There's a small industry already making plant growth chambers.[1] There are little desktop ones, refrigerator sized ones, and bigger ones. You can get LED lighting, temperature, humidity, airflow, water, and C02 control, networked computer interfaces, and data collection software. Basic tool in ag R&D. They look a lot like the "food computer", but with better environmental controls and insulation.

Not usually used for production; once the desired conditions have been figured out, the production system can be simpler.

It, ah, looks like Conviron's smallest unit is still a little larger than a typical full-height fridge - and that one's really new, having only been announced in April this year. (Reverse osmosis system not included.) Doesn't look as well insulated as your typical fridge though. All the other ones are even bigger. They're not really comparable - or doing the same thing, given that the PFC was hydroponics-based.
