Better yields with home made co2...

Ok so we have all read the threads about making co2 for you grow room with little to no money spent. Get a bottle add water, yeast, and sugar. My question is, if I attached a thin hose to the top of the bottle and ran the hose to the inside of my hempy bucket, would this increase yields? Or would it be better to just set the hose on the top of my plants? What do you think?

Comment or suggestion?

roots like oxygen, so this would be bad.

pipe it up and around the leaves towards the top of the canopy. It will trickle down and feed some of the lower leaves too.

I'll stick my foot out since I'm new and inexperienced.
I wouldn't know about yields, but i can't yet see the benefit in a small grow...plenty of air should be enough
for a cash crop, you might as well just invest in tried and true tech...cheaper in the long run, sugar gets expensive.

I'm just gonna brew my wine in the same room and have a fan on the ground to kick up the gas that vents from it.

See attached for how i do it for my aquarium plants if it helps any...the gas separator imo is essential, unless you like yeast water spraying all over everything

try to search for desert rats co2 mythbusting thread. he broke down the math and you are very right, the sugar adds up very fast. the yeast adds up in cost as well, though you should be able to breed and keep recycling it, so in theory you could just buy that part once.

after thinking for a bit...a friend once told me a simple lit candle produces enough CO2 for a few plants.
makes sense to me.

i would never suggest leaving such a system unattended of course, but it's food for thought

EDIT:

Like those candles dedicated to various deities/saints you can buy at the supermarket.
Aren't suppose to put those out anyways.

Yea I'm probably going to just put a bottle at the top of the grow room, it probably wont make much of a difference but I guess we'll see.

If its not brewers yeast it will die within a day from the alcohol. So really youre just wasting money

Damn that sucks, are your sure because I read differently on other threads? They said you could use any yeast and it would be straight, im no expert though.

fifty dollars and you can buy a homemade beer kit,get a ale pail and have good beer in 40 days youll have three cases good beer and for a couple of weeks it puts out so much it blows continues out a 3/8 in hose.so do one batch every two weeks and you will have co2 and a hangover..happy time

I like the sound of that

This sounds pretty promising, but if you have a strong ventilation system, even just a single fan in a small area, would the CO2 make a difference or would the constant air flow just eliminate it before it has a chance to be used? And +rep both you guys for simple and easy ideas. Might try this next time if it is beneficial.

If you're going to be spending the money for sugar, you might as well spring for the more expensive "champagne" yeast.
It has a much higher tolerance for alcohol (which is what ultimately kills the yeast) and so will last much longer.
The slightly higher price for the yeast is quickly offset by the savings in sugar and the hassle-factor of frequent changes.

crap, homemade co2 systems are crap, not cost effective or even effective. you need a CO2 monitor to know how much you ppm is or else you're doing nothing and if you do the maths on the sugar yeast thing and see how much sugar you need, you will be surprised
