Park's Original 60-cell Bio Dome Seed Starter has revolutionized indoor seed-starting. This 40-cell version of the Bio Dome is quickly becoming even more popular, with its slightly larger bio sponges for bigger seedlings than ever!

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 Bio Dome with 40 Jumbo Cells, 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. The 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!

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 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. You're going to fall in love with this system, and your garden will thank you for it!

Not consistent
Anon from NC wrote on April 14, 2016

I had varied results with the biodomes, and am not sure why. Initially, I thought that the germination was a really high percentage, but on subsequent starts, it was not, some with as little as 10% only. I think the product is a great idea, but I am not sure it is consistently better than other methods.

Bio Dome

I had my doubts when I purchased a 40 cell Bio Dome last month. I had my neighbors 7 and 11 year old kids help me get veggies started for this years garden. I skeptically told them just one seed per pod. In two days a dozen sprouts were up. After a week everything except peppers and eggplants are up with 100% germination! We are so pleased with this product we will be looking to buy another next spring! Thank you Park Seed!!!

Thrilled with Biodom

Bought this Biodom and planted my Park Seed Geraniums, (which are the best) and in a weeks time the seeds have already sprouted. This dom works wonders; its effortless. I am thinking of purchasing another one. LOVE IT!

Amazing results!!

Last year I started my seeds in a regular plastic tray with MiracleGro potting soil, thinking it was a good brand (the sad lessons of a beginner!). The result was leggy seedlings which succumbed to damping off within two weeks. I hesitated before I bought these but it has been worth EVERY penny. The seeds have superb germination and the seed dome provides the perfect atmosphere! Highly recommended if you start your own flowers.

Unused but well packed

I haven't used them yet, will in a couple months. I ordered 4, two 40 cell and two 18 cell. The domes and bases look and feel very durable and should last for years. The domes and bases are all the same the difference is the size of the 'Plugblock' (noted on the side of it) The packing was also excellent. I buy a lot of stuff online, a lot a lot. Each was packed in its own box of THICK cardboard box. On the inside of that a few inches of Styrofoam packing peanuts. On the inside of that the domes themselves wrapped in a layer of 3/4" bubble wrap. I can honestly say I have never seem a more well packaged product. I expect the performance to be just as good as the packaging and as previous seed rates. But I'll post a review in time.

What are the differences between the various Bio Domes: 60-cell, 40-cell, and 18-cell?
Bio domeThe original 60-cell Bio Dome has a 60-cell planting block with 60 Bio Sponges and will produce 60 plants at one time. The 1" wide by 2 ¼" deep cells are larger than average, and a spacious 1 3/8" apart. The bio-sponges are the same size as the cells; 1" wide by 2 1/4" deep. You can grow and keep plants in the 60-cell bio-dome for 6-8 weeks before transplanting. Many varieties will just need 6 weeks until transplanting. Tomatoes and peppers would appreciate the full 8 weeks before transplanting. So, the original 60-cell bio-dome would be great for starting all of your favorite vegetable and flower seeds, with a larger number of plants produced at one time.

The 40-cell Bio Dome has a 40-cell jumbo planting block with 40 Bio Sponges and will produce 40 plants at one time. The cells are wider and deeper than the original 60-cell planting block and provide good spacing to maximize air flow. The cells are 1 1/4" wide by 2 1/2" deep. The Bio Sponges are also 1 1/4" wide by 2 1/2" deep. You can grow and keep plants in the 40-cell bio-dome for at least 6-8 weeks and some for up to 9-10 weeks, because of the wider spacing and cell/sponge size. It too would be excellent for starting all your favorite vegetable and flower seeds, with the added benefit of giving more room and time for larger plant development.

The 18-cell Bio Dome has an 18-cell whopper planting block with 18 Bio Sponges and will produce 18 plants at one time. It has the largest cells of any of the Bio Domes we offer and is great for growing extra-stocky transplants and even for rooting cuttings. The cells are 3" tall by 1 3/4" wide. The Bio Sponges are also 3" tall by 1 3/4" wide. You can grow and keep plants in the 18-cell Bio Dome for at least 8-10 weeks and some for up to 12 weeks, giving the maximum amount of growing time and spacing between plants as compared to the 60-cell and 40-cell Bio Domes. If you are looking to grow your favorite vegetable and flower seeds into large, stocky transplants for setting out in spring, then the 18-cell Bio Dome is the one you want to buy. It would be excellent for growing Tomatoes and Peppers.

How much water should be put in the Bio Dome and how often?
SeedlingsThe beauty of the Bio Dome is that you cannot overwater! You just keep water in the tray and float the block. The larger the seedlings get, the more water they will use and you will need to add water more frequently as they grow. Initially, during germination, you may not have to water as frequently, because minimal water is being used and Bio Sponges will stay moist longer, so you may only have to water once every 1-2 weeks. Later, as plants grow and water use is greater, depending on the room temperature and the amount of light received, you may have to water more often -- possibly 1-2 times a week -- or as often as required to keep the sponges moist.

Bio Dome Instructions


Remove the Bio Dome Styrofoam blocks from the plastic wrap, keeping upright so that the plugs do not fall out. The plugs are ready to sow as they are!

For most seed types, place seeds into the pre-dibbled hole at the top of each plug. Tiny seeds that need light to germinate should be sown on the surface of the plug, not in the hole. Seeds do not need covering in the Bio Dome plugs. Each plug provides the optimum environment for germination.

Place the germination units in a favorable location as indicated on the seed packet.

To moisten the plugs it is best to soak them from the bottom. This can easily be done by putting water into the under trays provided and floating the Styrofoam blocks. It is not possible to over-water by this method.

Place the dome on the Bio Dome to maintain the humidity around the planted plugs. Keep moist until the seedlings emerge. Because of their composition, the plugs retain just the right amount of water. Less frequent watering may be needed and there is no danger of overwatering as with some other germination methods.


When you see that germination has started, open the vents on the Bio Dome. After the seedlings have emerged, remove the dome and provide more light. Use a grow light kept 1”-3” above the plants as they grow. This will prevent the seedlings from stretching and producing a weak plant. Brighter light will help keep the seedlings short and stout. Water as often as needed to keep the plugs moist.


style=

Once the seedlings have developed their first set of true leaves, mix a weak fertilizer solution, following directions on the free fertilizer packet included with your Park's Bio Dome Seed Starter shipment. Water with this solution, instead of plain water; until the next set of true leaves develop. You can increase the concentration of the fertilizer solution once the second set of true leaves develop.

When the second true leaves appear the seedlings are strong enough to be transplanted. Transplant your seedlings, plug and all. To remove the plug from the block, poke out from the bottom and plant them where the plants are to grow.

If weather or timing delays your transplanting, often the roots will emerge from the bottom of the plugs. Prop up the blocks to allow some air space beneath them, until you are able to transplant but don't allow the plugs to dry. This builds a stronger root system within the plug.
