We managed to take the plastic off of the high tunnel in time for holiday break. The tunnel has been covered since 2010, so it is definitely time for new plastic. We took a soil sample today in order to compare it to the soil sample taken in 2010 in order to see if there has been a buildup of salts. Soluble salts may build up in a high tunnel since it is covered and rain does not wash salts out. By taking the plastic off and waiting a while before we replace it, we hope that rain will allow any salt buildup to wash away.
