Anyway, the heating mats being reviewed here are a very functional product. Your success rate in growing healthy and ready to transplant plant will much greater by using these things. Now there are a couple of things to note before you get started using these things.
First, you should have a good thermometer on hand to regulate the heat of your plants. They make specialized one just for this purpose but to be honest with you, I have a digital one specifically designed to test the heat of meat while it is on the grill and it doubles in duty with my seedlings. I check on them periodically using this device. I would strongly urge you though to purchase a temperature control thingy especially designed for heat control in these mats...it will lessen your "fret" time. These mats are relatively safe to use and are unlikely to boil your plants but you can never be too careful.
Secondly, you need a very, very good source of light! I personally use very cheap banks of florescent lights on mine to supplement the weak light we receive through our windows.Read more ›

Be careful not to let your seedlings dry out
Works great so far made ghost peppers and others sprout which requires 80-90° F. You also need digital controller for precise heat setting .Published on April 25, 2014 by pat s sr

The only problem i have with this mat is that it heats it up too much. Read more
