wheres your dome???.... It will help keep the humity level high and warmth to the roots...placing as heating pad under the starter tray makes the clones root twice as fast

I use dip-n-grow rooting hormone and a seedling starter with a dome for my starts and 2 shop lights (160 watts on 20/4 off) and I have a 99% survival rate

Dip-n- grow is a alochol based hormone in a concentrated form... use 1 cap full DG in a shoot glass of water
