Episode 8: EarthBox Top Dressing, Soil Nutrition Management & Preparing for Flower Transition

In this episode of the BuildASoil 10×10 Series, Season 9 Episode 8, I walk through a real-time update inside the 10×10 grow room as the plants push into a critical stage of development and preparation for flower.

I start with a full Week 8 update inside the EarthBoxes, showing how the canopy has filled in and how plant health is responding to recent environmental and irrigation adjustments. This sets the stage for dialing in nutrition right before the flip.

From there, I break down a strategic top dress application for the EarthBoxes, explaining how I build soil fertility using slow-release inputs instead of force feeding liquid nutrients. You’ll see exactly how I prepare the soil surface to support feeder roots and maintain steady plant health through the transition into flower.

I also go step-by-step through the EarthBox top dress recipe, including Build-A-Flower, Craft Blend, Kashi Gold, and how I integrate Rootwise biology to activate the soil food web. This section focuses on timing, balance, and why less intervention often leads to more stable growth in living soil systems.

Finally, I explain how I prepare the system for flower transition, including moisture management, microbial inoculation, and how I think about supporting plants as they shift from vegetative growth into reproductive growth.

By the end of this episode, you’ll understand how to properly top dress EarthBoxes, how to prepare living soil for flower transition, and how to maintain plant vigor using biological inputs instead of synthetic feeding schedules.
