      I started tomato seeds in January and with this heat mat they have taken off. I would highly recommend this product.

      I bought this mat, the grow light and the temp controller. This has been great at starting my seedings. It only made sense to keep the soil and baby roots warm along with the grow light. My tomatoes are growing great now outside. I would recommend it.

      For consistent tempeartures, use this with the Charley's Greenhouse Hydro seeding system and a thermostat.

    • Easy to use

      Having never used one before I don't have past experience but believe this one is easy, directions were fairly easy to understand and use has produced good results. I believe it has helped using it in conjunction with my grow light system. I am already seeing baby tomato plants. Makes sense to keep soil warm too. Also bought the thermastat regulator.
