This is my first year growing tomatoes from seed, and I have followed all of the FAQ information, and have been hoping for success! I am growing costoluto genovese, ildi, reisetomate, black cherry and tie dye berkeley. My boyfriend has recently built me a greenhouse (which the picture shows only one shelf of tomatoes, there are more on the other shelf). The greenhouse is in direct sun almost all day. It was 25 degrees (~ 80 F) in the greenhouse when it was 9 degrees outside, and that was just in the early morning! Wow!

I am wondering, should I be worried about the tomatoes overheating in the next 2 weeks while they are out there? I can leave the door open, if overheating may be a problem, or put a tarp over it?

I will be bringing them in overnight if the temperature goes below 50 (F). I have also left 8 healthy plants downstairs under my lights, just because I am new to all of this and don't want to kill off all of my tomato babies.

Any suggestions or input would be greatly appreciated!!

:) Thanks!

A little heat stress as a hardening process would not be a bad thing (90F for a few hours). Just make sure they have plenty of water, some air movement and the heat doesn't last too long.

Warm humid conditions with little air flow could increase disease problems.

I have opened the door and the temperature isn't rising above 80. I will be sure to keep them watered and not let them stay out in the intense heat to long as the days get warmer!
