Replacement Planting Block for 8 Mega-cell Dome Seed Starting Kit

Your 8 Mega-cell Dome Seed Starting Kit is made for a lifetime of use, so keep it growing its best with this replacement planting block and sponge set. Containing 8 mega-cell sponges, and a replacement block that fits perfectly into the climate controlled seed starting environment of the 8 Mega-cell Dome Seed Starting Kit.

This amazing 8 Mega-cell Dome Seed Starting Kit takes all the marvels of the Bio Dome design and magnifies them into a size suitable for rooted cuttings, half-grown plants, plant divisions, and more. It not only starts seeds and grows big, healthy seedlings, also root cuttings.

The 8 Mega-cell Dome Seed Starting Kit is a humidity controlled, bottom-watering tray along the same principle as our classic Bio Dome. The cells here measure 3 inches in height and 2¾ inches in diameter at the top (their widest point). They are made of the same premium bio sponge material as the original Bio Dome, thus providing optimal aeration for the roots.

The material and the shape of the cells encourage the roots to grown downwards rather than spiraling or remaining near the surface. By the time they leave the Mega Dome, your plants are in great shape for transplant into their permanent container or the garden.

This pre-formed Replacement Planting Block can be washed and re-used almost endlessly. It fits into a deep plastic tray, with room at the base for water and seedling food. The tray fits neatly below a clear plastic humidity dome that features a circular, adjustable vent for premium climate control. Everything is in place for the best seed starting and growing on experience of your gardening career.
