Infinitely.
Because if you put it under a HPS with crappy root development it's going to croak.
If it has just okay roots it will be limited by the nutrients it can uptake.
stinkyattic Reviewed by stinkyattic on . when to flower a clone ok.. u cut the clone.. dip it in the solution.. stick it in the dirt.. light it for 1 week 24 hrs.. 1 week for 18/6.. and another 18/6 for good luck.. when could u start flowering for a good yield?? do u actually have to wait for it to get as big as your mother plant was? the way i'm seein it, when u cut it and it has its preflowers, it already has its stage set, so its kind of like repair instead of regrowth.. if that makes sense..
