Question building grow room



I am building a grow room in my basement. I will have two tents 1 @ 2x4 with 2/ea 300 watt leds scrubber inline fan and circulating fans, 1 @ 2x3 with 450 watt led with scrubber inline fan & circulating fan.I will be drawing air from air conditioned basement and exhausting into same basement. I am thinking I will need an dehumidifier to offset humidity.Do not really want to exhaust outside and run my heating and cooling bill thru the roof.
