I am in the process of developing a special greenhouse that may solve your space problems. Here is a picture of prototype #2 . Uses the most efficient LED from an American company, equivalent to roughly 1000 Watts incandescent with only 160 Watts. we control the temperature, the humidity, root temperature, moisture level, light intensity, spectrum, light on off timing etc. It also has root moisture alarm in case you forget to water (it will either be a text message or message on your app...TBD). We are finalizing the hardware design in 4 weeks and currently refining the firmware and then the user interface which will be about 8 weeks total before we start to ship. The system also filter the air coming in and coming out of the system. Everything is controlled from an app and you can either select what you are growing and hit "go" or you can customize you own settings and save a custom growing setting.
We will be retailing this for somewhere between $1,199 and $1,499 (still TBD) but I was going to offer it to F4F members at a special price ~ $799, if they help us spread the word. It has good aestethics and most people wont mind having it in the house. Completely light proof and you cannot tell it is on at all. I will offer it in the Light Brown as shown but also in Hunter Green. Everything inside is heavy duty with several redundancies and safety margin on the critical items. If you are interested, let me know and I can keep you posted as we get closer to releasing the product.
