I transplanted my sown from seed tomatoes in solo cups. Now, roots started hiting the cup walls. Will roots be damaged by sun, do I need to protect them from sun exposure?

Like Worth said. I wondered about it for the longest time. Still managed to grow big and health plants.
There's an advantage to clear cups in this case, very easy to see when/how much a plant is getting root bound. |

no problems for me in the past.
if sun exposure were to damage the roots, then i would imagine the sun could damage the plant due to perhaps too much sun too soon if they aren't gradually hardened off. i use cups with a wider bottom. they provide more stability when the plants get larger, and are more prone to falling over. trade off is less plants per tray. keith |

Interesting, I have only ever used the Red Solo cups. Might be fun to use a few clear this year and see if there is any difference in root growth or top growth. They look like nice healthy roots.

I cut holes in a bunch of glass mason jars and grew tomato sets in them.

I have found that the seedlings actually grow better in the clear cups over the red cups. I keep them under lights until ready for hardening off and keep them in a table tent during the hardening off to avoid direct sunlight. The root systems always seem stronger in the clear cups and I enjoy watching them grow. The other advantage is that you can see how moist they are all the way down.
