Cloning in rockwool in aero setup

So I have my aero setup going and so far so good. I'd like to clone the grapefruit I have in soil. I started a clone just in some rockwool in a prop tray. Ph 5.5-6.0. Now I read to use 1/4 nutes since ofcoarse the rockwool has nothing in it to help of my babies. I'm just not happy with the results. My question is how much better would it work I have the rockwool in a smaller starting aero system that I will have to build? Any advice on nutes to use or stregths or if my clone in its little tray will some water in the bottom be good enough?

did you use hormones? like root gel or the powder?

yeah I used rootex powder

anyone else?

I root my clones in my home made DWC unit. Easy to make ... and cheap too.

I use 1" Rockwool and 2" net pots for this. When they are rooted, I transfer them to 3" net pots and into my aero unit for the completion of vegging and flowering.

For the cuttings/clones, I use rooting powder, RO water and NO nutes at all. Success rate is just about 100%.
