How much longer should I wait until I start doing the 12/12 cycle? My plants are about 4'' tall and I have 2 florence fixures on them with 80 watts each. One on top while the other on the side. There growing fast. Could used some top-notch advice! plz!!!!!
Wait until they exhibit alternating nodes. This generally occurs at 4--6 weeks. What are you feeding them?
you can turn your plants over to 12/12 wen they reach 8-12" in height regardless of alt node developement,i would wait though untill they are agood 12"tall though,
It is best to wait till vegative maturity(alternating nodes) as rangerdanger said,you can place into flower a plant at any time but not waiting till vegative increases chance of hermaphroditism among other things.
