As always another great video. Bruce Bugbee is an amazing asset to the growing community as a whole. Agricultural and personal small scale. Take care stay safe and peace.
Thanks, the goal is to take some of the information already shared and summarize it and also apply it to actual growing situations to provide people with relevant and scientific based content.
The wavelengths outside of the PAR/PPFD are achieved in my grow room by using 'Finishing Bulbs'. I use 2 types: 1. A high UV MH 1000W bulb, ( less than 400nm ) and barely any infra-red and yellow spectrums, ( 750nm - 550nm ) the last two weeks of vegetative growth. This improves flavors and aromas. 2. A high IR HPS bulb 1000W, ( greater than 750nm ) the last two weeks of flowering. This is in agreement with Dr. Debacco's data as this causes the calyxes' to swell 35% - 50% more than if just kept on a Full Nova spectrum HPS bulb, thus increasing yield gains per SOG/SCROG ratios.
Thanks for sharing your experience, there will be a video coming out soon comparing some of the options regarding CMH bulbs that will be similar to the concept you have shared here. Great to see contributions from people in the comments!
Incredible channel! I was really angry that YT would not let me watch this because it is Cannabis-related (I am located in the EU). VPN + Script solved my problems fine. As you did with my lightning-questions! Thank you so much!
The light intensity won’t decrease by 25% it would be 75% for a given area at twice the distance. You would be only receiving 25% for given area at twice the distance
I just added a UV/IR light to my grow, the Mars Hydro UR45. It seems the UV is UVA. They are on independent on/off switches. I'm trying to figure out how often and when to use them during the grow. When would you recommend using the UV/IR during the grow? This will be for autoflowers. Thank you!
Step 1 would be to reach out to the manufacture to see if they can provide any recommendations. UV and IR are what outdoor plants naturally get so the plant can use these spectrums.
hey brother i have a question, i have 4 plants which are sitting at 300 ppfd and they arent stretching much and im about to flip them to flower, for the preflowerimg stage (first 3 weeks of flower) should i keep the ppfd low for them to stretch? or give them the ppfd needed? im scared that they wont stretch if i give them the ppfd needed right now
Ive got a lumatek zeus pro 600w led ( known as the photontek x 600w pro in the us and canada ) It gives out a PPF of 1620 µmol/s at full power. It comes with dimmable adapter and was wondering what sort of output i should be looking for at different stages of growth. I don’t see the point in amping up my electric bill by having the lights at full 600w power throughout seedling and veg stage if it doesn’t need it. What would you recommend through different stages of the grow. It has 25%, 50%, 75% and 100% adjustments. Any feedback would be much appreciated 👍🏼
First I’d like to thank you for being so responsive this week with my comments, I have a quick question that I hope you can give me some insight on. As I sit here and do a bunch of math using PPFD maps and calculating the DLI I can potentially achieve with various power levels, distances, and light schedules, I had a question. If I assume that 12” provides 100% intensity, (as per manufacturers directions for LED light) and that double the distance, 24”, provides only 25% of that intensity, could I work this equation in reverse? For example would 6” then provide 400% of the light intensity? I know that is extreme lol but even if I could achieve 150% of my potential PPFD from my lights it would allow me to bring my photosynthesis up to an optimal level without purchasing any new equipment. Thanks so much for your informative video!
In theory your math and thought process are correct. However, what you are not taking into consideration is the light intensity and coverage area since when you are talking about plants this is also another important factor. Intensity over what coverage area based on the distance to the canopy needs to be factored in as well;-)
@3:23 confirmation to why par meters are this industries biggest scam, its still light intensity at the end of the day, as it doesnt take into factor 400 < or
The key is to keep on learning and if you revisit this video in the future it may prove to be helpful for you. Keep wanting to learn more and you will go far!

Something that I certainly need to invest some time in learning. Thank you Professor.
You are welcome, you can also use this video as a reference/reminder as it has a lot of fundamentals covered.

Glad you were able to find a way to make it work for you!
Still a reference Professor ! thanks again
Glad to provide quality and time tested content!
Excellent video, great job explaining a complex topic.
Glad you liked it, you have described the goal of this channel;-)
Outstanding Professor ,thank you
You are welcome!
Im going too have to watch this video again.😄
Pause, take notes and rewatch.... this additional time spent will be worth it;-)
Love this research i used it when i was shopping for lights. Great video!! 🔬👨🔬🤙
Hope this helps you become an informed and educated consumer.
I'm really loving ur videos keep em coming man 🙂✌
2x daily content can not last for ever, but enjoy it while it is here;-)
Great video-im glad i found your stuff! keep up the great work!
DeBacco University is happy to be found by you, please help spread the word about the channel to others!
Thanks for the video!
Thanks for watching!
Did you talk anywhere about the idea values for the plant in question....that is what we were all hoping to learn.
This continuation video may help answer the question you asked... ua-cam.com/video/uAQ_he6bEoY/v-deo.html
@@DeBaccoUniversity That link was very helpful and explanatory. Thank you very much sir! You are the man.
Danke!
Thanks!

"...when you double the distance the light intensity decreases to 25%"

pleasse
In short... give them the needed ppfd.

What would you recommend through different stages of the grow. It has 25%, 50%, 75% and 100% adjustments.
Any feedback would be much appreciated 👍🏼
The % do not mean much, you want to measure what your plants are getting in PAR at plant height. In short flower should have the highest PAR readings.
@@DeBaccoUniversity thank you for feedback, very much appreciated 👍🏼
Thanks
You are welcome!
You are priceless
Thank you for this high praise!

It’s all about DLI
Tune in tomorrow May 13th, 2021 @ 11:00am ET and there will be a video going into detail on this very topic;-)

They are a tool to use, but growers need to understand the limitations of any instrument they are using.
@@DeBaccoUniversity no doubt, just sayin, $155 cheap end, to give crunched numbers with fuzzy math,
This is beyond me
