Hi all. I start my seeds in a 2 1/4" peat pot. It's alot easier to heat up than a 4''. I put the 2 1/4'' peat pots in a plastic seed starting tray with a cover. I then put the tray on a heating mat. I am able to maintain 85 degrees very easy. In four day's they will germinate i then drop the small pot into the big one. I will scare the sides of the small pot with a razor and soak it in water before i put it in the bigger pot. This helps to break the pot down faster so the roots won't get bound. Works for me. Good Luck All Ethan
