Humidity Issues

I am currently having some humidity issues in my flower room. I can not get the humidity below 50 percent.

I run 12 1000w HPS in 8" Blockbuster Hoods. Currently 8 are ducted and spitting the heat into the room. The other 4 are being ducted out of the room. I have 2 100 pint Ideal-Air Dehumidifers. I have a 6 ton mini split system. 3 units 24000, 18000, 12000 BTUs in the Room, and another 12000 BTUs outside of the room. I have the units all set to 70. I also run a Ares 8 NG Burner. I calculated that it needs to run for around 9.47 mins to get to the 1250ppm of CO2. I have one of the Ideal Air Dehumidifiers mounted on the wall and one mounted on the floor. If anyone can provide some insight I would greatly appreciate it. My room is 25x14x8

Dang, that's a bad ass setup for a newbie. If your using co2 you can have higher Temps. I'm surprised with all the lights the humidity isn't lower, it would seem the heat from the lights would dry the air out. What exactly is your humidity?

Not for the NEWBIE section my Freind because if ur a noob ur in big trouble...

You're way short on dehu.

One phoenix 200 max will handle that assuming your not venting in Louisiana like humidity...

Uve jumped in at the deep end my friend. Go purchase some arm bands lol
