[dissident]

For all you pros out there what would you go with for a 240gal tank. 72Lx24Dx31H
Priceing everyhting out MH and PC ends up being about a $30 difference to get 5w/gal. Due to the depth of the water I am leaning more towards the MH solution.

MH
3x400W
(1) 10k
(2) 6500k

PC
16x65W
(4) 10k
(12) 6500k

Thanks in advance.

They won't all be running at the same time as in a dusk-dawn type mode. I really want to start keeping some high light demanding plants, will be using an in-line CO2 reactor.
