A big shout out to GroZone!
I bought one of their simple USCO2 controllers but having trouble getting tanks of CO2 so decided to use an alcohol burner I made a few years ago and use the controller to see if I could monitor any increase in levels. Sent an email last night with a few questions but went ahead and used it. Was getting over 1500ppm with the RH/temp controller to my exhaust fan set for 85F instead of the 75F I usually have it at.
This morning their reply from the CEO nonetheless was waiting in my inbox and I had another question that he replied to within 15 min.
Great customer support for sure and what seems to be a really good product. Made in Canada and not some crappy Chinese POS.
They have lots of other products that I will be looking into should I need anything else.
Here's the burner with just one wick lit. I keep it in a 1gal stone crock just in case and have it in the middle of the room during use so there's nothing above it to catch fire should the methyl hydrate it burns somehow get loose and burst into flames. Planning to get some sort of propane burner going but this supplies all the CO2 I need for maybe a dollar a day. Making another one for use in the upstairs veg room now. Just a mason jar with a couple of copper tubes soldered to the lid and tiki lamp wicks in the tubes.
