| 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. |
