Perma-Nest Plant Trays and Humidity Domes

Sturdy, washable, and endlessly re-usable, Perma-Nest Trays are the mainstay of professional greenhouses, and now they are available to the home gardener. These trays can be used as seed flats, seedling growth trays, and containers for potted plants being grown under lights indoors. And they're perfect for growing microgreens. Match them with optional fitted humidity domes for even easier, more successful indoor growing.

The straight, high sides of these trays are ideal for filling with enough growth medium (such as Fafard's seed-starting mix) to allow seedlings to develop strong, healthy root systems before setting out. They also enable you to start larger seeds, those with taproots, and even small bulbs.

Best of all, Perma-Nest Trays never rot or rust. They resist cracking and breaking, standing up to cold weather and heavy soil-and-seedling loads beautifully. When it's time to store them, they wash clean in a trice and stack neatly to save space. The plastic allows tape to adhere, so you can label (and then easily remove) your plants. Growers have trusted Perma-Nest for decades, and we believe you will too.

Perma-Nest Trays are sold in multiples, and each tray has a corresponding humidity dome (sold in identical multiples, so you never have an unmatched part.) These clear plastic domes are the secret to increasing humidity and improving the germination and growth potential of your seeds. You may have placed plastic bags or wrap over seed flats in the past to achieve this, but the removable dome is much easier and more reliable. You can prop it open on one side to gradually reduce humidity levels, and the high arch enables you to use it even with tall, quick-growing seedlings. If your house is cool or you want to start seeds requiring high levels of humidity, be sure to get the domes to match your Perma-Nest Trays.
