40-cell Jumbo Planting Block

Park's Original 60-cell Bio Dome Seed Starter revolutionized indoor seed-starting, and the 40-cell Dome, with wider and deeper bio-sponges and more space between seedlings, enabled gardeners to start larger seeds and grow seedlings out more fully before transplanting them. Now we're offering just the 40-cell planting block and bio-sponges, which you can put into the same Bio Dome you use for your 60-cell planting block.

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 your seeds will sprout and your sprouts will transplant easily into the garden!

Seedlings in Park's Bio Dome with 40 Jumbo Cells 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! 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.
