Not to sound like a broken record (there I go - dating myself) but why use any container at all? I use soil blocks for just about everything. Once you've got the equipment you don't need to keep on getting or finding anything else, and there is nothing to contribute to some landfill when it's used. Transplant shock doesn't exist, because roots are never disturbed and they never get root bound. Bottom watering, the preferred method, is simple, just requiring a dunk, tray by tray. Granted, the blocker is pricey, but it's a lifetime investment in superior growing, or at least starting.
