I turned off the 5w individual leds and turned on the COB 3500K consuming 50 watts for 9 small plants in 1 liter pots since day 12. I started the week with 400 ppms and finished with 500 ppms. Very beuatifull leaves.
@bobo420,Thanks bro, the Light seems to be very good and efficient, I'm going to use 2 of this lights and 2 Óptic One lights (One CXB3590 chip each one) for flowering a 4x4 tent.
