Yes when i said no root hormone i mean i use NONE at all for the cloner. They aren't needed. Some use emm some dont depends on you situation i guess. Some have good luck and other do not. I just would rather not use them because i have had better results without them.

Also you said that your cloner is homemade. Make sure your sprayers are hitting your clones. pretty much directly.

what size water pump are you using? and how big is your cloner? another thing what kind of sprayers are you using in your cloner?
