You will need someone other than me to respond, Ben.
I want to express a caution, however. Consider the choice on the best advice you can find, especially if most of your garden plants will be from your indoor starts.
A wrong choice of soil mix to start seeds nearly ruined my gardening year quite some time ago. The starting window is narrow here and I had to do some real scrambling to begin anew, after a couple of weeks and the soil problem became apparent. I immediately lost track of the name of the product but it came from Ace Hardware and had this great price. It had a cheerful daisy printed on the bag - I never saw that logo again and suspect that I wasn't the only victim of a poor choice.
For years since, I have stuck with the same product. I'm sure it's not the best - for one thing, it's too coarse. Risk-averse and burned once, I'm just not willing to experiment.
