I have several tomato seedlings that are now getting too tall for my light set up. They've been repotted once into 16 oz solo cups, and while I was gone last week seem to have doubled in size! I have a greenhouse, but its not fully heated - temp right now is ~65 -70F. Would that be too cool for the tomatoes - I'm thinking they would slow down growth a bit - which is fine, since I still have about a month (or longer given this yucky spring) before they can go out. Thoughts?

It is too cold in zones 5-7. The controlling factor is the nighttime temperature. It needs to be at least 45 degress; 55 degrees is better. If you decide to set them out anyway, use a pot, can, or other cover to protect them during the nights and any cold days. May 15 or later is better for your zone.

They should be fine in the greenhouse. They should actually thrive as long as the nighttime temps don't get too cold.

I'm getting ready to put my tomatoes out in a sometimes heated coldframe in a few days.
