Professor Erik Runkle is a grow lighting expert in the horticultural department of Michigan state university and shares with us the latest research in Horticultural lighting.
We discuss his research facility CELL, the Controlled Environment Lighting Lab in MSU and the latest research results.
We also overview the difference between light quantity and quality (spectrum) and the effects of difference plant spectrum on plant size, yield and shape.

shane your are truly something new to RU-vid. your videos have such good quility and give such an extent of information. I hope you continue doing stuff like this. the future is looking green and I can see ppl in 10 years still watching ur videos for information just because of how organized you and your videos are. this kinda video shouldnt be free on youtube IMO. but very happy it is :)

@briankelley7918 4 года назад

80s and 90s when we had metal halide and hps We had a green light in the ceiling light so if you wanted to go in the room when a light was off you just turned on the green light so you can see. Little did we know without RU-vid. It was tough tough I tell you living in the 80s. But the 80s for an awesome time people cared about one another.

Really solid discussion/video, learned a lot, thank you much. It's especially useful knowing that full spectrum affects seedlings, setting them up for success. After a month of research and absorbing the internet's "common knowledge", I feel like this video and the other masterclass with Bruce really cleared the cobwebs and helped me understand.

@animalmother4066 4 года назад

Thanks for the generous information, it really opened my mind to new things when growing flowers or what have you with LED. I've recently started an indoor grow specifcally for shrubs, pine and other specimans that I brought home from Northern California especially the shrub ceanothus because of its heavenly fragrance and goregous appearance. LED's have come a long way and they'll only keep getting better.

Good job Shane.. hats off to you. With all the info out there it's hard to get a clear look at what to do to maximize your efficiencies tailored to the growers personal taste. From what I could tell this was a no bullshit interview looking without bias at one man's scientific observations. I'll probably have to watch it a second time to absorb a bit more. I'm not a light nerd but I an interested in knowing exactly how my lights perform compared to what else is available. Ha, maybe I am a light nerd! Always interested in vid's like this.

@circle4922 4 года назад

Hi, This is another *excellent* video. Thank you both for both. Shane, do you think you could make a copy of that.."normalized" spectral graph you made available for download please? (I think you referred to it as once) Where you took all the spectrums of various lights and scaled them to fit them best as you could onto on the same size axis. It's amazing to look at the the hps vs white led example that you show in this video and think how effective hps is. It has uv and ir, though wouldn't the uv be almost *completely* blocked by the glass bulb? Thanks again.

@timpage5021 4 года назад

Hot tip As you get ready to flip your plants into flower instead of 12 12 immediately lower the amount of light in 1 hour increments for the first 10 days. After 25 years winter gardening it mimics the shorter days in autumn and is less stressful for plants. Another way is when you turn your lights out turn em at 17 and half and have a red light on for the last half hour.

@30:00, the plants on the right had more intense light, correct? With the more intense light, did you increase the watering and nutrients too? Its my understanding that when you increase the light intensity you must increase the water and nutrients also.

@greenthirteen5356 4 года назад

@horlacsd 4 года назад

as for the blue light + stem elongation in lettuce (as the exception) -- possible explanation the plant is trying to get more red . the sun's rays have more red content when it arrives at oblique angles (more Rayleigh scattering of the blues). a short leafy green like a lettuce might stretch to catch more oblique sunrays.

@greenbfingers 4 года назад

Shane excellent content as usual , Unbiased information. Could you please check out the Maxibright 3k 600 w E40 Cmh bulb ? Maxibright are advising using them with old style magnetic ballast, as newer digital ballasts operate at to high a frequency. Bulb is £95 & you can pick up a decent new magnetic ballast for £20-25 & a Euro reflector for £10 . So £130 for a full 600w cmh kit. Would appreciated your unbiased opinion. Still rocking my migro 400 + "top notch light"

i have some mean petunia's growing too. seriously though, i'm actually trying to code a grow light/photon simulator in javascript (in 2d front/side view) and i'm looking into making a plant growth algorithm maybe in the futuere. the sim got heavy real quick though so i'm rewriting that stuff for multithreading, but since sharedarray has been shitlisted from browsers due to spectre/meltdown vulnerabilities, i have to fix some kind of long polling approach and find the quickest ways to merge sets, sending flat arrays without it hopefully all going to shit because of sending large datasets, i would love to see more than say 40k of them bastards. may have to write them back into an noise texture-ish image, duplicate that, then remove the excesses outside the bounds per pixel, and color cycle that or so anyway, now i still have some questions about DLI :D

@kimodland 3 года назад

The problem with the lighting picture is light leak. No isolation of sperate light source. Some will feed off other lighting. How can you judge lighting without control isolation grows?

@robbstark8275 4 года назад

Shane, thank you for your work! Could you make your lights programmed to behave more like sun? I mean gradual rising of the intensity and then gradual declining.
