advice please on orchidarium

[reefmale]

hiya guys , i was wondering if any of u could give me sum help on orchid tank. i have 500 litre tank which i have begun to adapt to orchids, i have 2 terra fans installed on the back glass faceing the front of the tank. i have 2 sonic humidifiers in a tetra water fall, 2 x 30 w light tubes ( plant grow and warm day light) an inch layer of forrest bark on the bottom of the tank which i intend to lace with staph moss this week, a thermomiter and hydrometer. most of my orchids are going to be mounted onto cork bark. i am also going to cover the sides and top of the tank with reflective sheeting they use for hydroponics. does this sound like a good set up any advice on anything else i should have or being doing, does it sound ok, any advice would be gratefully recieved.

Believe it or not, painting the the tank white is actually better than the silvery, reflective covers.

Shine a light on a mirror, and it reflects directly away at the same angle as the incident beam. Shine it on a white panel and it is dispersed quite evenly in all directions.

i may give that a try as the backing of the reflective sheets is white, thankyou ray

think i will still use the silver along the top though, , a combination of the 2 e.g white across back and sides and silver across the top

also im a bit in a conumdrum about the sonic fogger, it is best to keep it all day and turn it off at night or have on a timer so i comes on every other hour or similar, worried that as it is a near closed enviroment the water may build up inside the tank?
