🪴 Nutrients

How to fertilize Walstad

Nutrient, fertilizer, and repotting needs for Walstad: repot after 2X growth

Most potting soils come with ample nutrients which plants use to produce new growth.

By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.

To replenish this plant's nutrients, repot your Walstad after it doubles in size or once a year—whichever comes first.

🌿 Ecosystem — Day 15 5 days ago, I kickstarted the nitrogen cycle. Since then, the process has followed a textbook progression — ammonia appeared first, followed by nitrite, and now nitrate, confirming active nitrification. A mild algae bloom has emerged, prompting me to slightly reduce the photoperiod to restore balance. The plants are stabilizing, with some melt still visible but new submerged growth starting to appear. Overall, parameters are stable, biofilm is forming, and the ecosystem is transitioning from chemical cycling to biological equilibrium. #HappyPlants #Aquarium #AquaticPlants #ecosystem #ScienceWithGreg #NewGrowth #MentalHealthMatters #ADHDPLANTLOVERS #PlantTherapy #Hydrocotyle
