Grid setting in Marketplace has appearance challanges

Hi folks,

When I set the products display to the grid settings, it seems it all gets squished together. the image and description are fine, but they overlap the 'see more', the price, and then the buy now button. is there a code I can stick in somewhere to keep the allotted space for description constant so that no "step on's" happen. I can adjust the length of the description but still have the issue.

at present I am running the site in list format to avoid this issue.
as always thank you!

Chris
