Drop Off
Barton Hall is open to the public daily from 8 a.m. - 5 p.m. Monday-Friday. Follow the signs & head upstairs to Barton 206. You may leave your plant sample with a form with anyone in the lab OR leave it in the blue sample drop off boxes outside of the lab door.
Do not drop off plant samples in the soil drop off box outside of Barton Hall. We are unable to process plants samples from that box because they degrade too quickly.
