can i use a propane torch. the flame on the torch can be adjusted to very low, like a pilot flame. thats what ive been doing. my grow area is sealed air tight. i run the fans on high when im running the torch i usually do this 4 to 6 times a day for 15 min at a time.
when the temp goes up to 85+ i turn off the torch and then run the fans on low.
i havent had any problems doing this except knowing the levels of co2.
i suppose i could get a co2 meter. but thats a little pricy. or is it?
any feed back would be appreciated.
thanks sully
