Any point to adding brown sugar/yeast CO2 "generator" in a grow tent?

[jimmyweedy]

Hi all,

Total rookie question, preparing for my first grow.

Setup will be a 4x4 grow tent with 600w MH/HPS. Is there any point in adding some DIY CO2 solution in there, considering the tent is not sealed and will be properly ventilated (cooled reflector with separate ducting from regular exhaust, clip fan to move air around etc)?

I don't see any point in using one of those $200+ CO2 generators, since the grow tent is not sealed, but will adding that brown sugar&yeast workaround bring anything valuable/noticeable to the table?

The grow tent will be placed in a very well ventilated room (window open almost 24/7), so I don't imagine I'm gonna pass out for good just from the CO2 produced by 1 or 2 bottles of brown sugar/yeast/water that's being ventilated outside the grow tent. Don't sleep in that room either.

If I had to guess, I'd say the answer is "no point", but since the solution is very cheap and easy to make (and should provide some additional CO2 in there), I thought I'd just ask to make sure.

Thank you!

It'll be good for complicating things, and keepin a fella extra busy during his rookie year. Go for it, whew!!

I'm not sure there's any benefit to using brown sugar.

I use the cheapest sugar I can find.

e.g. 2 gallons warm water, 4 pounds cheapo sugar, 4 tablespoons Active Dry Yeast (much cheaper in bulk), 1/2 teaspoon champagne yeast.

The fermentation creates CO2 & alcohol. The alcohol kills the yeast. The champagne yeast can handle a higher alcohol.

Just sits there and bubbles like CRAZY for about 3 days.

The one time I did the math / stoichiometry, it was, about as much CO2 is created as sugar was used. e.g. 2 pounds.

The CO2 goes up the chimney/ air output. But it can make up for a host of sins, e.g. a Veg Room with no ventilation.


With good ventilation ... let's just say, I suggest trying it once.

One thing to watch out for ==> YEAST INFECTIONS, on the grow media.

Thanks for the input! I'm gonna give it some thought and decide when the time comes if it's worth the trouble.

Cheers & happy growing!

Tbh mate if your environment is good (airflow nd temp)
Id stear clear of anything apart from the basics till u hit atleast 0.8gpw

This is definitely a less is more type of situation

Oh just a quick add

DO NOT EXPECT KG'S FROM YOUR FIRST TRY

CO2 is heavier than air. If possible set up your tent where it is easier to collect ambient CO2. Grow in the basement of a gas heated house etc.

No option for that, I live in an apartment building.

And I'm only growing it for myself and gf, no commercial angle of any kind. I'm just sick of getting the same old bs dead-couchlock indica every single "dealer" has where I live. Overpriced, shit quality, opposite effect of what I'm looking for etc. So if I manage to get 300g of decent quality sativa out of my first grow, I'll be more than happy.

Peace!

Why bother

Yeah man, those homemade co2 setups always struck me as gimmicky. You will definitely want to focus on the basics first as far as nutrient deficiencies/toxicities, pest identification and management, plant training, watering. co2 is so low on the priorities list and I think it would be more of a hazard of some nasty shit to spill over, smell weird, make a mess, and possibly attract and encourage pests. It's more common for a first time grower to overly love their plants, even love them to death (literally!).

I was told by others with my experience than I have several years back to focus on the big picture, master all the other things I mentioned earlier, and ONLY when you've successfully maxed out everything else will you be ready to utilize co2.

The first time I used yeast for co2, the gutters and pipes feeding it, filled with dough.

Second time was for cuts, and the blocks filled

Third time was cuts in coco, thinking the active microlife in coco would help. No... I was using enough h2o2 to hear them fizz, but couldn't shift it.

Yeast gets in the air, and is a competitor. I have since used the warmth of my room to help the brew, but piped the airlock up and out to the loft above. Even when I can't see it in the pots, I notice a downturn that stops me mixing the two hobbies. Also the much more consistent white mold timing in late bloom.


With what I have seen, I struggle to see why anyone would be using yeast. Yet I have never read a bad word about it from others.
