I'm going to do stand California Wonder Bell Peppers this year. This sin't my house so the garden isn't quite as big as I would make it. Waiting for the night time temps to get into the mid 40's at night to start them sine they will be in a grow box out on the back porch. Should be within two weeks. Let them go a few weeks then I'll start my tomatoes in same grow box. At least that's the plan so far. We'll see how it all works out this year.
I've done multiple sweet and bell pepper varieties myself and they're faster and more fun than the super-hots that I dually delve into. I do everything from seed and it's a pretty simple process. It's a good idea to pre-soak pepper seeds in a solution of water and hydrogen peroxide(two drops to 4oz water ratio, then rinse.), which alleviates any mold or PM sporulae that may be present on the seedshell itself. The top of my refrigerator is the perfect temperature for germinating seeds! I lay my germination bags up top the fridge and check them and ventilate them twice a day and it's pretty spot-on. Everything pops up there.
Then I fill up 4 inch starter containers with a 50/50 mix of Roots Organic(regular) to Cactus Mix and using a single chop stick(as in sushi chop sticks) I use a chop stick point-side-down to make a deep narrow hole in the medium within the container and then tail-side down I plant my seedlings just to where the seed shell itself is just below the surface. Make sure to gently push the surrounding medium in a way that helps encompass the seedling. Then I spray it with a water bottle to gently moisten(as opposed to watering and soaking the seed). I do this because there's this thing called "Helmet head" that happens when a seedling can't break free from the seedshell itself and aborts. It happens alot and I've just given you the formula for how to avoid it!
Be it under fluorescents or in a bay window, in a greenhouse, or you can make your own portable weather resistant starter house with the use of painters tarp, a few wood stakes and/or hardwear cloth or whatever it takes to make a frame that can be covered with transparent sheeting under open sky. Get creative! Anything goes.
There is a "hardening off" process that needs take place before you can openly plant your starters into open ground susceptible to wind, rain, heat, frost, inclement weather... and the starter house that I've just described are what I've used for aeons now to give my pepper plants a good head start.
Then again I am very blessed to have a favorable micro climate that accommodates long season annuals as well.
