New Grow Cabinet Opinions Needed

Ok its almost done 5'6"high 6' long 2'8"deep with a cloning room that is 2' wide and 2'6"high...In the cloning chamber I will have 2-75 watt floros and the main compartment will have a 600 Watt digital Ballast with both HSP and MH lamps, air cooled 6 inch hood fan with carbon filter...Fan will be mounted above the cloning chamber on the bench part of the unit...Please give my your opinions before I finish this, will be complete within 4 days

Do you have an intake and exhaust for the air-cooled hood?

Turn everything on for a few days and monitor the temperature before adding any plants. I have a 400w HPS with a homemade cool tube in a smaller cabinet and it took me a lot of trial and error to get it under 80F.
