Why this much soil?How are the recommendations calculated?
To achieve the best results with your organic soil, sufficient room needs to be available
for the roots, microbes, and the food they break down. Smaller soil volumes
can be optimized through supplements but risk nutrient shortfalls if the grow is lengthy.
Even the best soils benefit from supplementation. The calculator uses real-world data,
user feedback, and best practices to approximate your soil requirements.
Smaller pots require higher levels of nutrition-based supplements; luxury pot sizes
benefit from aggressive microbial inoculations to improve nutrient uptake.
