I know that this is already a thread in itself but i wanted to share my idea of a simple c02 system. I used his method Cheap home-made C02
You can find it here.
What i did was take a five gallon bucket with an air tight lid and cut a hole in the lid, next i added my valve to the hole and sealed it. I measured out my tubing and cut it, adding little holes in the tube i was using around the plants.
next i closed the tubing(around the plants) with a three way split valve. I attached the tubing to the valve on the bucket lid and the went to make my mix. I just followed the directions in the thread (the Sugar, yeast, and toast) And put my lid on and will turn off my fan when the yeast starts to activate. (about two days, maybe less). I hope this will help anyone else, Thankyou to the person that wrote the first thread. hope you like it

they say using co2 for flowering is to help the yield you can also use it for veg. plants use co2 like we use oxygen, i think if you can monitor the amount of co2 you are feeding your plants you should be fine. Experimenting is how we have gotten this far, so keep testing your ideas.

nice design, does it really work?

Very cool indeed. Great Setup. Hope it turns out for the best!

Hey that is an innovative idea never stop experimenting...good job

I think it would work.. Like the co2boost bucket that recently came out

The tubing needs to be hung up higher. C02 is heavier than air and sinks. You might even put a small fan blowing upwards from the floor. C02 is used in the flowering stage to put on weight and it helps the plant in hot temps. The ideal temp for using C02 is between 85-87 F

thanks for the advice. I have a two fans blowing from the bottom (put in after I read your message) it works really well. I know it is used for flowering, but plants always use c02 so I leave it on when my lights are on and off when they are off.
