What is best seedling plug manufacturer?
Looking through plant and seed catalogs, I've noticed companies are selling plugs for growing seedlings, made from composted bark. The plugs are spongy and hold their shape. They supposedly hold the right amount of water. My questions: who make these plugs? Park seed company sells their variety. Gurneys sell a variety. There is the Q-plug, Peaceful Valley sells or makes their own, plus several other companies sell similiar products. Which plug is the best and gives you the best seedling quality?
How do you use the plug you buy? Do you grow the seedling to completion in the plug? Any other advice would be appreciated.
