Re: TBH and oxalic acid
I saw a thread where they set a small pan of acid on a hooka charcoal. I was able to use this method in my top bar by moving the follower board out a couple of bars and setting the charcoal and acid on the floor of the hive. I also used this method on two nucs and a ten frame hive. it has worked well three times so far and not so well twice. the coal went out on two of them without vaporizing the acid. will retreat those today.
