yup..btf is correct :thumbsup:

whichever method you choose for co2 enrichment its not cost effective to notice a difference...so do some reseaerch and when it is feasible then get the right system. bottle, electronic ignitor generator(propane or NG), i just put one in but it is the burner with a pilot light...if you have a small space a single burner is all you need and run on a timer until you can afford the monitor controller....in other words one step at a time and you'll be happier learning when you can do each step correctlly and not spend more money and effort on shortcuts.:hippy:
