How much area can (2) 400w (1 HPS; 1 MH) cover?

I am mounting these so they can be switched on a daily basis. Please help with coverage area of these two lights. Would like to space them for most efficient light- space usage. Sun Systems reflectors. Thanks

I am planning on using both while I flower and vegging in a different room under flouros. I was thinking that 3-4 plants under each 400w would be sufficient. Any ideas?

Depends how you're growing.

If you have a veg space and are taking clones, you could put 9 or more plants under each light. Just flower them when they're about a foot tall, Sea Of Green style. Do this for many small to medium plants.

OR, you could put 2 - 4, big, bushy plants under each light and harvest few, larger plants.

Personally, I'd start from seed, choose a few good, healthy, nice smelling females, veg them for a couple of months, take as many clones as possible, keep the best 18 and flower 9 under each light.
