What seeds are you starting indoors? Tomatoes? Peppers? Your favourite flowers? Have you considered growing your seedlings in biodegradeable, earth friendly newspaper pots?
Our paper potmaker, the N.ViroPotter (enviropotter) is easy to use. You can make as many seedling paper pots as you need when you need them. The paper pots are strong and stay intact from initial planting until transferred into the garden.
