I used a mars ll 1600 in a 4x4 and it didn't fully cover the whole canopy there was shaded area's but you could use a few Cfls or ufo's for recess lighting. I hope you received a Big discount on any Mars ll series lights, as they started discontinuing them over a year ago! mine blew before my first harvest 25 Diodes 7 weeks in bloom doing a 4 plant multi strain ScrOG. Don't get me wrong they grew Nice plants but there Diodes blow more on the series ll than any other mars lights! Just make sure you know about the warranty!!!

You can't put 8 plants under a Mars 1200 without recessed lighting unless your tent is bigger than the OP's tent. you growing Femmed seeds? 4 plants would be fine with a little extra lighting IMO. this is 4 plants ScrOG and I didn't have room to spare. Sent from my iPhone using Grasscity Forum
