Earthbox Soil/Mix -- So confused!
Hi all, I just made a homemade Ebox and have a real one coming as a Bday gift. I've been reading a lot of info about potting mix (since apparently I don't want to use potting soil in an ebox?). There are many brand recommendations in this forum and on earthboxresearch.com, but unfortunately I can't find any of them in Los Angeles.
I've been to Wal-Mart, Lowe's, 2 Home Depots, OSH, and a local nursery, the only "potting mix" I can find is Miracle Grow. That might be okay, but it says that it feeds the plants for 3 months, so if this potting mix is okay should I not add a fertilizer stripe to it?
I did also find Sta-Green Container Mix, is that the same thing as potting mix? It apparently has enough fertilizer for 9 months so I have the same question about whether that is okay for the Ebox and if so should I just not add a fertilizer stripe?
I've seen some people recommend Supersoil Potting Mix, but looking at their website it doesn't look like they make a product with that name. They do make a Supersoil Planting Mix and a Supersoil Potting Soil, would either of these be the right thing? My Lowe's has both of those.
Thanks for taking the time to help out a completely confused newbie!!
