This McKenzie with Jiffy Tomato Greenhouse is your plants' ticket to a thriving garden. The large 50mm peat pellets provide the ideal starter home for tomato seeds and other plants like herbs and peppers, allowing roots to develop before transplanting outdoors. Simply place the tomato seeds in the pellet, set it in the waterproof tray and cover with the clear dome to maintain humidity as the seed germinates. In about two weeks, lift the dome to harden off the plant before planting in your garden bed. The result? Healthy tomato seedlings with robust root systems ready to take on your garden and produce an abundance of juicy tomatoes and herbs all season long.
