Description This Clear Propagation Lid fits snugly onto our 15L pots, so they’re the ideal add-on for both the easy2grow kit when using 15 litre pots and our 1Pot system. Simply pot a young plant and fit the lid on top with the vents closed. Over the next few weeks gradually open the vents to harden the plant off finally removing the lid completely during the day. If the weather is still a little chilly; you can continue to use the lid at night. Your young plants will be protected from the elements and will enjoy a healthy start in life
