I have recently planted many siberian tomatoes from my own seed. I have started them in a mini hot house(clear plastic storage container). All the children are looking good and are about 3" tall. The problem is when I take the top off and let them out into the world 70 deg and sunny they wilt and look like they will die in 15-20 mins. I then put the roof back on and within the 15-20 time frame they are all better.
It apears they are scared of the sun.
My babies need help.
