Propagation Supplies

The best flowers and vegetables start with the best seed and best propagation supplies. Harris Seeds offers you a vast line of plant propagation supplies including propagation trays, humidity domes, peat and plastic pots, rooting hormones, and more.

Growing seed in the proper sized container is key. Starting items like tomatoes and peppers in 50 cell, 84 cell or 144 cell plug traysinstead of 288 trays or 512 trays can give you large enough plants to transplant directly into the field without having to transplant them first into a larger cell or pack. This can save a lot of time and labor. On the other hand, if you plant really small seeded flowers into large cells, you may have a tough time getting them to germinate and develop a strong root system. So it's important to choose a cell size to match each plant's needs. Jiffy Peat products are great for starting seeds and for transplanting plants directly into the field. Because the roots are not disturbed while transplanting with Jiffy products, transplant shock is reduced, resulting in bigger, healthier, and earlier vegetable crops. Jiffy Peat Pots and Jiffy Strips are biodegradable and OMRI approved for organic production.
