This was my first year having many clutches( last two years I only had a couple of clutches) so I needed something better than just a couple of tanks. I bought an industrial shelving unit and built racks into it. I wired my light fixtures to the particle board. I bought identical totes to house the babies. During the first week/two weeks after hatching, I used paper towel to hold more moisture. After that, I used no substrate and found it easier to clean/feed that way( nothing can hide). I use a spray bottle to mist a couple times a day and give frequent baths. I can also put a 75 gallon tank on the shelving unit bottom.
I used a digital mini fridge this year to try out, I wish they were more spacious but had a really great hatch rate with it( it did fluctuate 3-4 degrees from top to bottom though). Vermiculite is the medium I use for the eggs.
Next year I plan on trying to make any improvements I can think of
