advice please on orchidarium
 

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.

Photo please :)
And sizes: length, height, width, please :)

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.

ok L 50INCH W 14INCH H 20INCH i will post some photoes once it is completley set up as i am still avaiting some of the items in the post . should be up by friday. any general advice would be much appriciated

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?
