Never seen many LED at the hydro store? Seems to be all HPS. Supply and demand no?
If LEDS yielded their weight in cost you would not see HPS dominating. Maybe part of it is the cheap non functional led panels vs the well built leds scaring people from dropping coin on a bad ass panel.
But i also know jack about economics so take that with a grain of salt. BUT -
I'm considering doing a side by side same strain same but separate tent, same everything. One with and amazon led (cant afford LEC) and one with a 400mh. Itll be cool I think.
I mean someone must have done that before but I will see with MY EYEBALLS
My two cents?
A well ventilated 600w. With quality clean bulbs. And the right climate. Your golden.
