Ok, after much playing about I have discovered a few things! One is that despite the super rain being a sealed sytem that is pressurised gravity still works and if you place the water tank above the spray jets then syphoning will take place and the water tank will empty into the enclosure over night
After much tinkering I have managed to get the ratio right, humidity level is set at 90% and switches at a 5% difference. so when the humidity level hits 85%, the pump kicks in and it rains for approximately 20 seconds which takes us back to 100% which slowly evaporates down. In an 9 hour period it only rains twice

But on much drier days I guess it will rain more often.
It is also important to position the sensor well out of the way of the spray jets but somewhere to get a good humidity reading, I have found the best position to be directly behind a spray jet and make sure no other jets are aiming at it.
Once the humidity plumbing was sorted, I have had time to fill in the substrate of LECA (lightweight expanded clay aggregate) which has been very well rinsed, the spray jets have been disguised using Exo Terra bolivian croton plants. These plants were chosen on the very loose premise of that they are supposed to look like something from the bolivian jungle (correct me if I am wrong?) which is in south america which is also where the dart frogs come from!
A big Xaxim trunk has been added (whats Xaxim? I hear you say) Xaxim is basically dead bits of an endangered tree fern

So probably will be banned from import soon and as such is quite expensive

But the dead fern contains spores of the fern and mosses and under the right conditions will sprout interesting new life (if you are lucky):D
Plenty of live spider plants, orchids and bromeliads have been added along with two lucky reptile half coconut caves covering shallow water dishes. and some live sphagnum moss to finish it off.
Pictures will be here soon
