Riogoo Starter Seed Heating Mat 10x20.75 Inch 17W Plant Temperature Control

These are a set temp and don't use too much energy, but my seeds seem to love them! I purchased these and put them under self watering germinating trays. Not even three full days later and my cucumbers and cantaloupes are already sprouting. While temperature isn't adjustable, they are really affordable and do the job quite nicely. They fit a starting trey with 60 spots nicely with a tiny bit of overhang.

These keep a steady temp and work great. The arrived in a day and got put straight to use! The cord is a bit short but we made it work. just know you might need to have a power strip or something to reach your plug in.

Right out of the box it worked like it was described. Perfect size (3) smaller seed trays and maintained a consistent temperature throughout the seeding germination.

These plant heaters work well. I do wish though, that I'd paid a bit more for ones with a built in thermostat. Not sure that there would ever be a reason to change the temp. but it would have been a better choice in case this seed starting is becomes more than a phase.

I love these. this is my second set. my old set of Riogoo heat mats are about 10 years ols and are still going strong. they are the perfect size to fit under the seed flats. I just plug them in and forget about it beings that they have a built in thermost. I can count on the temperature staying just right for my baby plants. Thank you Riogoo for making seed mats that can be counted on.

The product is as advertised. It works well and helped my seeds germinate considerably better than without.

Works really great helps seeds to germinate faster especially green peppers

I have only been using this product for a few days, but it heats up as expected. The size is perfect for my containers.

Works as it should. I am using it for my seedlings. i wish it had temperature control but for the price I think it was a fair deal.

these mats once plugged in go to 120 degrees and it killed all my seedlings smh
