Instruction - When it's time for transplanting all you do is push up the base and seedlings will slide out the seed trays. Note that you should firstly water and lightly tap the plant trays, the whole thing comes out like a cube, nice and compact with very little if any breakage or spillage of the medium.
Detachable Base - The base is designed to be detachable and on the inside of the seed starter tray, works amazingly to eject roots smoothly out. It's the only way to safely, basically risk free, to get the plant out of its seedling home. No squeezing trays makes they become truly reusable!
Ejector Seedling Tray VS Traditional Transplant - Traditionally transplanting will squeeze the seedling starter trays and spill out their contents, in which medium goes everywhere exposing the tender roots, and high risk causing a shock to the plants system. But with "ejection method", you just push the base from the bottom and out comes everything painlessly and safely.
Ideal Germination Trays- Gardzen seed starting kit includes 12-cell insert trays, base trays and humidity domes. The insert trays with drain holes at each bottom prevent overwatering, the base trays is ideal for use when propagating to catch the excess water that drains from seed trays. With humidity dome, you can adjust the ventilation holes to control humidity and temperature.
Perfect Size for Seed Starting - The tray insert provides 1.5" square inches of growing room per cell. The tray inserts are 2¼" deep to allow the plants have deep roots. Transparent cell is ideal for observing root growth.
