I was indirectly asked this question via a search engine earlier this week. The person who was wondering typed that question into Google and asked "Will green light kill your plants?" I've never heard anyone ask that question before and was wondering if there is some sort of discussion going on somewhere to that end? I've done my own research and recently posted a response on my plant website but would enjoy hearing any other opinions or comments. Especially if this question is on some plant forum. Thanks! I'm adding this amendment: Some have emailed me asking how I was "indrectly" asked a question via a search engine. You likely don't know it but everytime you type a search into any search engine there are companies who log what you ask or search for. When a search leads you to a specific website the owner of that site can have the ability to see what question you asked, but not who asked it. The information is used to improve the content of the site.
