Since watching your videos my technique for indoor horticulture has improved greatly. The vast perspective of radiometry coming through your research has greatly improved my knowledge and understanding of growing cannabis. I have been growing cannabis since 1994 and have developed unconventional techniques that break the boundaries of the norm in commercial growing and produces immaculate results every time. Run-of-the-mill Warehouse grown dispensary here in Colorado is usually fairing mediocre compared to the buds I can produce. Since watching your videos over the last couple years I've gained a broader perspective of my technique. When I am tending to my plans my thought processes are now heavily influenced by your research. I tend to be a fairly observant person noticing minuscule changes and differences. Currently I'm growing two strains of cannabis in flower photo period, Scepter (Blue Dream x Gupta Kush) /IDK (70%/30%) and noticed two different reactions to the light on the surface of the leaves. Scepter, being indica dominant, has a bit darker green color than IDK. The leaves on the scepter is giving me about a 50% reflection of light off the surface. The leaves on the IDK plant do not give me any reflection at all. I can see the reflection not only by the light on the surface of the leaf, but also by the transparency of the leaf itself. These plants are grown under two 31K CMH bulbs. (I believe CMH lamps are the answer to your research on the effects of UV, IR and visible light combined). Philips GreenPower 315W 31K / MaxPar 315W 31K) powered by on 630 watt ballast. My question to you and your students is, do you know if the volume of light reflected off the leaves is determined by the plants genetics, and if so which wavelengths are being reflected and/or absorbed and how do they effect photosynthesis if light reflection off the leaves a genetic trait within cannabis subspecies?
If you can't measure it, you can't manipulate it! Loving all of these recent uploads and the great information that Bruce presents so well. Thanks for commenting on the cannabis connection, and I look forward to hearing any other observations in future videos.
You dont know how much helpfully can be real technical information about growing cannabis properly and your Channel totally its a way to make disappear all the myths in the internet about It. I must say im falling in love with growing plants with all the knowledge available in your Channel. Thanks for doing such a great job!
The results with the green background amaze me. I thought green and FR light amplify each other, i.e. there would be a positive interaction that would accelerate increase in leaf area and stem lenght. Intuitively, we could think that response to green and FR light are similar due to the increase of both green and FR light as we get closer to the ground in a canopy system. But since the slope of the graph for green background at 15:05 is smaller than the others, we can conclude - for this experiment - that green light and FR light do not interact positively. Which is amazing because, again, a young and small plant which is competing against taller plants has to maximize its leaf area and stem length. But here's the difference: Did you make the experiment taking the age of the plant into account? What if these responses change dramatically as the age of the plant varies? EDIT: Or could the smaller slope be explained with photosynthetical inefficiency, which leads to lower CO2 fixation rate, which leads to slower stem length increase?
Love these videos Dr Bugbee! They have really helped me understand the intricacies of lighting science, and in a very accessible and enjoyable manner as well. You are a great teacher. Please keep them coming!
I was growing hemp. I noticed some of the plants barely under a shade tree budded and got only a foot tall. While the others in full sun got tall and didnt bud till hours of light were cut down.
I've been watching and studying your work. Thank you for your tireless years of work and contribution to the agricultural community. I'm a student of light and a licensed medical cannabis grower. I love your work. I have one question. Why don't you have many studies or test using LEC/CMH lighting technology ? I use LEC lights with far red LEDs ( 630nm to 740nm ) combination in my flower room. I guess I have one more question am I wrong to use this technology? Thanks again.
I want a spectral radiometer for Christmas. I'm still confused on how a layman can approximate the % blue or far red. I want to toy with a far red product called "Buddies" which is a light string of 12 far reds @ 8.4W. (I think they are also coming out with a UV product.) Dr. Bugbee showed how deep far red penetrates so that factor adds another wrinkle. I have a large DIY light build for a 4 X 4 that has white + photo red. Would one string of buddies be overkill? I'd like to take a skunk pheno to see if I can make it taller using far red but will that have an effect on yield?
I’m curious if the far-red only influences stems and leaves. Is the effects specific to the tissues of stems and leaves or does it also apply to fruit/flowers? For example, does adding far-red help tomato fruits get larger? Or help potatoes store more starch?
So as a cacti and succulent grower it benefits me that there's no far red in the led grow light spectrum I use because I don't want elongation of stems in most cases as the plant becomes etiolated? Or have there not been studies to see how this affects CAM species?
Indigo, blue, yellow ,orange, red and beyond red is what my plants like. They like 9w/sqcm with higher indigo and red but blue ,yellow and orange facilitate full expression of genotype
Hey , I've data mined sum old ideas. One is higher pressure environment will dramaticly induce new genotypes not seen for eons. The other is electro-horticulture,,, a grounded container ,soil or water, with a electrode above plants with a voltage potential gradient will increase uptake of minerals and exchange of sugars and co2. Keep up the good work
I'm new to physics. Can someone explaine to me how dividing a 🌈 by invisible red equals a a quantity? Or is it a mass? I'm so confused as to how dividing multiple species of the existence of color equals anything.
Wouldn't the equation shown: Pfr/(Pfr + Pr) run from 0.2 to 0.8 in sun-to-shade rather than 0.8 to 0.2? Far Red penetrates into shady area more than just Red (and much more than Blue)
Yes, and the graph in the middle has the axes reversed! I was already having difficulty because of the mistake (we all make them) you picked up. Or is it? Argh the dreaded rewatch with even more attention to detail... In the morning though - Its late for me, and my devotion to this professor is total, but somehow not adding up to 100%

Yes. Far red is abundant in the autumn. Making it more effective on fruits and flowers. 15% more effective based on Dr.bugbee
