Three months ago I planted broccoli. Anyone in the world can water it with Nano now.
Hey r/nanocurrency. I started NanoGrove three months ago when I transplanted broccoli seedlings into a raised bed I built in my backyard in Richmond, Virginia. They've grown alongside the project the whole way. The heads are golf-ball-sized right now, hitting their final swell, about two weeks from harvest. The plan is to donate everything to Feed More, our regional food bank.

Every XNO transaction above 0.1 Ӿ opens the solenoid valve, sends water through six drip lines, fires a full LED sequence across the bed, and dispenses seed for the birds from a wall-mounted cereal dispenser. Anything below 0.1 Ӿ goes straight to the treasury as a tip. Every transaction expands the grove to fund the next bed. One season, one harvest at a time.
The whole system runs on a Raspberry Pi 4 with a capacitive soil sensor, flow sensor, ADC, level shifter, and a 12V relay board driving the valve. When soil moisture drops below 30%, automated soak cycles handle baseline watering, and the system skips them when rain is forecast.
Broccoli is a fussy crop. Too hot and it bolts. Inconsistent watering hollows the heads. Richmond's spring window before summer heat arrives is tight, so this first season has been a live stress test for both the grove and the automation.
Three months in, two weeks to go! Thanks for taking a look.
