cheap way to boost co2 - tell me what you think

A very easy way to create C02 for a very low cost is to mix baking soda and vinegar. The usual disadvantage is that the reaction is instant so the CO2 is drained out by your exhaust fans. A better way to sustain C02 output is to create a wick system. Take a red plastic cup that is 12 oz and pour vinegar into it. Create a wick system by poking a small hole at the bottom of a 16 oz cup and placing a few inches of yarn through it. Tie the yarn off inside the 16 oz cup to prevent it from falling through and cover the knot and bottom of 16 cup with baking soda. Place the 16 oz cup into the 12 oz cup. The bottom of the 16 oz cup should fit in the top of the 12 oz cup without hitting the bottom / vinegar. The yarn will slowly pull vinegar up and into the baking soda producing a sustained amount of CO2. Good luck and I hope this helps!

hey thanks for that! Useful second post!!!!!!

You're welcome. Question for anyone viewing this post --- since I've rigged the co2 wick my temperatures have risen. Should this be expected?

i dont know about that but with the added co2 your plant can endure slightly higher temps 80-90 maybe a little more.

Thanks. I'm almost up to 95

Watch it. 95 is the ceiling. Be careful. Also make sure you have adequate ventillation.

I mixed up warm, distilled sugar water and added brewer's yeast. Set the carbouy in my growroom and that was that.

Good luck.

i used the yeast method also..it works fine

95 is borderline using co2 that reaches 1500ppm, theres is no way in hell you are getting that from your home brew.
The method described above, is a "direct delivery" method.
At best, its a waste of time. If you insist on using it, and you allow your temps to reach even 90, your in for trouble.
Real co2 is cheap, why even bother with a home made brew?
Peace
