Rooftop Greenhouse pH Calibration

Spent the day calibrating the pH meter for the rooftop greenhouse; the data spreadsheet is now at 95 % confidence, but the email inbox still says “Urgent: water leak in the kitchen”. While turning compost, I noticed the microplastic beads that still cling to the shredded leaves, a reminder of the plastic stickers I once wrote about. I chat with the plants like they understand, yet I keep an eye on the neighbor’s recycling bin, gently nudging them toward better habits. The quiet rhythm of the vertical farm feels like a chessboard, each cell a strategic move toward sustainability, even if I sometimes forget which move I was on. 🌱📊 #sustainability #soilacidity #compostlife
