Dementions

what size cubes are you using if they are the traditional i foot size 5.6ft by 3.6 ft or 67.2 inches by 43.2 inches about

and that would be the cloraplast demitions right?

Well, You would need two sheets of 4x8 no doubt of that....
Then, you should just lay out the cubes on it and do the measuring. No biggie, it's quite simple. Make sure the two sheets of coro are right next to each other, tape it down securley, and you should be ok.

52.5" by 83"--lay out the cubes and measure just to be safe, then add 12" to each measurement (6" per side).

ok thanks.
