Park's Original Bio Dome Seed Starter revolutionized indoor seed-starting. Now we're proud to introduce the DOUBLE version of this mini-greenhouse, which grows up to 120 big, healthy seedlings!

When we say that this seed-starting system from Europe is revolutionary, we really mean it! Now you can start your favorite vegetables and flowers indoors, for earlier crops at a fraction of the cost of buying plants. And you can select the varieties YOU want (not the half-dozen choices the local garden center picked out), confident that with Park's Double Bio Dome, your seeds will sprout and your sprouts will transplant easily into the garden!

This little powerhouse from Holland bears almost no resemblance to other seed kits, which tend to produce spindly sprouts with curled-up roots and limp stems. Park's Double Bio Dome seedlings grow to a uniform height and width, thanks to the spacious distance between each growing cell. And our growing medium -- the Bio Sponge -- encourages root growth downward, NOT in an upward spiral that eventually strangles the plant! With the Bio Dome, you place only one seed in each Bio Sponge, which really helps stretch out today's smaller seed-count packets. The only seeds unsuitable for the Bio Dome are very large ones (which you would want to direct-sow, anyway) and root vegetables needing space to grow their tuber, such as carrots, beets, and radishes.

Before and after germination, your seeds receive just as much light, water, heat, and air circulation as they need, thanks to the adjustable vents and bottom-tray watering design of the Double Bio Dome. This environment offers such great growth conditions to the emerging seedlings that Bio Dome plants are usually ready to transplant a bit quicker than other seedlings -- and they suffer virtually no transplant shock in the garden.

Here's what you get with Park's Double Bio Dome Seed Starter system: 1 double sized black bottom tray, 1 clear plastic vented cover, 2 60-cell planting blocks, 120 Bio Sponges, and a free packet of seedling food. The double base measures 20 1/2" long x 16 1/2" wide x 3 1/2" high, while the clear top measures 20 1/2" long x 16 1/2" wide x 6" high. Original planting cells are 1" wide x 2 1/4" deep.
