Substitute for Park Bio Dome Plugs?
As opposed to last year when I went overboard in starting seeds, I am doing much less this year and (obviously) I am late to begin germination in my Park Bio Dome. I ordered refills on Mar. 18 and over 2 weeks later I see they are "shipping soon". I am afraid they may be backordered and haven't told me yet. Without getting the plugs, I probably can't use my Bio Domes, so I'm looking for surefire ideas to start my veggies and a few flowers. I have a heat mat and grow light; will start them in my basement and move to my (unheated) greenhouse when it warms up a little more--we still got snow 2 days ago here.
Thanks for any suggestions!!
