Low temp, high humidity

Well lads,

Im currently trying to get my grow spaces dialled in, i never bothered monitoring and controlling humidity befor, just left it do its own thing.

Ive 2 grow spaces both using leds,

1. 16"x20"x40ish high (used for autos)
2. 16"x20"x30ish high (used for photos)

The second grow space is the one im having the most problems.

Lights on temp/humidity are between 25c-29c and 55-65, Lights off temp/humidity is 15c-20c 70-90.

For a quick fix for now im going to place a tray of rice in there but for long term i was thinking of a small tube heater,

Anybody have experience with these types of heater? How hot to the touch do they get? How close to the plants can it be placed without doing damage?

A dehumidifier not only lowers humidity but they put a little heat out too.

I have no floor space for a dehumidifier, thats why i was looking into a tube heater to screw to the wall

You could build a shelf for the dehu.

These are small grow spaces,dehu the return air.A lung room so to speak.

Take meters out of grow and put in room grow is in, use an exhaust to pull room air into grow and voila perfect temps and rh just control your room
