worried about humidity

So I just started flowering my 5 plants and I'm worried about humidity. During the day it stays around 65% and overnight peaks around 70ish.
I have 3 hanging "damp rid" things to collect moisture, as well as 2 that are on the floor.

My setup is in a closet: 2ftx8ftx8ft. it has double doors, but i have a mirror on the inside of one so I keep that one closed and the other one open.
temp is usually between 70-80 degrees.
lights: 1 90w ufo led, and about 200w of cfls.
I also have 3 fans that are on 24/7

Outside, the humidity get to the high 80's at night.
also, I have a turtle in my room with a 100 gallon tank which probably affects humidity as well.

If possible, I want to avoid getting a dehumidifier due to initial cost plus energy costs.
Also I don't think I can make any vents or holes in the walls.

any ideas?
thanks

There are two ways to lower your humidity. One is with an air conditioner (lowers my humidity to 50%, also lowers temps) and the other is with a de-humidifier. The de-humidifier will raise your temps by about 5f.

Also... get a lizard

get a new place to grow

Put dishwasher salt in a large bowl at the bottom of your tent/grow room. That will collect alot of the moisture. You will however need to replace it from time to time, it really depends on how much moisture there is.

I've read that having stuff to pick up moisture also takes moisture out of the leaves of the plants so they havta be kinda far away from them, you think it would be alright at the bottom, next to the pots?

i'm trying to do it without having to add more energy costs, but that may be my only option i suppose...

also i'm thinkin about getting a chameleon, they might be down for the humid climate
