Cdn source for 6- or 9-cell inserts for propagation trays?
Does anyone know of a Canadian source for the cell-pack inserts for plug trays? What I'm looking for is a re-useable item, in a durable, cleanable, rigid material. The regular black plastic ones are so flimsy and, though I try to treat them carefully, they inevitably split and tear so I can't use them again. Such a waste. More landfill.
I tend to use the 9-cell and 6-cell inserts most. Does anyone know of a Canadian supplier? Any ideas for home-made versions?
