If you are asking for my opinion about the SS 400's I have nothing but praise for them I post on another site and many people on that site have praised the lights and are looking to but one as far as the performance I really couldn't be happier. Unless the price was lower but at $599 I figure you can't go wrong as a matter of fact I bought a second light because I believe the light is the best one out there right now. I think most of the LEDs for growing will grow plants but not all LEDs will grow the best plants. Just my 2 cents. When harvest comes the proof will be in the weight and quality of the buds. Hope this helps anyone thinking about buying LEDs.
The posted pics' are of day 35 of flower I am using DLR and the plants are maturing early as you can see I have about 50% of the pistals turning orange I think these plants will finish up two weeks early from a test of the trim leaves I would say the White Widows are gonna be strong
