I have done this several times in the past and decided to try it this year! I plan to start the seeds under lights then after they emerge in a few days put them into my solar greenhouse to get more light! The 59 degree temp allows them to come up in a few days while in my greenhouse it takes over 10 to 14 days because of the below 40 night temp!
I welcome any tips on this way of starting seeds. My own tips get a remote acurite temp meter $9 Wal Mart and put the remote near the starter boxes and check the temp all the time right in your kitchen without going down stairs! What I noticed with this set up was when I surrounded the boxes with insulation the 59 degree basement temp went up 3 degrees. You can also see the change in temp as you move the lights closer. I placed white styrofoam around the boxes not only to insulate but to reflect light from the lights back to the plants for more intense light!
Another thing to do with the remote is to place it in different places in your greenhouse to see what temp that area will get. I also put a remote in my greenhouse which is 100 feet from the house and can read the greenhouse temp from the house since the remote woks up to 160 feet away! I like to see how the greenhouse temp reacts to the outside temps even at midnight or how much the greenhouse temp drops the first hour after dark. Lots of fun!.
