I've never done a bioactive setup myself, but they are beautiful and intriguing. But here is another Tumblr blog you can have a look at that has a lot of information and references about enrichment and its benefits for snakes and other reptiles.
One thing that may factor into your plans, for what it is worth: Even people who strongly recommend enriched or bioactive enclosures often still recommend simpler enclosures for the first few weeks or months (or for the duration of quarantine, if you have other reptiles) for animals new to your household, so that it's easy to tell in case they have mites or other illnesses. It doesn't have to be a completely bare tub with nothing but a hide, a bowl, and a paper towel; but simpler than a fully planted viv. So you could start out with a simple setup in a tub while you work on the fancy bioactive setup, and then move the snake in once the plants are established.
