Simple Fermentation DIY, CO2 producing setup

[sixstring2112]

Really, the problem is that most people who are in the market for a DIY fermentation system are running a micro to mini grow and hence probably have 1. 24/7 ventilation 2. a setup that is infeasible for a major CO2 setup 3. a tight budget 4. (hence) no $$ for a ppm meter. The people with a ppm meter have a tank CO2 system and thus are not making little fermentation vessels. It's a double-edged sword. maybe someday someone will do a real experiment to test this[/QUOTE]
There is another thread by ninja and if you read the whole thing towards the end someone did test this sugar water setup with a meter. it raised the ppm like 300- 400 with all fans off in a bathroom, which i think would be helpfull for plants. to the original op, are you saying to just drill really small holes in the first cap and does water syat in the chamber? if not i'm gunna just glue my tube in therewithout the chamber.

Yeah, I've seen these type of experiments in an enclosed environment, but I have still to see one satisfying my aforementioned parameters--including lots of ventilation. I'm still going to add it to my grow because I certainly don't run the risk of exceeding the 1500 ppm threshold and it certainly cannot do any harm. Thanks for the info tho.

I can't remember who said what about them not working, and someone else said there was no way to get an good test, but that is all incorrect. I did the same set up, just a little different, with the 2 liter outside the closet and the bubbler on the inside but before the holed hose running around the plants. The first week was great and then I wanted to test out the champagne yeast and a six molecule dextrose and or sucrose. I couldn't find one. But what I did find was Munstons Carb tabs. So I just used cane sugar with the champagne yeast and dropped in 40 crushed tabs. The result was the carbonator lasted twice as long with a slightly higher output. Within the two weeks if your output levels drop a bit just drop in some more tabs and back up it goes.
As far a way to test your levels, I found a 100 cc hydroponic syrnge that I use to suck up air around the plants and then use glass Co2 meters I found at the local Hydro store. The entire set up for a two week supply and two testers was only 15 dollars!

I hope this helps someone out there

Victory!

i may be stoned or i just cant wrap my head around this.
someone explain to me if there is holes on both sides of the bubbler how in the world does water stay in there?
wouldnt gravity force it right into the bottle
+rep for answer

 

[gfreeman]

no because theres gases being made inside the bottle, pushing the water up......lol i dont fucking know.

no need for the bubble chamber, also no need to warm up water and sugar. just put water, suger and yeast into any container. shake it vigerously. tube is just used to guide the co2 close to the plants. if useing fresh air no need for this.

I've been reading tons of these DIY fermentation-method CO2 generation threads and unfortunately I have yet to find a before and after ppm reading on a setup with adequate ventilation. I really want to find one.

check this out by desertrat including ppm counts.

#1 co2 enrichment should only be done in a sealed room. otherwise its a waste (and plants deplete co2 at a rate of 100ppm per hr in a sealed room way faster then a fermentation base generator could produce it)
#2 fermentation is by far the worst way to enrich the air with co2 (complete waste of time and money and a big mess, the amount of surgar and yeast needed to keep the air enriched is way more then those 2, 2ltrs, you would need like 10 of those and would have to change them out every 3-4 days)
#3 you could just suck air from out side a window in to you grow area and get more co2 (a 4in. fan and plastic dryer ducting. in most cities the air outside during rush hour reaches a co2 ppm level of 800-1000 . thats am rush and pm rush- air already has 300- 400 ppms of co2 naturally, so you could waste you money on sugar and yeast or just open a window, because thats where your co2 is heading if your not enriching in a sealed room)

these are good points desertrat does have to use a shit load of mix to sustain a ppm over 1000.

however i would add that outside ambient Co2 is around 300ppm whereas ambient Co2 levels within the average home are 600ppm so indoor air has a higher ppm count.

Nice job, if those out there wanted to they could also do this. Make your own beer and when the beer is fermenting put it in your grow room. Two weeks of CO2 and fresh beer afterwards. Nice job though.

Yes your right you don't need the bubbler but its definitely beneficial and totally worth doing, without the bubbler you run the risk of bacteria getting into the bottle which could kill all the yeast, thus stopping the co2 production, not only that but with the bubbler you know exactly when to change the yeast, sugar & water because you can see when it stops bubbling (producing co2). As for not needing to warm it up, your right but on the same token your wrong, a co2 fermentator kept at 80-90*F will produce more co2 that one kept at 55-70*F, its a known fact that warmth accelerates the fermentation process, too much heat and you'll kill off the yeast, just FYI.

wicked! but what about some follow up Info? Did it increase Yield? still wanna build 1

Sheez, here is a good recipe for making co2. Use a 5 gallon bucket an fill one third with sweet feed or crack corn, add a couple bags of sugar an your prefer yeast, really cheap just go down to your local beer store an buy a big bag of yeast! Heat up your water an pour sugar into water, let water cool an add that to your 5 gallon bucket with your crack corn or sweet feed, leave a little room at top an now place couple of teaspoons of yeast to bucket. Place your lid on bucket an have your bubble hole with bubbler place in, about 1 dollar at the beer store. Now when it stops bubbling simply cook the mash add more sugar when done cooking let it cool place your cooked wash or mash back in bucket an put lid back on an place it back in your room, do enough buckets that can suffice your needs on moonshine an your golden!

Now your cooking! You get plenty of Co2 plus a lot of moonshine to boot! If you don't like to drink it or sell it, with the right still (reflux) simply convert your automobile to flex fuel an run your car on it! In fact you can even get a free easy to get federal license that allows you to make up to 10 thousand gallon of fuel this way, keep it legal people!

I know nothing about useing CO2 in a grow

but CO2 tank refils are fairly cheap , Food grade CO2 200lbs tank refill is about 120$, Non food grade would be around 1/3 of that price

Yea, not sure how long that will last an still a waste unless you have a sealed room! I been growing for awhile an still don't have the desire to run a sealed grow room, fresh air is the key!
