Your Bio Planting Block will last a lifetime with these handy, economical Bio Sponges! When you're ready to begin a new crop in the Planting Block, first be sure that the block has been thoroughly disinfected (warm water with a splash of bleach is fine). Then soak the Bio Sponges you intend to use in warm water for a few minutes. They expand, revealing the pre-drilled planting hole at one end. Simply slip one seed into the hole of each Bio Sponge, place the Sponge seed-side-up in the cell of the Planting Block, and you're on your way to another bumper crop of healthy, strong, super-quick seedlings!

Bio Sponges are now enriched with oilseed extract, giving your seedlings an extra boost of nutrition. You'll love the results!

3 different sizes available for replacement in the Original 60-Cell (sold in packs of 120), Jumbo 40-Cell (sold in packs of 80), and Whopper 18-Cell (sold in packs of 36) Bio Domes. Replacement Planting Blocks also available.

Bio Dome Success
Tim Gross from NE wrote on April 05, 2020

Planted 62 Park's Celebrity Hybrid tomato seeds in my brand new 80 cell Bio Dome and 56 germinated. Look very healthy. Growing fast. No mess and easy to plant using Bio sponges. Going to try some pepper seeds next.

Have worked great for years
KY square foot gardener from KY wrote on October 30, 2018

quick and convenient Very easy to replant in the beds. I have kept zinnias in this medium with open biodome for weeks while I waited to see how various flowers would thrive in the garden and then replace in the bed as some planted weak plants faultered. I clean the biodome with dilutedbleach at the end of season.

Very Good product

Great product and very easy to use. Seeds sprout and grow easily by following the simple instructions and providing the proper light.

Happy with Bio Dome Seed Starter

First time user of the Bio Domes and the growing of petunias. Very happy with results. I have had 85-90% success in Park Seed petunias. Germination in 4 days using grow light and heat mats. Yesterday started tomato and pepper seeds. I liked the no mess in the house and ease of watering. Will definitely be buying more to the five I already have.

Love the Bio Dome

Parks Bio Domes are great. Follow the instructions and you can not go wrong. Parks also has a great support line.
