My experience with MG soil is limited to just their potting mix and Moisture control potting mix. They both contain slow release fertilizers which can cause you problems with your plants, especially seedlings. Too much fertilizer can cause plants to become stunted in their growth. They both have a tendency to compact down and retain extra moisture, the moisture control even more so. The mix is also not as light and airy as some of the better mixes, which slows down root development and root health. It does work, and you can get a decent harvest from your pepper plants, but just know that your plants would be a little bit nicer if you use a better mix.
For seed starting the regular MG potting mix will work. Even with the "chunks" the seeds will sprout, but you may loose a couple because of the additional fertilizers.
