Living in minnesota means a short growing season. I don't have an actual greenhouse, so I start ALL my plants in my house in a window. They do all right, but I am wondering what ideas you can give me for keeping them warmer so they are healthier. The average temp in late winter/early spring indoors is about 50F. Probably colder in the window, any ideas?
P.S. I read that you can put the seed flats in baggies to lock in water, and create a "Mini Greenhouse". What is your opinion? What do I do when the plants get to tall for the baggies? Thanks for the replies.

Maybe put them in something with plastic around it to keep them warmer. Wow I thought 62 is chilling for my house but 50 that is too chilly for me. I start mine in the windows too. I have some maters growing in my spare room and the temp is out 55 at night and they are growing good

I use heating pads under the flats to keep the em warm
Thanks for the help! 50 seems warm when its below 0 outside LOL!
It depends on the plants if you really want them warmer. Heat mats work (I think most unregulated ones will increase the temperature by 10 degrees or something in that range.) If you use it regularly, making a nice little greenhouse from glass and wood could be worth it. Grow lights do help to raise the temperature, too.
