Dehumidifier recommendations? RH throught the roof

Hello ppl

Can anyone suggest a dehumidifier for a loft room 1500mm in height 1900mm long 1300mm wide.

This is a small room and have 4 plants and they are in day 13F and I can get humidity down to a safe level.

They have just been defoliated a bit but not too much ans I have the exhaust fan running with good air circulation.

It's winter here and struggling to get RH down.

Thanks

A dehumidifier in that small of a space will get hot. You might want to increase your air exchange and, if needed, dehumidify the room from which you draw your intake air and adjust your extraction fan to draw in cooler, drier air to offset the humidity generated by transpiration.
