Maximize your germination area!
Plugs into Master Heat Mat or another Modular Add-on Mat. Proper bottom heat is one of the most important and effective ways to improve germination. This new modular system lets you daisy chain mats together to cover more area, and provide uniform heat for hundreds of seedlings or cuttings. Supersized mats are rugged, durable, and are fitted with waterproof connectors. Up to 5 units may be connected (4 Add-on Mats plus the Commercial Mat). These mats must be used with a temperature controller; failure to do so will result in excessive root zone temperatures. We recommend #9582 Heat Mat Controller (will accept up to 4 total mats).
