Pretty sure the blackstar doesnt outdo the blackdog led lights, especially the new models. But, to each his or her own.........LOL...I have a Blackstar panel from Gotham and a Kessil magenta (price is dropping). Kessils have the best penetration of any LED platform, but very low power consumption. One other consideration: their fan is very quiet...almost silent.
You can get a ProGrow panel from hydroponicshut.com and select the color output.
Good luck. Get good quality LEDs in whatever light you try: Cree, BridgeLux, etc...
You have any reason to think that besides guessing?Pretty sure the blackstar doesnt outdo the blackdog led lights, especially the new models. But, to each his or her own.........
Never listen to salesmen. Hydro stores make more money of HID, given all the accessories.my hydroponic store said fuck that shit..dont bother its a waste of money../shrugs
