FAQs
Is Pro-Mix soil?
It’s more of a soilless growing medium — usually you add nutrients/compost depending on your goals.
Why high-porosity?
It helps prevent soggy roots and improves oxygen around root zones.
Do I need fertilizer with it?
Typically yes — plants still need a nutrient plan.
Is it good for seedlings?
Yes, commonly used for starts when managed with appropriate watering and feeding.
