My 20 cents suggestion. The atomizers approach maybe the winning one, almost nearby to something that can be considered a nanoapproach. A nice explanation of the technology evolved on the ISS (they have no alternatives [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-cc22d011-476a-432e-acda-7139c87231e8/contentimage_5F00_3.png:16:16]) is almost well explained in this article: https://www.nasa.gov/feature/the-shape-of-watering-plants-in-space

Creative solution.

Could you use capillary action through a fabric to deliver water and nutrients?

Pretty cool ideas there.

Not that I have any deep space knowledge, but here are a few other water delivery options:

Use a syringe pump, where water is held in a syringe (or other storage device) and pressed out by driving a plunger into the syringe.
Use a water bladder storage (expansion) tank. Water is force in under pressure, and fills a bladder which in turn compress the air within the tank, all while building delivery pressure. This is a common usage as a part of water filtration systems (https://www.expresswater.com/products/tankro-4-gallon-ro-expansion-tank?variant=645922160693&gclid=EAIaIQobChMI5eK-jsPL7…)
Use a bladder that can be filled and then have the water pressed out of it by rolling between to closely spaced rollers. This is similar to the concepts behind a peristaltic pump.

Whatever your delivery method there would need to be a storage device for the water, so why not have cartridge based system that stores the water and then acts as a part of the delivery system.

An interesting approach.
