I just got done making that same tea,take an old pantyhose,or old sock.i start with a gallon of water,put the teabag in for 24 hrs.then ready for use.autos are light feeders.i don't go over 200ppm per feeding,u may have to add water to bring down the ppm for sitting overnite.that's what I do.and I have been doing it like this for 5 years.Put 4 table spoons of the flower girl in the tea bag,add a air stone
