Ok, so the green house acts like an indoor place but allows growing.
But what about adjacent to windows? Aren’t they viable if you have plant pots. Green houses and plants do have the disadvantage of needing to be watered, but have a higher output than out door plants (less plant diseases and pests, because of the closed environment).
I would like to expand on the indoor plants, by possibly adding hydroponics. It wouldn’t be surprising that in the next 10 or so years that we will grow a lot of plants using hydroponics since it is more efficient, so they should be relatively common, and the parts needed to create them e.g. PVC piping, pump could be found in hardware stores.
Hydroponics would need:
Metal frame (racks)
Planting containers (plant pots, cut bottles)
PVC piping/pipe
50L of water
Plant Fertiliser X 5
Tools needed, screw driver, hack saw / equivalents of previous.
Light would be needed, but daylight would be fine. And the temperature could be maintained by lighting a fire in the room. The fire could also be a light source, so you could make your Evac Shelter basement into a hydroponics store.
But I my self would like to be able to make a bio generator where I can put wood in, and get energy out, so I can have lights in my house.
(By the way, the bananas we eat are sterile, and every banana is a clone of each other)
