Server Racks - you don’t interact with them often, but you will need to with the Hydroponics one.
Also, your setup is too clean. Water will drip, spill, the pebbles will fall. Looks really nice, though.
About 5 years ago, I worked with a Climate Research Scientist friend, growing exotic plants in dutch-buckets, tower aeroponics, and rack mounted red-lit setups to induce Vitamin B-12 (only found in meat, so deficiencies develops in vegetarian) to Spinach trying to produce Super Spinash.
Do you have some sort of inoculation step and then use red light to penetrate the spinach leaves to feed light energy to the bacteria?
Worth a mention as many door frames are easier to remove than a number of people might suspect .. fewer pieces to disassemble than many {object}'s and not an uncommon hack when moving furniture.
> Farmers discovered that bright leaf tobacco needs thin, starved soil, and those who could not grow other crops found that they could grow tobacco. Formerly unproductive farms reached 20–35 times their previous worth. By 1855, six Piedmont counties adjoining Virginia led Virginia's tobacco market

This is one beast of a plant. My plants stayed alive when I stopped spraying water in September and only died because of frost in late December. They were about 40 cm high due to the small volume of the root chamber.
Anyway it's a great choice for an outdoor aeroponics setup.
So now I have a new project - I've always wanted to smoke 'pure' tobacco, like the ancients.
I'm twenty years too old to have an illegal harvest at home :)
Next stop, need to check how to cure the leaves.
Thanks!
Sell it?
One setup I had was a vertical (hydroponic) window farm, which looked pretty great, but the roots start to get into the tubing, which I suspect could happen in the rack-mount system too. It also wasn't simple to just take out one plant for maintenance.
A small NFT (nutrient film technique) box has worked very well, requires very little material as substrate and is easy to maintain. Might get problematic if growing the same plants for over a year since the roots can grow a lot and basically partially outgrow the system so the flow of water starts being insufficient and therefore might need at least some trimming and replanting if some of the roots start to suffer.
I'm in the process of trying out deep water culture, which requires even less materials since there's no growing medium, just water, and roots are submerged so doesn't have the same issues as NFT. Probably has it's own problems, though, and air pumps can be loud!
Anyhow, most of my plants are in a passive hydroponics system. "Kratky method" is something a bit similar. I basically replaced soil in pots with clay pellets and manage watering so that I have to water every 2-3 days. Requires clay pellets as the substrate so needs a bit more effort up front, but doesn't require electricity and is more portable when using small/medium sized pots. Pellets can be reused (at least most of them). I also added a short tube for monitoring water level and possible maintenance if I need to wash / flush the pot with the plant in it.
Regarding fertilizing, I rarely do any accurate measurements anymore. I got a few pump bottles and measured how much fertilizer one push gets me and wrote on the bottles how many pushes per litre. I also eye-ball the water color a bit since I know how it should look like.
Oh, and the plants that have done well for me, and can grow for a long time with multiple harvests (so no lettuce): peppers, cherry tomatoes, cucumbers, trying some small strawberries
To be clear, I'm not asking this in some new age way, and I'm sure it's better than the amount of pesti/herbicides used traditionally (and the whole movement behind hydro/aquaponics is fascinating to me), just wondering if this is something you ever tried minimising with such setups?
This is fun!
The following isn’t a knock on anyone doing cool stuff like this: I’ve avoided any sort of tinkering and automation of my gardening because I find gardening to be a slower-moving, meditative escape from technology. My brain shifts into a different mode (almost a flow state?) when I’m out working in the soil and tending to my plants.

Just about everywhere has understood "bread and circuses" and "let them eat cake" to the point of monetarily promoting food production.
One of the big distinctions between feudalism and extreme capitalism in my mind is forgetting this.
The fact that it works at all after a number of years, is surprising to me, given everything that goes on with it: You've got a moist environment with water pumped through it multiple times a day, fertilizer in the water crusting up in places, living plants with their roots growing into the pipes, algae growth, and a lot of parts that are shuffled around often.
There might well be other systems around these days that are the same or better, I wouldn't know, the Gardyn is just what I ended up with when I researched it years ago and I'm happy with it. For downsides, seeds are expensive from Gardyn, but you can plant your own. I do buy some from Gardyn because they have a big selection, and they usually come out good, which regular seeds often don't for whatever reason. They try to push their subscription service but I don't need it, so don't use it.
Hope this doesn't come off as advertisement, as I said there may well be better options (would like to hear about them), but this one works for me for a pretty hassle-free experience.
Then you add the electricity cost and the seeds, and the maintenance time...
But it looks nice in a kitchen!
That said, I prefer growing outdoors if you have the space. It’s a total different maintenance (with way more bugs) but it also doubles as decor better than my hydroponic setup ever could.
You don’t need a $900 gadget to grow fresh herbs, either, of course. But that’s one way you could think of it “recouping” the capital.
In a backyard 5gal/19l bucket, I could get 3lbs/1.5kg of potatoes or 3lbs/1.5kg of cherry tomatoes. The latter is a better deal.
