cfl og kush grow 3 weeks from clone, first grow.

i started with this clone on the 16th of june. i had some problems with it which i posted looking for help and i think everything is better now. this is my first grow and i want to know if things are looking good. size, color, all that good stuff. i have 125 watt clf on top, couple cfls on the sides. i took seven cuttings from the plant already which are in a aeroponic cloner. i used mx clone from hydroponix. i got a free sample and i was wondering if anyone elses uses it or am i wasting my time and electricity. from what i seen, you dont need a medium to clone right? just something to hold the clone in place. thanks.

use a cube of rockwool. plant looks great. nice and green.

thanks. i could get by without using a medium right? i mean if i dont have to buy it then why should i type of thing.
