HPS is not in a class by it self, an HPS is an HID, HID = High Intensity Discharge lamp, an HPS (High Pressure Sodium) and MH (Metal Halide) lamp are just HID's which are made for higher wattage than most lights of course, but that doesnt mean you cant use a few CFL's (Compact Fluorescent light), you can use a few CFL's that might output the same ammount of light as a 125 w MH or what ever.
orangeman Reviewed by orangeman on . Is there such thing as a CFL seed? hey 2 all strain experts out there, i havnt found a thread on this site or any dot com site that has plants listed that will do well or made for CFL's. most plants grown N harvested 4 seeds were done under HPS and HID lights yes i kno this but is there any particular strain that will do just as or close to the same yield as it would under a HID or HPS? any advice or 2 cents would be helpful Rating: 5
