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.
