i took 2 clones for the begining
and i made a DWC cloner with a humidity dome
really ghetto and cheap one but it works and looks wonderfull
u can find details in MY SETUP thread
i didnt find a heating mat

CONDITIONS:
55W CFL bulb
lights are on 24 hours a day
water temp - 24C
using a ph 6 water
and a 300 ppm (0,5 EC) GHE roots boost solution
humidity - 75%
the dome keeps the clones well sprayd all the time
