    Thanks to Bruce for such a great interview. Take care, Shane
  • @manlikegt
    Soo interesting to hear experts coming together to try and dispel some of the common myths which surround our industry. Knowledge is power, thanks again for open and honest content.
  • @Richard-4
    Everybody needs to listen to Bruce this man is a genius of light on plants 🌱 💡. there is math and science behind everything if you open your eyes
  • Very interesting information, Migro is for sure a honest trustworthy company. I trust the quality of there lights along with there honest approach makes makes me want to buy one of there lights.
  • @jonnflores8345
    We need more and more of people like Dr. Bugbee. We need actual science to help the lighting industry grow...which will benefit us...the consumer. It's all been so hot and miss up until recently. We purchase light and have to trust that the marketing claims of the product are sincere. Without actual science behind it... we have just been buying what appeals to us ...or...what we thought was the best bargain....then crossing our fingers and hoping it was gonna work! People like Dr Bugbee and Shane are much appreciated.

    One thing about this interview it was about the best I have ever seen done with Dr. Bruce. It's all about the questions you asked. No one as of yet has had the intelligence to find out as much valuable information as you did. The show is amazing thanks to the intelligence of the man doing the interview! Fifty potential shows in all this info.
  • Fantastic! Thank you so much Dr. Bugbee and MIGRO for bringing his findings to our community.
  • best interviews by two great teachers , both are awesome for advice
  • @EdlundInside

  • @tonyfanfarone
    Thanks for the education. This man is great at explaining his answers to questions. Rare.
  • @ddtblack
    Extremely interesting and captivating! Thank you so much for sharing this knowledge! Do you reckon there might be a part 2? I'd love to hear more about far red, and how to implement it efficiently into a grow (what time of the day/night cycle it should be used, what stages of plant development it is more beneficial for, what impact it has on plants on a metabolic level...), along with stuff such as Emerson effect, or possible benefits of high CRI lights, versus the obvious disadvantage of a lower PPF/W. Please let me know, I'd love to watch another video as instructive as this one!
