Yes. I have tried lots and lots. I just use the simple Shultz powder. I found it was not about the rooting hormone to get high level of survivors. It's the full routine. From heat, moisture, healthy cuts, technique and lastly the rooting compound.
I had a lot of problems cloning until around 6months ago when I made a few changes to NorCalHals routine http://www.marijuanapassion.com/forum/showthread.php?t=33009 and now I get 100% rooted clones every time.
I never use a heat pad or heated propagator, they get too hot imo.
I give them 20/4 lighting, before this I used 24/0 with decent success but since the switch I now get rooted clones in 10 days every time, even from sickly plants.
My kit consists of:
Cheap propagator, £3.50
Iso alcohol £1.49
Rockwool £7.70 for 77 1" cubes
Scissors Plate & glass already had lying around
Patience is also required but thats not a buyable product!
