I already heat with propane so I have the monoxide detectors covered... is there an "affordable" burner anyone recommends?
Depending on how you cool your grow space you need to consider how many BTU a burner will add to your room. A 4 burner will add 10,000BTU/hr to your room. It won't be running 100% of the time though so you can reduce that 10,000 BTU by a factor of the run time. But it's definitely a consideration. I like bottles because they add no heat and can't produce carbon monoxide. But both options work great. I think bottles are better for rooms like 6-12 lights. Also if your room is venting all the time Burners are much better as you will run a bottle empty in no time like that.
