Park's Double Bio Dome Tray

The ideal reservoir for your seed-starting flats

Item # 96996
Instock - allow 3-5 business days for processing prior to shipment.

Whether you need a new base for your Double Bio Dome or simply want an all-purpose, ultra-sturdy tray to house your seed-starting pots and flats, Park's Double Bio Dome Tray is the answer. This very heavy-duty plastic tray has steep sides, a wide top lip to accommodate a dome or plastic wrap, and a watertight base to serve as a reservoir for water and liquid fertilizer. It's just what you need to keep your seedlings healthy and growing their best.

Measuring 20½ inches long, 16½ inches wide, and 3½ inches high, the Double Bio Dome Tray is the ideal size to hold 2 Bio Dome planting blocks—either the 60-cell, the 40, or the 18. (Regardless of the number of sponges in each block, the overall size of the block is the same.) It's also just right for several medium or small Perma-Nest trays and for numerous square and/or round Jiffy Pots. And it's the perfect place for all your Park's One-Steps (Jiffy-7s).

And its usefulness extends beyond seed-starting and seedling growth. This bottom tray serves as a great place to set annual plants that arrive in Elle Pots or plugs with drainage holes in the base. Set them into the tray, water them well, and let them acclimatize (harden off) in a shady place in your garden. They will be ready to transplant in a day or two, thoroughly watered, rested, and re-energized.

During the winter, this sturdy tray makes a good home for potted plants that you bring indoors. Simply remove their saucers and set them into the tray, then water and feed the entire tray at once. A handy size to set beneath plant grow lights, too.

Keep your seedlings and plants well-watered, fed, and sturdily supported with Park's Double Bio Dome Tray. Pick up a few spares today.

Great tray.

I think this is the best tray I've used. I had been using metal and they rusted so I have replaced all of the metal trays.
