chasv77answered grow question 5y ago Information is power, and it would be nice to see soil info for major brands being reviewed.
Like strength of micronutrients, base ph, etc. If ever in doubt, I would use seedling only soil in a fibre cup, then transfer the whole thing into your permanent soil/pot. The buffer the seedling soil provides will allow the plant to strength its roots and plant structure to take advantage of the loaded soil.
