First purple sweet potato flower of the season, a beautiful milestone and a timely warning. Flowering coincides with shorter days and cooler nights, which push the vines toward senescence: leaves will start yellowing, drop off, and growth will slow dramatically.
For our 2025 Bitcoin Mining Heat Capture greenhouse, that means it’s a critical time for the concrete floor upgrade. We’re going to pour a concrete slab with a rubberized barrier and insulation to prevent conductive heat loss into bare soil. Without it, the ground acts like a massive heat sink and wicks away precious BTUs from the Bitcoin heat capture greenhouse. This weekend is all about slab prep and installing a proper drain. Mixing and pouring the concrete will most likely take place on Monday.
This flower bloom is on one of our mother plants. Mother plants are your year-round insurance policy, keep them healthy and protected, and you can always take cuttings to restart a crop.
What’s timely now is pouring the concrete slab, moving all the plants into the greenhouse, and restoring springlike conditions. We’ll simulate spring with Bitcoin mining heat and supplemental lighting to maximize productivity. With this setup, even in 0 °C in the worst of winter conditions we can grow food as if it were peak spring or summer, faster than ever.

Fun fact: Our Purple sweet potato flowers are diurnal: they open in the morning and begin closing by afternoon. By later today, this bloom will be mostly closed and easy to miss.
