3-5 days 12 days Wat's the secret, I took my last cuttings on 2-11-08 and they didn't have roots out of the 1" rockwool cube until 2-28-08 that's 17days for the first roots to appear on 2 out of 9 of the clones. I took another 4 days for four more to grow roots out of the cube that's 21 days for 6 out of 9 clones. I wounder if its the cloning method or plant genetics that determines how long it takes a clone to develope roots.
