I was looking on Amazon for heating pads for seed starting. Before I buy one I was wondering if any growers have a preference for any certain ones on the market. Any advice would be helpful and appreciated.

I've used hydrofarm seedling mats for many years. I do not place pots or seedling trays directly on the mat. I place 3/4 spacers every 4 inches and place the trays and pots on them.

I've been using this temperature controller on my heating mats the last couple years and it's worked pretty well.

I tried a heating mat and a humidity dome last year but got terrible results. I'm not sure exactly where I failed, but none of the seeds I planted grew, I ended up planting outside, also with terrible results. This year I'm running some tests with a 27 gallon rubbermaid tub, a fish tank thermometer and some floating seed trays. So far I'm 10 for 10 and they are shooting out of the soil in 72 hours! The water stays at a constant 90 degrees and it heats the soil up to 86 degrees. Plenty of humidity so the soil stays moist without watering, but never gets wet.

Last year I used a wireless thermometer with a soil probe, I put the probe in one of the planting cells, I had no seeds in that cell but I kept it watered just like I did for the ones that were.

easy way to check on the current temp

I use an incubator. It works great and very controlled temps.

The oven with the oven light on works excellent 88 degrees. This is where I proof my sourdough bread...as long as you make sure everyone is aware there are seeds germinating in there

I use Christmas lights under my seeds. Be sure to check the temp of the soil, then adjust height.

I use the standard heating pad for muscle aches,on low setting.Wrap my peat pots in plastic wrap so no drying out(looser at top).Cover with towel for even temps.Stick a glass thermometer(thin)in the soil regularly to check temperature.
