Bio Dome, meet Mega Dome! This amazing 8-cell 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!
Now you can grow big, healthy seedlings indoors, no matter how long spring is delayed or transplant is postponed. Not only can you root cuttings, you can also get your well-branched, full-grown new plants underway without transplanting to a bigger pot size. And you can grow houseplants all the year round without the need for repotting!
A humidity controlled, bottom-watering tray along the same principle as our classic Bio Dome, the 8 Mega-cell Dome is ideal for germinating seeds and growing on big, healthy plants. These cells measure a HUGE 3 inches high and 2¾ inches in diameter at their widest point! They use the same premium bio sponge material to provide optimal aeration to 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!
The cells are set into a pre-formed planting block that can be washed and re-used almost endlessly. This, in turn, is placed 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!
The base tray measures 14¼ inches long by 8 7/8 inches wide by 2¾ inches high. The humidity dome measures 14 7/8 inches long by 9¾ inches wide by 5¼ inches high. Compact and perfect to place on heat mats and below grow lights! Refills available.
