DIY Co2 dispenser

Anyone have experience with diy co2 dispensers? Would like to know how much it increased your yield compared to not using it at all.

You don't need co2 unless you are running a sealed environment
Waste of effort

I have a grow tent with inline fan carbon filter

Yeah...thats not sealed.

I'm not sure about yield the science says yes, but I'm running a 4x4 with fermentation CO2 generator and I can get 900 ppm vented and 1300 ppm unvented with the surrounding room level at 600 ppm. Unvented is not air tight either so it wouldn't be sealed per say.

The point is going to be having the room the tent is in enriched. If you can achieve enriched co2 in the room you can still have a sealed room with grow tent or tents in it.

If your trying to generate co2 the safest way is going to be using a co2 regulator with an actual co2 tank from a brewery supply, welding supply etc OR you can get a liquid propane or natural gas one online or from a local store that burns only until your co2 set point is reached and then it cuts off.

DIY homemade kits probably aren't going to be that effective or safe. I don't personally believe in the spore bags or w/e that seems very gimmicky to me.
