Would you be keeping both CMH grow lights in that space and just adding another light or two? Or are you removing those lights? Currently, since each of those lights covers a 3'x3' area, you need coverage for 1'x6.6'. Is that correct?

Im gonna keep the 2cmh and add 2 more leds for 6x6 square coverage for my 4x6.6 space.the room is 6.6x8 i only use half of it. l guess my question is this overkill or can i just add 1more in line for 3x9 with overlap will this be enough?

@jim curtin I'm not sure I'm understanding entirely. So basically you need coverage for 3'x6'. Is that correct? So two LED's with a 3'x3' flowering coverage area will work in that space. Do you have a LED light in mind? Here are my picks for 3'x3' space: https://www.mrgrowit.com/post/best-led-grow-lights-2020-3x3-coverage-area
