promoting root growth in clay pellets?

Anyone know of any good ways to help a clone establish roots in clay pellets? i used a light dose of clonex poured from top already and the plant is in a DWC system, i just want to see roots coming out of net pot asap as the clone has seen better days and im afraid it will perish if it dosent get established quickly.

Pot clone such that existing roots are on bottom of net pot. Bubbles from airstones popping at the surface of your nutes will mist the bottom of the netpot. Roots will drop in short order unless you have pythium.

Best way I have found is spraying them. As those clay pebbles hold a lot of moisture.

As above poster said the air stone keeps bottom half the net pot moist.

Now amount times they need spraying depends on light, room temp an humidity.

i repotted it so the roots were on bottom of net pot. will be getting some dutch master zone soon as well so i dont have to worrry avout root disease
