There are lots of good books on it and youtubes. It largely depends on what you want to grow. Fruiting plants are different than leafy plants, for example.

I suggest starting with a nutrient blend like this: https://www.amazon.com/MasterBlend-4-18-38-Tomato-Vegetable-...

You can look up the ratios of the elements for different plants on the web. It's all out there. mhpgardener on Youtube is amazing https://www.youtube.com/watch?v=nXy32Dr4Z4A He has videos on how to set up different types of hydroponic systems, there are 3 main types, the video link is to an Ebb and Flow system called Dutch Buckets and is mainly used for fruiting plants like tomatoes, eggplant and peppers.

There's also Nutrient Film Technique (NFT) which is more like what you see in PVC systems that pump water along the roots of the plants. There's also a raft system where the plants float on top of the water and the roots are constantly submerged.

I looked at Aeroponics too and I believe that is an excellent system as well, though did not try it.

Watch mhpgardener's experiments with different nutrients. He does one with organic nutrients, but they didn't grow as well as the masterblend recipe, which you can learn about here: https://www.youtube.com/watch?v=vYv9iu2NI3M

I remember watching a video about a Japanese company that can tweak the flavor of different herbs to exactly cater to what their chefs wanted to accentuate different notes for different dishes.

For equipment, you'll need a pH meter: https://www.amazon.com/Poit-Digital-Meter-Tester-Resolution/...

a PPM meter for nutrient concentration: https://www.amazon.com/HM-Digital-TDS-EZ-Measurement-Resolut...

The rest depends on the setup you want and the plants you want to grow. What do you want to grow? I can point you to a good kit to get started. Here's one for dutch buckets on amazon, real cheap. https://www.amazon.com/Deep-Water-Culture-DWC-Hydroponic/dp/... You could grow two tomato plants in one bucket and get 20-30 pounds out of it in one season very easily.

Pretty much anyone here can do hydroponics. It's like programming plants!

And they do not taste like grocery store hydroponic veggies. Those are grown to meet other priorities: thick skin, shelf life, uniformity, color (sometimes). They are not concerned with flavor or nutrients.

In your home, in your yard, you can prioritize any aspect of the plant you want, what's important to you: Flavor, Nutrients, Color, Size, harvest dates.

They are all just numbers. It's not that hard. It's not easy and you have to care but it's the same as anything. If you care and you want it, you can do it. I know, because I did and I want more people to know they can too.

YOU CAN!



Thanks, very interesting! I'll take note, and start playing around when I have more space in my apartment :)

I'm generally interesting in hydro-/aeroponics from the perspective of growing plants in space, via, as you mentioned, "programming" them - basically, what's the minimum of nutrients (not just minerals, but also water, air and sunlight) that's needed to grow food (and air) for people.

I also thought about actually programming plants, I wonder if there's any research in this direction - e.g. why do I need an orange plant to grow a trunk? If I could inject the right hormones at the right place, I could skip all that and just have it grow leaves (energy production) and fruit (energy consumption) without any other superfluous parts.
