Starting seedlings indoors during the cold weather is a great way to save money and provides a sign of hope that warm weather just may be on its way! The whole project, seeds + seed starting medium, cost about $10. I already had the desk lamps laying around, so I'm not counting the cost of those. Cost of energy is a factor, but I'm just blissfully ignoring that for now.
The key to this type of setup is lots of light and not too much water. Window light alone is not sufficient where I live, even though is looks bright outside. Too much water and you risk dampening off, a condition that causes yellowing and plant death. Also, seed starting medium, which is very fine soil with a little vermiculite, is key to seed growth. Potting soil may contain sticks and rocks and other things that don't give a seedling much of a chance of pushing through.
Try starting your own seeds indoors instead of shelling out cash at the nursery - saves money and is pretty fun!

































If you get tired of switching the lamps on and off, get a timer. About 18 hours of light would be optimal so just fill up the times of day when ther is not enough light.
This shoud help you keep your electricity bill low ;-)
Try to put glasses over the young plants as they like a humid enviroment.
Overall nice start ^^
Thanks for the contest!
