Burpee SuperSeed Seed Starting Tray | 36 Cell Reusable Seed Starter Tray | for Starting Vegetable, Flower & Herb Seeds | Indoor Grow Kit for Plant Seedlings | for Germination Success

They are the easiest to use.

The Burpee SuperSeed Windowsill Seed Starting Tray | 8 XL Cell exceeded my expectations and made starting seeds indoors incredibly easy. The extra-large cells provide plenty of room for seedlings to develop strong roots before transplanting, which really helps plants grow healthier and faster. I especially love the thoughtful design — it fits perfectly on a windowsill without taking up too much space, and the drainage system keeps the soil moist without becoming waterlogged. The tray feels sturdy and reusable, unlike cheaper seed starters that crack after one season. Germination rates noticeably improved after switching to this tray because the seedlings had better airflow and consistent moisture. It’s perfect for herbs, vegetables, and flowers alike. Whether you’re a beginner gardener or someone who starts seeds every season, this tray makes the process simple, clean, and efficient. Overall, this is a high-quality seed starting system that delivers excellent results. I would absolutely buy it again and highly recommend it to anyone looking to grow strong, healthy seedlings at home.

We have been using them for several seasons now and absolutely loved them. They are so easy to use easy to clean and very durable.. by watering the bottom tray it’s easy to make sure that all your plans are consistently hydrated and well drained. We have two different sizes for different types of plants and reuse days for all the starters that we do at our big garden. The size is perfect and absolutely worth the money.. now that we have about six of them we are prepared for every upcoming planting season

These are my go-to seed starting trays after having used many others over the years. I like the silicone pop-out feature, the manageable size, the sturdiness of the tray, and the overall “look” of the trays . Since I own several of each size (orange, green, turquoise), I like the versatility (2 orange 8-cell trays can fit in the black bottom of a 16 or 36.) I agree with others that a humidity dome would be nice, but I’d rather keep the price affordable. (A tip is to cut apart clear plastic bakery containers and use these as humidity domes. Another suggestion is to use a capillary mat inside the black tray. (Mine are from Gardeners' Supply, available on Amazon). I cut them to size and then make sure this mat is always moist. This allows plants to water from below. (I live in a hot, dry climate and find capillary mats essential to prevent drying out.) My latest tweak is to use bubble wrap (the kind with the mini-size bubbles), cut to size, to lay directly over the newly planted seeds. It works fantastic to hold in heat and moisture, yet allow light in, until the seeds come up. I've had flower seeds that are supposed to germinate in 21-30 days come up in 3-5 days--yes!-- using this method [Hydrofarm-brand heat mat, Burpee black tray, capillary mat, Burpee tray inserts, moistened quality seed starter mix, mini bubble wrap, plant-growing light close to the trays]). I switch to my no-cost bakery-tray covers to use as humidity domes once the seedlings are about to touch the bubble wrap. I find that the inserts last about two years under frequent use (I’m continually growing veggies or flowers as an all-year gardener, so I’m popping out seedlings more than the average gardener.) I now have several extra black trays which I continue to use to hold two 6-packs of transplants (Ex: as tomatoes and peppers get larger, I put them in reused bedding plant 6-pack trays and water from the bottom using my capillary mats). This allows me to use my Burpee trays for new seeds or for dividing seedlings. (I'm continually "rotating" my plants to accommodate the space needed.)
