For some reason, indoor hydroponic growing, even on an industrial level, is still extremely DIY. You have to buy a grow tent and assemble all the necessary components.
Why not simply build a ready-to-use box that contains everything you would need for your growing operation?
These boxes could come in different sizes according to your needs, but the core elements would be the same. The panels would be made with LED/UV lights equipped with timers. It would have a simple ventilation system. The bottom would be a normal hydroponic planter like this -
It could be equipped with a humidifier and a dehumidifier and even measuring systems like thermostats and humidistats that could test the air quality, light quality and temperature at all times.
I'm sure there are many more elements that could be added. We could even write software that allows you to control all of it from your smartphone.
The point of this idea isn't to think of all the features such a box could have though, it is simply to show that it does not exist yet. Thousands of people are growing plants indoors and essentially building these systems themselves at ridiculous prices, why not produce a readymade system for them to buy?
The entire box could run off a single power supply, it would be much more transportable than a system in a tent, because you would only need to move one solid item, it would be neat and it would likely be more accurate than DIY systems as well.
I really am amazed that I haven't been able to find such a system anywhere. IKEA has the iGrow, but that is just a lightbox for plants, essentially. The Aerospring seems pretty complete but it is actually just a collection of everything you need to build your own setup, it still requires assembly and you could probably source all the different parts yourself and build a better system for less money. The best I've seen is the iHarvest, but it is not a closed system and therefore doesn't allow for precision gardening, but it does have a lot of the functionalities I invasion for this idea.
