Oasis® Origins Seed & Clone Double Box makes growing easy. These refill sheets are compatible with standard growing trays such as in the Speed Starter Kit. The Seed & Clone media features a star-dibble for use with clones and the option to simply increase the hole size if using seeds. The convenient packaging allows you to use what you need and store the rest for the next crop. Not only that, the consistent media structure of Oasis® Origins offers the ultimate air to water ratio that young plants need to thrive.
