can anyone help me find the thread for making co2, i have some yeast and sugar but just wanted to clarify what i needed to do to make it all up,

Thanks

Peace

Use 5 or 6 cups of sugar in a 1 gallon container, make sure the container has a fitted lid. Add half a gallon of water to the sugar along with a couple of tablespoons of active yeast.Poke a small, pencil-like hole in the lid and place it on top of the container.

As often as possible shake the container to blend the mixture thoroughly. In one or two days the yeast will grow and co2 will be a by-product in the container. Now, every time you shake it a burst of co2 will be released into the grow room. Also it will continue to be released through the hole in the lid while you are away. You'll have to change the mixture once every 2-3 weeks.

thanks, that is just what i was after, cant wait for my babies to lap it up.

one other very important thing about that set up is when you release pressure after shaking dont let any fluid from iside jug hit your plant as it dos alot of damage

Thats a very good point, sorry I left that out... Peace

What I do is when shaking it up cover the hole with a wash clothe. Remove after shaking. This makes sure no mess gets anywhere.

yeah your grow room if small will smell like a brewery instead of pot big time!

gonna try this , what about a redirect bottle attachd with a hole in it for catching overfolw

If you attatch some garden hose from the top of the container and into your grow area, then place the end into a small bowl of water, large bubbles will appear and, (more impotantly), cease when the mixture becomes less effective. This will let you know when to change/agitate the mixture. (Ie: The bubbles will stop).

I would also suggest regular air exchange to ensure CO2 levels remain within acceptable levels, (Not above 1500 ppm for any prolonged period)

Also, the bowl of water could contain an ultrasonic mini humidifier in order to further dispell CO2 in a nebulised form. (For clones in prop chamber 70/80% RH (relative humidity).....For new plants in the main grow area 50-80% RH......For Flowering 35-50% RH..(Lower rates for rot prevention). As long as you replace hot, humid air for cooler air it will be ok...

Hope this helps someone!

Cheers

I ran this on my grow i just harvested all through the veg cycle. I'm not real convinced it makes enough co2 to really make a difference. I'm sure what it made helped some, but its really more of a pain in the ass than it is worth in my opinion. The up side is its cheap and wont cost you hardly anything at all to try it..


I just took a gallon milk jug and put a hole in the cap. Then ran some airline tubing(fish tank aerator line) up to the plants...

Mix 5-6 cups of sugar and a packet of yeast and your good,. I've seen people say everything from two cups of sugar to whole lb bag or however big the big packs of sugar come in.
