5x5 CMX22 Cob spacing

I am looking for the best spacing for my 5x5 grow tent. I will be running 12 Luminus CMX22 Cobs @ 73 watts.

I was thinking something like 14 x 18 inch spacing. Does this sound right? That would leave 9" side spacing one way and 12" the other.

I always try to design the fixture so that it fits the plant layout. How are you arranging the plants? How many plants do you want to grow? I'm asking this because trying to hoist a fixture with 12 arrays would be fun by yourself- splitting to smaller fixtures makes life a bit easier.

Thanks for the reply. I was actually going to split it into 2 fixtures with 2 drives each but didn't specify this to make my question more simple. I am running 6 5 gallon dwc buckets this grow but it may change in the future. I will make it so I can move the cobs on the frame if needed and I also have the ability to add 4 more cobs down the road dropping the wattage for more even coverage.

Right now I am just looking for the general answer of best spacing for even coverage.

Six 5 gal dwc buckets in a 5x5 tent?

Thats going to get crowded....lol
