,A diy c02? How?
,
Hi Cookie Monster,
There is loads of info here about Co2 generators, hit the search button.
The easiest way is to use vinegar & baking soda. Set up a bucket with some BS in it and a way of dripping the vinegar slowly into the mix - this makes Co2. A simple fan attached to the bucket will flush it out & over your plants. (When the lights are ON only) There are Co2 buckets you can buy too that use a funghi to create the Co2. There are also very technical systems that cost $$$$.
Hope it helps fella - take care & happy growing
Sweet i'm going to look into that. does that cause the room to run hotter as with other c02 units?
