My Orchid Terrarium Progress

[Turtle81]

Hi, I decided to start this as a place to show the construction process of my orchid terratium, you can see my initial designs in this post: Advice on layout of foam terrarium insert ?

This is the unit before i started:

The next step was to make up a tempory mockup that was just held together with tape to see what it looks like in the tank:

The foam you can see was collected from the bin outside my local electrical goods company (from around fridges/tv's etc) for free with their permission.
So i spent the afternoon cutting out the shapes and decided to not counter sink the pots yet instead to just make the top platforms the right hight in relation to each other but make the clearance at the bottom lower so that the tops of the pots will be sitting at the right hight.

Now its time to see if i can get it in the uint in one peice !! as you can see bellow the plants will stay the same hight once finished, the next step will be to cut the holes to counter sink the pots below the surface and to pack the bottom level up to the correct hight.

I decided that i like the step hight's but am a little concerned about the over all hight, i would prefer to have the plants a bit lower only i just drop the light levels down to far as it is i am only getting about 8000 lux on my light meter when reading at the level of my lower plants (12 inch). I am running 3x 6500k HO 24W T5 bulbs and one 10000K HO 24W T5 bulb, i thought that that was going to be enough but think i might need to get some LED lights to help suppliment the lights without driving up the power bill ... peoples thoughts? from what i read i need 2000fc (21000 lux!!) although i have heard some people have grown them under 3x 24W HO at 12 inches?

Next update in a week or so
