The wet towels in front of the fan sound like a good idea Elaine. If I recall mine did pretty well last year through the rest of the hot summer. I got them in June and repotted them. Of course between June of last year and now I've lost 8 of the 23 but I don't consider that too bad of a loss rate. I'll try the feeding with the potassium nitrate and Epson Salts next time I feed. What do you use about 1/2tsp of each per gal?
