New! Star HortiBlock Germination Tray

Over the years, we've planted and experimented with more than our fair share of various mini-greenhouses and seedling starter kits. This is the one model we all agreed is a winner; in fact, it's the same product that's been used by professionals for decades. All you'll need to add is the growing medium (and the WonderSoil pellets, #WSSWP are ideal!).

Several unique features make this kit a winner:

• High-tech styrofoam tray is designed with a smooth, high-density surface that does not allow roots to penetrate; that makes seedling removal stress-free for you AND the seedlings! Plus, the cavities are engineered for vigorous downward root movement.
• The tray floats on water for even hydration for the seedlings. Unlike trays that use capillary action, the Pro Hot House enables optimal water intake by the seedlings, and there is NO matting of roots to any surface! This floating technology has been proven successful by the commercial industry for over 30 years!
• The SmartFit lid snugly fits into the bottom tray to conserve any condensation. Any moisture that collects on the lid simply trickles back into the water reservoir instead of making a mess on the shelf.
• The vented tray provides an ideal air-to-water ratio. Small holes enable appropriate air transfer to ensure proper humidity, and minimize likelihood of damping off and fungal diseases. Plus, if you use the Wonder Soil pellets (page 3), you'll be planting in a soilless medium free of soilborne diseases and fungus gnats!

This is not a cheap disposable system; you'll use this hothouse year after year to grow healthy seedlings for your garden. Each tray has room for 40 seedlings. Ship wt. 2.5 lb.
