It's safer to do that. But Solarizing is super easy. Just take off the plastic cover, and wrap the whole thing in a well sealed heavy duty CLEAR plastic bag. Barb_FL, our resident scientific trailer, experimented with temps on clear vs black plastic solarization, the clear got about 20 degrees hotter. Clear let's the light through, black absorbs it. Classic greenhouse effect.
