale grow op with 100% sealed and controlled environment. It's like icing on the cake after you have everything perfect. You can grow fat delicious buds without it

Unless you are growing in a closed/sealed system, co2 is largely a waste as your fans will remove nearly all of it before the plants can make any use out of it. Save your money and concentrate on your care routine instead.

1 should I be doing the same? no, c02 is mostly wasted on home grows unless you are pro and maxing out all your other environmental variables. VPD, PPFD/DIL, RH, TEMPS,FEED It also needs a space that's not always venting or its just being tossed out. Its a easy cost to save yourself so don't do it. 2.can I make this bag myself with mushroom? yes, but you need the correct mycelium culture/spore syringe and some understanding of how to grow mushrooms and the process of getting everything ready to avoid contamination. Next question is should I add Co2 into the tent via a tank??? no, see point one. There is enough ambient co2 in the air to do most things, and indoor spaces have more co2 then outside because we are in them generating lots of it. Good Luck!
