they have to root...during root formation, the plant remains dormant, basically, then after roots take hold and uptake nutrition form medium...they start growing again. NO nutes until they have 4-5 true sets of leaves, which in turn means they have a strong enough root system to sustain the plant...start with 1/4-1/2 nute strength for a week to acclimate plants to nutrient regimen. goodluck

And, I agree with Z...clones root much better under fluorescent light. I found this out by trial and error...leaving my aero cloner in the veg room under HID contributed to my clone success rate dropping drastically.
I know for sure, because as soon as I put cloning op inroom wioth fluoros...all the roots and success % came back up^
latewood Reviewed by latewood on . Clones stuck in neutral ... I had this posted in "Advanced Growing', and really should have put it here, I guess ... sorry about the double-thread ... anyway, my first clones took very easily to their soil ... I used the standard cloning methods ... now, I have little clones, that look perfectly healthy, but after 3 weeks, or more, are the same size as when they were taken, maybe even smaller ... at first, I assumed the plants were just busy building a root system, but after this long, I am a bit stymied ... is this Rating: 5
