Park's Windowsill Greenhouse Refills

Starting from seed is so easy and fun with Jiffy Windowsill Greenhouses, and now you can re-use your greenhouse by stocking up on these economical Jiffy-7 refills. Just add water and these compressed peat moss disks expand to become a pot and soil all in one.

Jiffy-7 disks are so easy to use. Each lightweight disk is pre-drilled with a planting hole. Just soak them in lukewarm water for about half an hour, then place a seed or two in each hole. Jiffy is a trusted name in seed-starting media, and you can count on these disks to be reliable and high-performing.

You get 36 disks in this refill pack, enough to start the garden in style indoors. These 36mm pellets are the best-selling size because they allow more plants to be started in a smaller area. 72 of the 36mm pellets fit a standard 10" x 20" plant tray.
