Lettuce Grow Farmstand

A stackable hydroponic tower for 18–36 plants, indoors or out, that self-waters and self-fertilizes from a pump in its base — you plant pre-sprouted seedlings ($2.99 each) instead of germinating seeds, so it skips the failure-prone step entirely. The app is free and nothing is paywalled; ongoing cost is seedlings and nutrients, not rent. Vertical growing at standing or seated height, no kneeling, no digging. Pricing runs roughly $530–$650 by size (the indoor Nook is $649; the Glow Rings light kit for indoor use is $399) — confirm the current tier at the official store.
