DIY humidifier

Cross-check with the air over a saturated table salt solution, i.e. a pile of wet salt in a jar or tupperware container. This gives 75% rH, and is only mildly temperature-dependent.

Don't get salt on the sensor, as that will throp all subsequent readings off.

Confucius say "man with one watch always know right time; man with two watches never know right time".

I just have a wet and dry bulb version!

... which is inherently more accurate.

Though ISTR the wet bulb sock needs to be salt-free, distilled/demineralized water only.

I have one too, good old-fashioned mercury greenhouse thermometer.

Problem is the wick goes mouldy, black and slimy and I can't find a suitable wick substitute.

What do others use ?.

ISTR white cotton is fine, i.e. a clean braided rope with the core pulled out, or bandage material.

Or bleach the wick, and rinse it very thoroughly?

There are loads of humidifier designs on youtube, mostly intended to be swamp coolers. Search 'diy air cooler'.

For a cold environment, you'd need to add some heat.

Made me go and look. I thought they would be more expensive, but it looks as though they can be had for £15-£20. Presumably because they are a common item used by gardeners.

Any recommendations?

I bought a roll of wick from somewhere. Probably eBay.

lol.

People talk about humidifiers, in reality you can just use a handheld sprayer to dampen the carpet slightly - don't overdo it! Leaving an inch of water in the bath would also get somewhere.

I would go with a radiator humidifier, as already mentioned. Simple, foolproof and just works. Ceramic, can be hung behind the radiator if gap large enough.

trouble is I only want a piece about 4 centimetres long. if I bought a whole roll, I would then put it somewhere 'safe' for future use, and then never find it again (except when looking for something entirely different) :-)

I'll see if I can get a roll of cotton 'twine' and knit one. The twine is always useful for gardening and suchlike.

I'll let my sister-in-law know immediately.
