what is cmh? ; google didnt work. ---- i've got some cfls, could i use those for veg and then do hps....If you mean "what is the best type of bulb to grow a plant from start to finish using 1?" then I would say CMH.
Otherwise, be more specific please.
do you have any knowledge as to what the yield difference would be?yea you can use cfl's and switch to a hps for budding you can use cfls the hole time you"ll get less yield but can still use them
that rep would be appreciated lol.
