Word of Penn College’s hydroculture greenhouse, a collaborative initiative based at the Schneebeli Earth Science Center near Allenwood, is traveling throughout the United States. In addition to the college’s own coverage, a recent article by Williamsport Sun-Gazette reporter Joseph Stender was distributed nationally by The Associated Press. Barely a week after the story appeared locally, it has been published in San Francisco and Houston and picked up by newspaper chains in Connecticut, Delaware and New Jersey.
