chasv77answered grow question 5 years 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.
