I'm new here and have not grown in fifteen years.
After a solid month of research Ive narrowed my choices down to three lights based on PAR output data and my budget ceiling of 850.00.
California Lightworks Solar System 550, Optic LED's Optic Six or Truth LED's M9.
This is where I'll be purchasing the light;
I'm placing my trust in this store from numerous positive feedback from other growers that have purchased from them.
Good luck and enjoy your grow!
