First time growing hydro... Tips? I think I got my set up right?

I am growing hydro for the first time and want to get some feedback on my system before I start the ladies. My grow room is a 5x5x8 tent that is completely sealed. I have a 1000watt hps in a 8inch air-cooled hood attached to a 8inch inline 755 cfm fan to cool it. Using the CAP Ebb and Gro 12pot 2gallon system using hydroton as a medium with a 55gallon reservoir outside the tent. Got a 20lb co2 tank attached to a CAP Fuzzy logic co2 controller set for 1500ppm. Have a 10,000 btu a/c with dual hoses going outside the tent. Got an 8inch 755cfm inline fan attached to a carbon filter inside the tent that runs twice a day for one minute to "scrub" the air inside the grow room. Have not bought a humidifier or dehumidifier because I dont know which I am going to need yet, does anyone possibly have an idea which one I will need with the 1000watt air cooled lamp and 10,000 btu dual hose a/c running? I know everyone hates this question but since I have been pretty precise in explaining my set up I figure someone will have a thought on it. At best what can I possibly yield growing 12 hindu kush plants in 2gallon hydroton ebb and gro system using advance nutrients under a 1000watt hps light with a primary pot space of 4x4 and a grow space of 5x5 in nearly optimum conditions with co2 at 1500ppm? I want to vegetate 18/6 for 4 weeks and flower for roughly 8weeks on 12/12 .

Thanks in advance for your input or advice.

hindu kush can really pack on some weight, You should get about a pound out of that.
I think the a/c will keep the rh down well enough. Maybe add some when there young.
