you shuld get 2 600 watt leds, reason why two is you can lower the lights individually get the perfect height for the right par and spectrums on your babies, two will cost about the same as a higher watt led and you will get 200 more watts, the par 700 if you only wanted to get one would like that 5x5 up. vitra specktra or however its spelled. im using the par 600 on a side grow and that is bright like wow
i also run a mars hydro 800 watt and i thought that one was bright until i ran the par 600, it has 3 switches veg, blue spectrum, white that is bright like the sun and red. all three on is like why didnt i get these from the start
