Ive gotten mixed reviews on the Mars II lights. So I just purchased a Mars II 700 watt (140×5) for my 3x3x8 tent. I am expecting a delivery date of 11/20. I am going to document this and see for myself. Ive read all the specs which are too technical without referencing a ton of stuff. I know nothing about light frequency etc. SO it will not have technical info. I will copy and paste the stats regarding technical stuff and wont be addressing it. I will just be testing it in regards to does it work well enough to justify its cost. I got this one for $ 240.00.
