Yet Another Manifold

Built my latest manifold for watering house plants. It’s smaller, with 5 zones controlled by solenoid valves; each zone can have 8 adjustable drippers. We can adjust the duration and frequency of watering for each zone via the Web.

Indoor Farming Experiment

Used grow lights for the first time today. We’re still experimenting, but the plan is to produce a continuous supply of microgreens and herbs. The white rectangle in a small zippered bag wirelessly logs light levels and surface temperatures in a spreadsheet.

Winter Preparations

Prepared for winter. Took down the irrigation system I’d built for our balcony plants. Gave the 250 feet of tubing and 48 drippers a shower.

Balancing Act

Successfully prototyped a pressure balancing system for watering indoor plants. The highest plants are over 6 feet above the lowest plants. I was able to adjust the system so that each dripper gets similar water pressure.

Plant Controller

Completed a controller for our indoor plants. We can control irrigation and three sets of grow lights over the Internet. The controller turns the water pump off when the tank is almost empty or the Internet goes down (after a preset number of minutes).
