Hey brah, right meow i'm cloning with an ez cloner 60 site and just been using the roottech cloning gel on the stems, put them in there, wait 10-15 days, and cash money comes out. no solutions needed, but if you wanna get a little more aggro on the rooting, you can use the Clonex solution, comes in a black bottle, works like gold. Not really necessary, but it'll keep the green in the plants and help them stay healthy and reduce stress.

hope this helps!
