    QUESTIONS & ANSWERS

    Ask a Question
    • I purchased one of these kits over the winter and am getting ready to try growing annuals from seeds for the first time. While researching, I've seen some systems use a flat sponge-like sheet for holding water. Is this necessary? Also, what is the recommended level to fill the water? Thanks!

      Rockwool cubes?  You can certainly use those.  They work very well, especially for beginners.  Alternatively, you can use you a soil or potting mix to start your seeds.   Best to put a 1/2" of water on the bottom and use the dome to retain the humidity.   Without the dome, you can also fill the bottom tray with water just so it touches the bottom cells, wicking up the water.  In order to avoid over saturation, a little air blowing in the room is using good propagation practice.   If you want to avoid using the dome at any point and also want to avoid lots of water, just be sure to mist your seedlings a few times a day.  Hope this helps!

    • Can I use a heat pad under this? I'm starting seeds in a fully-enclosed, but unheated utility room. Typically I only see heat pads underneath trays that don't utilize a water bed underneath - so I don't want to heat just the water and encourage mold growth around the roots. Maybe I should just use a grow light instead? (asked on Amazon, too - sorry to duplicate!)

      Yes you can absolutely use a heat pad under these trays even with a water bed.  We do this exact same thing when we grow our seedlings with great success.

    50 Cell Seed Starter

    Using this system has made my seed starting so much more efficient than using the flimsy starter sets from big box stores. I will be adding to collection in the future.

    EXCELLENT SEED STARTER KIT

    I am delighted with my purchase. Well constructed and will last many years. Reasonably priced. Only thing that could improve it would be to have a wicking system or an alternate thought which will probably be unpopular with some, is to make the bottom tray transparent so I can see at a glance whether the soil is wet or not instead of having to take an educated guess. My big error is always overwatering. But I love, love, love this set.
