Hi, my friends I´m trying a new Led Grow Light the Parfactworks 160W (Consuming 86 watts), it has a 100w 3500K COB (consuming 50w) and 12 5w individual leds (consuming 36 watts). It has one switch for each channel, for the first week I´m using only the 5w cobs for 9 little plants cosuming only 36 watts.
