I'm in W. WA State. I plant tomato seeds in Jiffy peat pellets about March 15 and grow them inside for about two months. I grow twice as many seedlings as I truly want. I plant 1/2 them outside about May 15. If they die from cold, I still have the second 1/2 inside; in any case, I plant the second 1/2 outside about June 1 or so. I have had good luck with the early girl variety.
My forecast has changed again and the only night below freezing is what you said. Mine says Wednesday night 28 degrees and all the rest of the nights now are above freezing. Who knows what the forecast will say by Tuesday.

You do what JRandomFreeper, Johnny, does, grow a bunch more seedlings than he needs in case some die for whatever reason. I have trouble thinking about doing that as I can’t stand to think of dumping the extra seedlings that are alive. I have to get over that and grow more seedlings than I need. I’m new to growing this year so I need to do what you guys do.
