Regarding indoor hydroponics...

Most of my power consumption is through my grow lights (still way cheaper to grow than to buy at the grocery store).

I've thought about solar panels and batteries etc... but that costs a lot of money (I havent found a non-scam solution - still researching, but let me put this down for a second).

So I started thinking... instead of lining my roof or side walls with solar panels to power indoor LED grow lights...

...why not just install light collectors outside and funnel that light directly into my house and on too of my plants with fiber optics?!?!

Basically run cabling through my house to wall literal light sockets. And attach further cabling from there to my plant shelves and setups. I could still have LEDs for augmenting the grow space if needed or during stormy days for example... but even then there is light to be collected. Anyhow!)

Turns out other people have the same idea!

Here is a gentleman going a into detail on the math and science of it with a DIY project: m.youtube.com/watch?v=DN8GXTmR

There are even some companies that do this!

Here's the basic idea (I stole this pic from solarreviews.com/blog/guide-to):

An illustration showing a house cutaway with the sun shining on a clear day. A collector sits on the root. Fiber cable takes the light from the collector and moves it through the house to an illuminator.

@yohan_q - Absolutely! Low cost, low maintenance, hands off passive / automated hydroponics:

Read here for a proof of concept bin build: infosec.exchange/@tinker/11216

And here for a larger "kitchen garden" build: infosec.exchange/@tinker/11143

Basically using the Kratky method. See here: kratky.weebly.com/

So you provide as much water as the plants need (for leafy greens) or set up a passive system with a reservoir and float valves (for larger more water intensive plants. See here: kratky.weebly.com/bigger-plant

No pumps, no aerators. Lights are on a timer. Mix nutrients and water. Plant the seed and ignore until its time to harvest.

Infosec ExchangeTinker ☀️ (@tinker@infosec.exchange)Attached: 1 image My "Single-Unit Hydroponic Grow Bin" 2.0 This thread will show how to build the grow bin and then follow along for six weeks as the example veggies grows. (This is an upgrade from my proof of concept found here: https://infosec.exchange/@tinker/111321153719012419) The goal of this grow bin is: - To be small enough to fit in most places (the diameter of the base is 7 inches). - To be self contained with everything needed to grow a plant. - To be passive / automated / hands off - plant the seed, wait six weeks, harvest. - To be exceedingly cheap (with bulk supplies, the individual unit cost comes out to about $10) - Not require a lot of maintenance. - To be simple to make. - To be powered by a wall socket or USB battery (for folks charging batteries using one off solar panels). This answers the obstacles of hydroponics being portrayed as requiring an expensive startup cost, having dedicated or expansive space for hydroponic growing, require special or complex equipment, or special knowledge and skills. IT'S ADHD FRIENDLY!!!! Start growing whenever you get around to it. Doesn't require following growing seasons. Once you start growing, you can forget about it until it's done growing. This grow bin utilizes the Kratky method of hydroponics. (See how-to build in following thread.) #solarPunk #hydroponics #indoorGardening

Trouble with my hydroponics!!! Oh noooo!!!!

So, two of my crops failed to germinate in the bins (I'm seeding directly from the bins and not germinating separately / planting into bins after they've sprouted).

This was weird. - Four of the other crops germinated just fine.

So what's going on?

Got to thinking. I put water in from a different tap. Same water... right. So it's not a pH issue, etc. But the water was COLD from this other tap. Like really chilly. Whereas the four bins were filled up with warm water.

So I'm thinking, maybe the temp was too cold for the seeds to germinate.

I've started over, this time with warm water. Will watch if that helps. We'll see!

Six bins. Four have germinated. Two have not. WHY?! OH GAWD WHY?!
