The Kratky Hydroponic Lettuce Wall will be comprised of a couple of things:

1) A utility shelf with adjustable shelving
2) Full spectrum LED "grow" light strips w/ timer
3) Grow bins

That's it.

The utility shelf can be broken down into the following requirements:
- DANGER!!! WARNING!!! IMPORTANT!!!: The shelves should be able to actually hold the weight of your grow bins. Water is heavy. Many shelves by themselves cannot support the weight of the water and will need support. So check the weight rating on the shelves you get. We'll continue to talk about this further as we built out the shelf.
- ANOTHER DANGER!!! WARNING!!! IMPORTANT!!!: You need a way to anchor your shelves to the wall SECURELY!!! You don't want this thing tipping over. You build it too high and it falls on your kid or dog or cat and they may die. Secure this to your wall. Especially the higher you build it.
- Shelves need to be adjustable to allow enough space for the bin to sit and for the plant to grow
- A way to attach the light strips to the shelf above the grow bin
- Bonus: Make it pretty

The Grow Light Strips can be broken into the following requirements:
- They should fit the length of the shelf you pick and be attachable to it in some way
- You should be able to control them with a timer (either on the light itself or set up with a wall socket timer
- Have a method of increasing the light or decreasing the light (easily add more light strips if needed, or adjust brightness, etc)
- Be full spectrum "grow" light. Note: it does not have to SAY grow light. Sometimes lights are like cakes. A regular white cake is cheap. Add the name "Wedding" to that same cake and it gets expensive. As long as the LED light strip generates enough light for a plant to eat, we're good.

The grow bins can be broken down into the following requirements:
- They should hold water.
- They should be fully opaque and not allow any light into the bin itself.
- They should hold some sort of grow medium to allow a plant to grow on top and provide access to the roots to get into the bin to access the nutrient water
- Bonus: Make them pretty

That's it.

No pumps.
No aerators.
No central reservoir.

Just a place to put a kratky bin and grow lettuce.

We'll tackle how to size and shop for a utility shelf next.

. @kechpaja - Au contraire, my friend!!!

Prepare yourself for a lengthy rebuttal! (And thank you for the opportunity to info-dump on you!)

So this *is* an example of post-scarcity infrastructure. But how and why?

High Level Definition of Post-Scarcity Food (so that we may agree on terms): Post Scarcity is where we produce more food than is consumed and distribute that food out. It can be universal or local - so unevenly distributed post-scarcity or the fact that one area has it and another doesn't, does not imply that post-scarcity in the place that has it does not exist.

Great.

In the *pragmatic* sense: Post Scarcity Food needs inputs and outputs. Contributions and Distributions.

Overview:

*Current* Contributions / Inputs (read: not ideal, not what is being built or hoped for, but how it is right now):
- Charity (which you reduced food rescue and free fridges down into)
- Food Rescue (not charity... not even mutual aid)
- Mutual Aid

Current Distributions / Outputs
- Centralized
- Decentralized
- Peer-to-peer

Detail:

Contributions / Inputs

- Charity: Examples of this include food drives, food banks, church food pantries. Charities are not ideal and often have conditions tied to them ("Means Testing" and the like). They rely on "people being kind and generous" as you put it. If all we had was charity, we would not be in post-scarcity. While charity is often a cover for artificial-scarcity (our current over-arching economic model), it CAN be used as an input into post-scarcity. You just can't rely on it and need to build it further infrastructure. I use it because its there, but it's more of a transition thing.

- Food Rescue: Food Rescue is not Charity. Food Rescue is not Mutual Aid. Current Food Rescue relies on a capitalistic model. A for-profit store/restaurant/bakery/etc makes food to sell. Cannot sell all of it. Instead of throwing it away, it "donates" the left over good food to be consumed elsewhere. Food Rescue is NOT out of the goodness of a corporation's heart. Corporations do not have hearts. They cannot be kind or generous. Instead, Food Rescue is applied to the bottom line / profit margin and is justified by things such as "lowering the fees for trash" and "having a tax-writeoff to a non-profit (again within a capitalistic system). But! While Food Rescue is not charity and relies on the current capitalist system, it absolutely shows that we produce MORE than is consumed. Ironically, an example that we have the MEANS for post-scarcity. I use it because its there and is a ready source of feeding people. While I push for post-scarcity, I care about feeding people *now*.

- Mutual Aid: This is the ideal and the model for a full post-scarcity economy, and we're already building this out. Community Farms / Ranches (Centralized), Community Gardens / Local Small Scale Ranches (Decentralized), and Home Gardens / Home Ranches of various forms (peer-to-peer) are ways that we produce for ourselves, our neighbors, and our towns. This is post-scarcity mutual aid and does not rely on the people being kind and generous. It relies on us taking care of our neighbors AND ourselves (call it selfish if you like). Mutual means mutual.

Detail:

Distributions / Outputs

- Centralized: The charity model uses food pantries / churches / mobile pantries to distribute out food from a food bank. We can utilize that now, but we are absolutely not (nor should we be) limited by it. Instead, Free Stores are the Centralized model of post-scarcity mutual aid.

- Decentralized: Free Fridges & Community Pantries - This is where my fridge above fits in. It's not charity by any means. It's a node in a distribution network.

- Peer-to-peer: The simplest form of this is one person handing it to another. A neighbor asking for sugar. Handing off your extra squash on your street corner. You can scale this up using things like mobile apps such as Olio to coordinate this across larger areas.

Great, so we laid out inputs and outputs for post-scarcity food.

To give a specific example, see this post: https://infosec.exchange/@tinker/112582425833711424

There I show how I used the Input of a Mutual Aid Home Garden and the Output of a Decentralized Free Fridge.

None of that was charity. None of it was "kind and generous". Instead it was building the infrastructure for post-scarcity mutual aid that I use myself.

I take from the free fridge all the time. I drop off at the free fridge all the time. I produce for the community. I consume from the community.

We have the tech & the means. We have built infrastructure already (see the original post). We are now scaling it out.
