The one unit is running both my cham enclosures and it's not even up to 50% power.
The mist was more like rain so I swapped nozzles out for £10 for 4 and it's brilliant!
I use a seconds timer with it and it's as good as anything else out else out there. It's also self priming. Only downside is it's a bit noisy but nothing silly.
My mistking (the starter one not the huge one I was looking at by mistake lol) finally came and I am head over heels! Its so nice not to have to constantly worry about hydration and keeping the humidity up. Thank you everyone!
