Cloned a few WW loose about 3-4 per 100
Clean tools, clean room, clean hands
never alow the clone out of water more than a few seconds
Using perlite , vermiculite 50/50 pre damp for 1 day.
any rooting compound,
I use home dump antiwilt after there in the clone buckets.
Cover with a plastic tent or Clear plastic cups.
I think I can do it in my sleep.
With WW rememeber that air flow is important , as they are firm tight ass buds. Mold will start in a heart beat.
Firm tight buds pink or green I'm happy.
