Building an orchidarium - need advice

[s1214215]

Hi

I am getting an orchidarium made here in Bangkok. I need advice on how thick the acrylic sheeting should be. The acrylic workshop here seems to think that 8mm or 1/3 inch thick acrylic will be ok. I did see in a forum that between 6mm (1/4 inch) to 12mm (1/2 inch) would be ok. I cant find the thread again though. What thickness do members here think I should use? Will 1/3 inch be ok?

Case measurement is 51 inch (1300mm) long x 42 inch (1070mm) tall x 28 inch (710mm) front to back.

My case will be modelled on this case in this thread

I will get a stand made similar to the stand in this thread, only mine will have 4 posts to support the canopy so that the acrylic case will have to hold no weight. The lighting will be 2 x 4 54 watt tube T5s with individual reflectors.

I will keep a mixed collection, aiming for low light growers at the bottom with more light needy plants at the top.

I'd appreciate some feed back on this plan.
