Lettuce is indeed your 5¢ balsa wood glider. You can even use sand or pea gravel, no pump, (an air pump is nice at~4w,) and no light source but a good window. Like a 1 gallon fish bowl, you get started toDAY and expand plans and gather materials for an upgrade over the week/month. My fav, although in enrichened soil in a short narrow window box, is green/bunch onions. I get enough for we two for salads or omelets etc, without, non on hand, or them rotting in the fridge because at 79¢, I got 2/$1.

Of course you can start big. But sometimes, genius and joy is in simplicity. Are we not a group of, whatcha got on hand? How simple can it be made? Turbo charged monster bikes are ok – but what charm hath a crude brewed mini-bike? And, face it.. most of use could up our lettuce. Small is tender and tastier. Kids are wowed. Miniature indoor gardens! Suddenly it’s; I wanna taste! Build a huge rig and it’s all; “Hey- hands off!” Start small and you can start today. Tonight. This very hour.

Human waste as compost has the trouble that you are likely to cultivate large populations of human pathogens unless you handle it very carefully. This usually means running a very well managed compost heap that makes heat and sterilises itself (Which will also kill weed seeds, so if ppl tell you not to put weeds in your compost, they aren’t running their compost right)

*exclude light

Good idea with the overflow protection. I regularly check the reservoir, so there’s little risk of it occurring, though. Also, there’s a lid for the reservoir to explode light to reduce algal growth, so no chance of leaves falling in.
