...I wasn't seeing my chams drink and when I spritzed the plants it would usually evaportate before they ever got to it...SO I decided I wanted to control it more and give it to them more directly. I have a 20cc syringe that I had used to give one of my cats' medicine (the opening is about the size of an "o" on this page - no needle attached). I fill it with water (spring water, for anyone who is worrying about it
and allow droplets to fall right near where the cham is sitting. Bart, my littlest guy, always seems to be the thirstiest so I go for him first. The girls don't drink right away but it stays in "puddles" on the foliage longer. Now, granted, this is rather labor intensive, but they are housed in my office (work from home) so it is easy to do. I also get less unwanted spillage onto substrate.
I doubt I would do it if I had lots of them and/or bigger species, but for these little leafs it works great!
