Help with set up for new arrivals

I will be getting two female BPs soon both about 300g. I won't be getting a male until next year sometime. I was pretty set on the t8 since I'm still not 100% sure about breeding. After talking at length with the person I'm getting the bps from I started looking at racks. Reptile basics had a 4 tub rack with tubs approx 16X24X6 30.5 qt. and a 3 tub rack 17.75X33.5X5.25 37qt. If what I've seen is correct even the 37qt would not be big enough for the females as adults. Would it make any sense to get the smaller one now? What about getting the 37qt now and then upgradeing later for the females and use that one for males or sell it? Or just stick to the original plan and get the t8 for now and look at racks in a year or so If I go that route. The 3 tub rack seems like a pretty economical way to go seeing as how I'd only need 1 t-stat as well.

Also hides and bowls from reptile basics. Planning on ordering 4 med and 4 large hides. Is that appropriate size, and about what size on the bp would they need the large? I was planning on getting the medium crock 6", or would the 8.5" be better? Just want to get things right from the start.

The 4 bin sweaterbox rack would be fine for most of their lives ( I have a few of my larger females 2500 grams plus in these same racks and they are quite happy). They would grow into the medium hides,I dont use hides in my adult racks. I use 3-4 in crocks for water dishes

Thanks, so should I get smalls to start with and mediums for later then? Just want them to feel secure in their new homes. I'm sure being put in a box and delivered fed ex has them stressed enough.

You should be fine going ahead with the mediums
