Dr. Petty - "I want to thank Barry for making this video, but I misspoke twice in the video. The greenhouse lumber was $284, not $200. The greenhouse polyethylene was $111, not $50. So the $300 estimate should really be $400. Automatic vent openers are $35 each if needed." Dr. Petty's Optimum Wisdom Laboratories: optimumwisdomlabs.weebly.com/
