Last time I encountered this on the network, the hot thing was self-contained 55-gallon plastic drums, with integrated thermal signature hiding and odor control. You plug it in, add water and hydroponics chemicals, and mostly leave it alone until ready for harvest. But at the time I saw it, the electronic control systems were largely do-it-yourself, rather than turnkey, off-the-shelf control units.

By this time, there should probably be a package targeted for Raspberry Pis, and the ability for your cannabis plant to text you via Signal if she wants some attention.
