Humidity

So I have problem with humidity at night. In day time(lights on) it's okey 50-55% but at night humidity rises till 80%
I need to dehumid only about 1.5m3 space so - do this small dehumidifier will work?

do they work at all? someone have tried them?
Or mby try kittie toilet things? I doubt i can find "crystal" Kitty Litter so do something like this

also will work?
I hear rocksalt also works - I can try to found old salt lamp

or this is different salt and wont work?
Or mby someone can suggest something different what works except to buy big pricely dehumidifiers?
Tnx.

Whats ur air circulation like? Good air circulation will keep rh down

So will a bit of heat during lights off.

Very true! Maybe get a fan heater with temp control, get the temp up to say 18 or 19 and u should be looking at a rh of say 40-50% which is sound!

I use an oil filled heater, set it on med/low. My Rh came down from 80's to 50/68%.

Ive got a fan heater, brilliant but its a nightmare on leccy!!

I know bro! That's why I decided to use the oil heater.

Hmm idk how its works for you but my temps at night is 19-23C in same time humid goes till 83%. So heater is not my option There is things like kittie litter witch i can drop in closet or hung on the wall to lower my humid without extra heat or sound?
And one more thing i said 1.5m3 not m2! ~78x78cm - have no place for heaters!

Struggled with this for last 2 weeks. Finally need full size 45 pint LG dehumidifier. Tried Damprid, a little dehumid like the one in your post...rice....everything. Nothing worked except the dehumidifier. Get ready for some extra heat at night though...about 8-10 degrees.
