Starting my first grow first baby girl just popped, I have heard that mg potting mix is great for first media, but how long can I use it or even finish with it??
The soil you choose to use - use thru your whole grow. Potting mix has more “things” init to help promote growth, potting soil is what it says just soil. there are some great mix’s’ out there. want some names of?
Never thought about it but I use soil and mix with a few other ingredients.
