the system I'm talking about is at CO2 Boost - Supplier of CO2 producing mixture for the purpose of CO2 enrichment and air fertilzation - it sounds like your looking for something a bit beefier - I just don't want heat or tanks in my small space. Thios bucket is mushroom spors, etc - has no smell and the plants are doing fine with it - although it is way to early in use to see any effect.
