Description / Bio Dome Planting Blocks with Sponges

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. We have even enriched the sponges with oilseed extract, which gives seedlings an extra bump of nutrition.

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 <#prodlink#"06529">Original 60-Cell, <#prodlink#"06456">Jumbo 40-Cell, and <#prodlink#"96064">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.

96601 60 cell block: L - 13¼", W - 8", H - 2¼"
96605 40 cell block: L - 13¼", W - 8¼", H - 2½"
09322 18 cell block: L - 13½", W - 6½", H - 3"

Review by Pamela Bloom
I bought the domes and inserts several years ago and have really enjoyed a variety of starts. the foam wedges are durable and easily transplantable. the polystyrene inserts also hold up to scrubbing after exposure. I have started plants for our aquariums in them and drop. works great. After 3 years I did buy a new insert, still waiting on the aftrican violets to sprout.
Kinda of pricey, but wow - they work
Review by Avatrix
Every year about yit his time I grumble around about the cost of these, and then wait fo a sale an d buy them. They are the best seed starting I have tried, and the 40 hole version seems to be the happy medium. I grow my zinnias, peppers, tomatoes and basil in them - the peppers and tomatoes get moved into pots as they get bigger. I wind up buying some of the foam inserts because the old ones get covered with algae if I keep the zinnias in them too long and they are hard to clean, and I run out of time. They transplant well too. And germination rates are high in these - better than other systems, plus they make it easy to control the watering. I just wish they were a little cheaper or the shipping was a little less.
Best and Sturdiest Seed Starting System
Review by K. Romer
I have tried many different seed starting systems over the years, but keep coming back to Parks. It's simple, and reliable. I always have excellent germination rates with this system, even with older seed. I don't mind that the blocks take a long time to break down in the garden. I feel this adds extra water retention for the soil to both deal with excess water and help in times of drought. Would definitely give it 5 stars, except that it is a bit expensive. However, even though I try to live a somewhat frugal life, I still justify the extra expense because of the excellent results. I don't like direct sowing unless I can readily identify a very young seedling, as living in a semi-rural area, we have so many weeds that self sow in the garden even with mulching, that I don't want to risk accidentally letting a weed (especially a poisonous one such as poke weed) grow. Also, many other seed starting systems are very flimsy, but this is nice and sturdy. I have been using this system since it first started and still have some of my original blocks! One thing I do is to transplant when young and not put the blocks in the sun. That way I'm not using these containers when hardening off. Another tip, I use the blunt end of a chop stick to push the cells from the bottom when removing to prevent damage to the plant and the starter block. Base and dome are also very sturdy and have survived my hubby's rough handling (tossing here and there if he's looking for something on my work bench #!$#!). BTW, I also love the way Parks packages their seeds - keeps them viable for a long time.
These are great
Review by Delia
I have several different sizes. I grow stocky tomato pepper and eggplant seedlings in the 40 sponge and cabbage, broccoli etc in the 60 sponge. With these sponges on the Styrofoam blocks if you will be gone for a few days you can put quite a bit of water in the tray and the block floats so the plants do not drown or get too wet and suffer damping off disease. I have a shelf with a heat mat under and 2 fluorescent shop lights over in my garage,
love it love it
