Ballast hit nail right smack on the head. Either do it correctly, or dont do it at all.

Pseudo C02 setups (mixing whatever and whatever) are about as useless as tits on a fish.

I built my room originally to use C02 (sealed air tight, duct dampers, etc), but my yield/watt I get now is fine for my purposes. Plus no tanks or burners that scare the shit out of me to fool with.

Check out how the big boys grow that use C02. You will see perfect setups with everything installed CORRECTLY. Not makeshift ghetto setups trying to spray seltzer water or what the fuck ever on plants to give a C02 boost.

If you smoke 3 ounces a day, grow plants in 5 gallon buckets or something. But before you ever consider C02, I am going to make a wild guess and say there are 150 other things you need to dial in first. Like growing your first plant.

Keep mothers and grow from clones. Thats the ticket for 95% of growers. Got one veggin while one is flowering. Down time is minimal when you do it right. Even that takes a few grows to get your timing perfected.

Well, thats my :twocents: on C02.

Keepin it green,
