I personally dont run anything other than lights and ventilation. My room stays 76-82 depending on temp outside. I do flood tables and do find my air a little moist however it's not an issue in my space. My area is a high humidity area so I just try to run more fans than I need for my space.
I have roughly 8'x5' with 600w worth of cob led not producing much heat. With a 12" circulation stand fan and a small 4" fan for an led board I built. 2 4" online fans with filters venting into the attic through a 4 to 8" vent.
With all that said if your environment is good without adding a dehumidifier/humidifier then spend that money on something else. 1000w of hps is a lot of light, that much power is capable of producing a lot of bud on some pretty big plants. Invest in your grow area first to optimize that and then genetics. That's my advice. If those 2 are covered then sure splurge on some cmh bulbs, I'm not familiar with them but many on the site are.
Let us know what you decide to buy, good luck grow bro. Sorry for the book.
