I think you will find that the formulas and favorite soil mix brand/recipes are so numerous! And in reality, I think that just about any soil-less seed starting mix, in combination with appropriate amount of moisture and favorable temperature work perfectly fine! Some starting mixes are finer than others, some easier to get moisten and keep moisture a little better... And what you bought should work just fineImperialboy wrote:...
- 1. What soil do you guys usually use for seed starting? (I've been using store bought organic seed starting mix)
2. What soil do you guys use for adult plants? (After the seed starting mix)...
But since you are asking what others use, I personally, I prefer Espoma organic mix, I do believe that their Mico-Tone (with micorrhizae) has very positive effect on seedlings vigor and rood development. I also add worm castings to this seed starting mix to provide additional nutrients that in my observation make very noticeable impact on the size and growth rate of the seedlings and their root system. Again, this is my personal preference.
Potting up the seedlings (before transplanting them into the garden or containers), I like to use Espoma Potting Mix, but I do add sand and mushroom compost to make the mix a bit more denser, and still add worm castings as well.
Containers - again, there are as many preferred mixes as gardeners themselves (or just about). I personally find that Sta-Green, specially the blue packaged, mixed with addition of mushroom compost, worm casting, lime and home made compost and extra vermiculite works just fine. And I do re-use the potting soil.
At the end of the season, place all the container used soil in compost bin, and add organic matter throughout the fall/winter, then at the planting time, just adding more mushroom compost and home made compost and lime again.
