Simply the best seed-starting system in the world!
The revolutionary seed-starting system that has transformed the way we start seeds! 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 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 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! 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 Park's 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. These Planting Blocks arrive complete with Bio Sponges, which need only to be immersed in lukewarm water for a few minutes to be ready for planting. Sowing seeds doesn't get any easier than this!

3 different sizes available for replacement in the Original 60-Cell, Jumbo 40-Cell, and Whopper 18-Cell Bio Domes. The blocks are inter-changeable, so if you want to expand your planting capability, it's the perfect add-on!

If your Planting Block is still in good condition, refill Bio Sponges are also available.
