I'm sorry to revive such an old thread, but I was directed to it by JessB, and ST's observations are so invaluable!
I am dreaming of owning a Diamond, and rather than putting me off, this thread has made me more determined to get one.
I have spent the morning taking notes, hoping to design the perfect outdoor enclosure one day (will spend a year or so researching). I like the idea or a vine/climber covering over the top and 'hot afternoon' side of the avairy, to allow for insulation but a little natural dappled sunlight.
Would I be correct in saying:
If I provide an outdoor enclosure, with natural sunlight until noon, a warm spot (maybe heat pad) during the mornings in winter, and cool nights (in summer, perhaps assisted by a fan or even old-fashioned 'water-drip meat safe/fridge' type system), plus cool refuges during the day in summer, I would be going pretty well?
