| * Downsides: additional work with caring for animals. Possibly more complex structures - as far as I can tell the animals might not be in a pen in the greenhouse but in an adjacent room with cross ventilation. | * Downsides: additional work with caring for animals.

| * For additional light, low voltage electric lamps (perhaps using salvaged headlights) could do a lot to extend the short daylight hours. Alternatively, [[solar_concentrators|Light Tubes and Fiberoptic Daylighting Systems]] won't extend the length of the day, but they will capture additional sunlight and redirect it into the greenhouse. Light tubes are simpler to set up and maintain but don't reach as far, Fiberoptic Daylighting Systems are more mechanically complex but can reach further and capture more light. Either may be useful if the greenhouse isn't sited as optimally as it could be or just needs more light. | * For additional light, low voltage electric lamps (perhaps using salvaged headlights) could do a lot to extend the short daylight hours.

| * Some of these systems have been tested for indoor farming - could the basic concept of sheltering the growing space into the earth be taken even further and end with a greenhouse entirely underground, with just ventilation and light capture systems on the surface? | * Some of these systems have been tested for indoor farming - could the basic concept of sheltering the growing space into the earth be taken even further and end with a greenhouse entirely underground, with just ventilation and light capture systems on the surface? |
