Root Stimulator?

what works good with cannabis ive only done garden fruits and veggies so far and this is my first hydro grow but the only question i have is what is a good root stimulator/treatment process to use?

I've always used a cloning gel that has the most IBA in it, that's indole-3 Butyric Acid. I've found that Clonex and Root Tech work well for me.
