Where should I put the gauge an the room is quite cool even when it's hot outside . Could I get rid of a fan to raise the humidity
nice work , like the whole room conversion, i put my gauge 3/4 the way up my tent so its easy to read

so have you got the humidifer

my little 6l humidifer from ebay gets me from 30-40% upto 55-60% but thats in a tent, you might need a bigger one for that room

big W got some good ones i saw for 300ish

two ebay cheepies might be cool so you can hide them under the canopy when it grows bigger

Can anyone tell me if this is good humidity temp for plants
Not good at all. At that temp and what looks like early veg you want relative humidity at 70-72%, assuming a leaf surface temperature of -1 under ambient, that will give you a VPD of 0.9 at 72% RH, which is ok for early veg...lights on. You’d want to bring RH down from that at lights off with the temp drop.

Problem with most humidifiers online and store bought is they only have a small water reservoir which is not so good for what we do, what they do have which is good is a humidistat.
You’re better off making your own, have a look here to start to get an idea. You’ll also want to be using RO water in them, and get a controller with a humidistat. If you want some guidance on which one to use for your room size let me know.

Start researching vapour pressure deficit. That will get you on the right track.
