    You might look closely at each sheet and see if there are any markings or sealant on the edges that would tell you they had been to the outside. Another way, but a real time consumer, is to place the panels against something like a sawhorse, lay newspaper underneath them for a while and take note of the ones where the news paper starts to yellow first, this may help but is not fool proof. You might try contacting the folks at this link and see if they have a good way to determine this, I know it is very important: http://www.greenhouses-etc.net/glazing/contact_us.html

    I think the first choice is better. Clear plastic may actually let too much light in and may heat up the area too much, killing the plants inside the hoop houses.

    Most seedlings like a humidity level of 50 to 70 percent. Higher humidity levels and poor air circulation can lead to fungal issues and other disease problems. If your greenhouse is too humid, you may want to consider running a small fan to help circulate the air.
