I believe so, yes.

I put my money where my mouth is and got a basic web gardening calculator up. https://realga.github.io/three_houses/gardening/index.html It's got some rough edges, mostly because I don't really know HTML and CSS that well, but it works for general use.

I have a passing familiarity with JavaScript, enough to write a simple gardening calculator. I'm already writing a gardening brute-force Ruby script to figure out what every possible combination of seeds and cultivation results in, so translation of that should be pretty straightforward.
