Wanting to get supplemental lighting

currently with the 1200 watt phlizon draws actucal wattage at 300 that should cover 3x3 effectively so wanting to cover 4x4 going with 4 green crack autos last ones grew really tall and at least three of them look like prime candidates for some LST and a trellis net been looking at the meizhi and mars hydro maybe Viparspectra (but hard in the blue want some supplemtal lighting for flower so up for any opinion and why....as well does any one know the gram per watt for 1200w phlizon

I would look at optic 1 or optic 2 a bit pricey but good gear, or go to the LED page here and ask about other plug n play COB lighting
Cheers
