My Version of Brewer's Yeast CO2 Generator 4 Clones: PICS INSIDE

Here's my version. It's simple, and needs only a plastic 5 gallon water cooler jug, air pump w/ airstone (not critical, but provides for more vital yeast growth), cap, 2 packages for brewer's yeast, and about 6 feet of 1/2" ID tubing. I also use an aquarium chlorine/chloramine eliminator for treating tap water, or you could use RO or bottled water instead.

I fill the jug w/ 4 gallons of water, add sugar, and bubble for about 30-45 minutes to maximize oxygen; not required, but makes for more vital yeast growth.








Suspend the yeast according to package directions. If you used the chlorine/chloramine eliminator, add a drop or two to the water you suspend the yeast in:







After yeast rest in water for required time, add to the jug and affix the cap. Caps can be ordered from any homebrewing supply house such as Northern Brewer :








Attach hose to jug and feed the other end into the humidity dome through a vent: Voila !

why? not needed for rooting.

No photosynthesis during rooting? Know there's not much veg growth happening, but they won't root in the dark will they?

actually they need very little light to root, i dont have a dedicated cloner light. the plant slows down and all energy is put into making roots, it's number one priority.

Hmmm, OK. Had a hunch it might be overkill; all the stuff was leftover from beer brewing so thought I'd give it a go. Appreciate the reply.

I think that this is overkill...great for a cheap co2 system for growing...but rooting?...

One added benefit; the fermentation kept the moisture levels very high inside the dome. Didn't need to spray for about 48 hours, but that's not enough reason to do it again.

Maybe I'll try venting my hot water heater into the room, eh?

seriously, have you read that thread where the dude is actually DOING it?

a full tank of co2 can be more deadly than a water heater exhuast. I don't know why people freak out about it, non-vented small appliances that burn natural gas and propane are approved for use indoors.

yes, i have. and as a big diy'er(i like to build all i can) i think it is a terrible idea. to each his own.

wrong. wrong. wrong. a co2 tank will not put out co, which is much worse than co2 in much lower levels.

Yeah, I've had a bit of carbon monoxide poisoning and its not nice. Mine was just from a faulty car exhaust.

very small amounts. tiny amounts.

why do you think they allow non-vented small appliances (up to 10000 btu) to be approved for indoor use? I'm not saying I do this but I know someone that did and hey, they're still alive.

numbers to back it. http://www.inspectapedia.com/plumbing/Gas_Combustion_Products.htm
