Question about CO2
Idunno, maybe this is a stupid question but...lol
I'm going to set up a DIY CO2 bottle and I've read that you should only inject CO2 when the lights are on, but how do you turn it off? Do you just take the cap off and let the CO2 escape into the room?
Also, I just read that you can add baking soda to the yeast and sugar mixture to help buffer against pH drops. Anyone do that?
