Warning: Cloning is almost more addictive than growing. I currently have 6 clones in veg and 21 clones in my propegator. And about half my flowering room is clones. I love cloning...
I concur. My first cloning efforts (which were 100% successful, by the way) were done using the ever popular Clonex, but frankly, that stuff is a little expensive, very icky, difficult to get out of the package and wastes a lot. Then I tried a liquid that you were supposed to soak the newly cut stem in for 60 seconds then transplant. 100% fail. I switched over to powder and I will NEVER go back. I have not only had 100% success rate with powder, but there is very little waste, the stuff is wicked cheap, and I just dip the stem and go. I highly recommend cloning powder.
