Re: Oxalic acid use in Summer (August)
Jim, the white powder-like substance will turn into a vapor (oxalis gas) when they are heated by the vaporizer. So no need to mix the solid white powder with anything else. Just put the white powder into the vaporizer pan and connect away. Use the proper protection and I am sure you can hold a breath until you can get to open air just in case. Leave yourself an exit!
Don't mix foreign bees into a virgin hive. She might get balled 100% of the time! When will you ever learn, huh?
