20 Pound Bottle of Pressurized Carbon Dioxide
This shows the 20lb bottle that is feeding the smaller cold frame that is inside the larger structure. The reason for the smaller cold frame is that it is easier to regulate the temperature and CO2 in a small area.
The controller (Atlas 9) has a “fuzzy logic” feature and with the small relatively sealed cold frame and a small plant (not consuming much CO2) and some “free” CO2 from the compost, this 20lb bottle lasted 17 days! However, as the season progresses the same 20lb bottles will last much less time.
“Fuzzy logic” is a computed release of CO2 to help reduce large swings in CO2 levels to help not over add and conserve the total amount of CO2 used. It adds to the cost of the controller, but the long term savings and reduced hassle of bottle moving is well worth it.
