Finally got pictures posted of how we do our seedlings - these growboxes are wonderful. Please go to http://community.webshots.com/user/homesteadernv and see the album called growboxes. These work so well for us, the best method we've ever tried. Humidity stays just right. Cats stay out!! - we turn the light on during the night, which keeps the seedlings warm and toasty during the colder winter nights, and turn it off during the day. We use four total - the living room is covered but it's so nice to have the little plants around. Once the cool season ones are out and in the ground, the warm season seeds go in. The white of the styrofoam helps to reflect the light inside the box. To water you do have to lift the light up and sit it on the ground (kind of a pain after a while) but oh well. You can do this with the light on by the way. Enjoy - if you have questions just post them here - I'll answer!!
