How is an orchid greenhouse/hothouse arranged?

[AnonYMouse]

I've been to Inverness in July but my greenhouse experience is based on my dad's greenhouse growing up (about the same size as yours) in the SF bay area (temperate with 2 seasons).

My dad didn't grow any cool growers, he had Cattleyas, Phalaenopsis, Dendrobiums and Cymbidiums (actually outside). All warm growers so the greenhouse was to keep the plants temperate in Winter and hot in Summer and raise the humidity. It was rare to see the space heater in use, your location is likely to need heat. It was stifling in the Summer unless it was just misted (there was a simple overhead mist system).

Have you ever deplaned onto the tarmac in the tropics? The atmosphere is like that, going from an air conditioned airplane to hot, muggy air.

Sounds: water drips, water in hoses, water leaving the spray nozzle, crunch of gravel underfoot, creaks of wooden walking platforms.

Smells: moss, algae, flower blooms and sometimes, disinfectant.

Potted plants would be on some slotted surface, maybe arranged on multiple level shelves (high light plants above, cooler low light plants below). There might be plants in baskets or mounted on various materials hanging from joists/frame (watch your head!).

Hope that helps.
