actually, there are some things that you should do when you start seeds indoors. i am talking striclty vegetable seeds as i never grow flowers from seeds.
heat - like i said before. toamtoes do not need bottom heat but if you do it, it won't harm them. (when i fist started growing seeds i used a heating blanket which i got for our wedding and never used) to heat my seeds. did that for maybe 10 years without a proboem. then someone told me on DG that i might be taking a chabnge with something that old so i stopped using it.
i didn't want to buy heat mats so i took a nice warm blanket put it on the floor of my living room, put the seed tray on top and then the dome or plastic wrap to cover the seeds and then another blanket on top. never had a problem with either method.
light - vegetable seeds need 16 or 17 hours of light a day. sitting them on a window sill will not be enough light. even a sun room is not enough.
after the plants get their second set of leaves, then it's time to place them in a cooler location. vegetable plants germnate best at about 75 to 80 degrees (some hot peppers need 90 degress and thats where heat mats come in) but after that the plants grow best at 60 degrees except for the peppers and eggplants.
i used to take my tomatoes etc and put them into my unheated basement with grow lights over them until it was time to harden them off.
now that i have my mini greenhouse in my computer room i don't have that trouble because now when the plants need the cooler temps i can just open a window a bit.
a fan - it is always good to have a fan lightly blowing on your plants after they get there second set of leaves. it stimulates grown and makes the stems stronger. you can also shake them wiith your hands for the same effect. the fan only hasto stay on a few mnutes each day.
sorry about rambling on and i know everyone hast heir own method to start seeds and there sure is more than a dozen different way to do it but that is how i do it.
