the bowls of water are for raising the humidity, i do clean them 2 times a day. the plant is a hibiscus and it is 30" high by 5" wide. i live in moses lake WA. sorry but i can not get any pictures. i have a habba mist that is spraying 1 minute every three hours. i also spray by hand once a day. my humidity after each spraying session is 70-80%. i am measuring humidity with a humidity gage. plastic with an arrow pointing to the amount of humidity.
Few problems.
1. Those plastic dial humidity guages are notoriously innacurate. You may went to invest in a probe thermometer/humidifier to get accurate measurements. You can find them for like 10 bucks at home depot or lowes in the weather monitoring section by gardening.
2. If you live by a lake, you should have good ambient humidity to begin with.
3. Ditch the bowls of water, people have had chameleons drown in some rediculously small pools of water. You are putting your chameleon at risk, and the bowls of water won't provide as much humidity as you think.
4. Chameleons need to be stimulated to start drinking. With a 1 minute mist, they have 30 seconds to get stimulated, then 30 seconds to drink. You should be giving them a few minutes to get stimulated, then a few more to drink. If anything mist your chameleon as long as it is drinking.
You need to adjust your misting schedule for the hydration of your chameleon and to increase humidity.
You seem newer to the hobby, reading this will help you research so you can avoid future problems. It is a short comprehensive read, so I suggest killing about 10 minutes reading it, for the sake of your chameleon. I know it helped me learn alot before jumping in, I reference it alot as well.
