Hydroponics 101

This week I’ve been prototyping systems for maintaining water levels while rooting plant cuttings. This morning I built a “production” system that includes a float valve connected to a water supply to top up the tank automatically.

Science Experiment: Siphonic Action

The problem: maintaining water levels for rooting cuttings while we’re away, traveling. The solution: siphonic action. The blue container represents a reservoir that will be topped up via a float valve. Prototype 1, here, has too many points of failure. Next up: straight runs from the reservoir.

Plumbing Plan

Met with two members of our building’s garden club to plan improvements we’d like to the irrigation on a roof deck. Updated a document that will be part of a request for quote. We were treated to delicious home-made scones, and I left with three more for later.

Sunday Ablutions

On Sunday mornings houseplants receive extra care and attention. Here, they’re lining up to take a gentle shower. All the plants happily survived six weeks of drip irrigation while we were in California.

Remote Plant Watering

In Minneapolis I lay on the couch, grouchy, nursing a cold, periodically flushing out radiation. From Palm Springs Dwight remotely watered our apartment garden. The plants look good to me, but doubtless he’ll see issues when we both return to Minneapolis at the end of the month.

Apartment Garden at Sunset

On Sundays, Dwight makes sure all the plants are properly watered. Most of these plants have automated watering and misting. Plants in other areas are watered manually and get rotated through this area.

Quality Control

Walked around roof decks with Dwight giving planters the finger test to verify they’re getting enough water. Plants are thriving, thanks to our building’s gardening club.

Shrub in an Ocean of Mulch and Lawn

Admired a modest shrub Dwight had transplanted for our building’s gardening club. We support replacing some lawns and mulch with native grasses and other plantings, but many of our neighbors probably prefer things as they are.

Time to Water the Plants

9:30 a.m., Salema, Portugal: Dwight watered all the houseplants in Minneapolis where it was still night. Misters are on autopilot, but he prefers to run watering zones manually. The system has been reliable, but I find myself imagining additional fault-tolerant features to minimize the possibility of returning from a trip to racks of dead plants.… Continue reading Time to Water the Plants
