Happy to answer your questions.
My biggest customer is in Hawaii. Climate is humid and hot. They go through a ton of Worm Inns. Is there a difference? Yep…You’ll need to water less often.
Heat is less of a factor with a system that breathes. Even so, if you place a worm bin in direct sun, you turn it into a frying pan and the bedding will heat up.
Smell comes from anaerobic bacteria. Cut off air flow, and you’ll have smell. If you soak a towel and plop it on a table, it will stink as no air can penetrate the mass. In this situation, there is no containment system, so the smell is not due to a sytem. Likewise, I can create the most breathable system in the world, but if you get too aggressive and soak things too much, you’ll create issues. If you properly maintain your system…no issues.
Quickest way to get castings? Simply a function of worm mass. Anyone that tries to tell you differently is lying to you.
I keep a bucket under my Inn, but rarely have any water in it. If I choose to overwater, I will get some drips. Your choice. If kept on a carpet or something that could stain, I would suggest using a bucket.
Veggie and fruit pulp is fine….but here is where things can get tricky. You can juice a large bag of fruit/veggies into a small dense mass. Even though you removed the water, you still realistically have juiced a LOT of matter. The Worm Inn can process a lot of waste, but you should only put an amount that your worms can eat within a few days…or you will create a problem as the juiced material starts turning into vinegar. Normal rotting fruits and veggies break down slowly enough in the Worm Inn for the worms to keep up with their decay.
