farmerguy sorry to hear about your troubles!!

I have been using a bubble cloner for about a year now with excellent results.

The only time I had any problem was when my temp. got too high.
I had the cloner above a little Veg. area and the 4 100w. CFLs were heating the clone area.

I use no Hormones at all! I take cuttings, place in cloner, that is filled with just tap water. Presto about a week I got roots.

I start with cuttings about 1/4 inch into the water and at end of week just the bubbles are feeding them.

Good Luck!!!
