I use far red indoors at the beginning and end of the light cycle to simulate the sunrise and sunset. It will help slowly wake your plants as well as help put them to sleep much better than a sudden on/off of the lights.

I don't mean to be know it all, but you can check it out if you are a plant enthusiast. It's more of the type of crop you have. If you have a short day plant , an increased "dark time" that induces the flowering is not really because it "sleeps" or "rests". It's more of another photoreceptor, called phytochrome. They're quite similar to chlorophyll, wherein it absorbs certain kinds of wavelength, in this case, it's capable of absorbing red and far-red. Unlike chlorophyll however, it's purpose is not to produce energy, but to determine and signal that it's time for a developmental phenomena (e.g. flowering, germination, shade avoidance, etc.). How? Well it depends on the light composition. When red light is abundant (bright), phytochrome takes the "Pfr" form which is flower inducing to long day plants but flower inhibiting to short day plants. When far-red is abundant which is typical under darkness, phytochrome takes the "Pr" form, which in this case is flower inducing to short day and inhibiting to long day plants. Cryptochromes, blue light absorbing receptors, play also a crucial role to flower induction, they can also be a something on their own but also highly intertwined with phytochromes. How the plant translates this to the florigen production is a whole lot (and diverse)of processes from protein and genome interaction. It's an extensive field, but a lot remains elusive even within the scientific community. :)

That is my understanding as well. Unfortunately, it’s only anecdotal. Most people do 12/12 to induce flowering. Years ago I heard of an acquaintance of a friend in the 39-40 latitude of Northern California using a red light at sunset to induce flowering Blue Dream during the middle of summer, rather than pulling tarps in a light dep. Have you experimented with this? I’m curious how much and how long the light would need to be on, as well as what brand/intensity. I’m assuming 15 to 30 minutes in the evening would be a good starting point to test.

Hello , thank you for sharing this but i believe that i have a total different perspective on that subject.Let me elaborate ill put also to the "for" section that u actually get a week faster on higher percentage of far red thats a plus for cannabis at least from a manufacturing perspective.Also u are actually seeing far red as a solo acting light and thats what mcree did but he had no gear or tech. i think that if u regulate the uv and blue percentage u can find a sweet spot and have the same or even better results. Lets say its even on yield and you add co2 and help the metabolism and we know it was a week early from the previous study that shows me faster metabolism of the plant in general so the additional co2 would lead to additional photosynthesis that would led to bigger plant biger overall mass and thats for me more yield.also on your "against" i would say that there is no mass production on far red so the chips are expensive and not putting that much out but i believe the market will get there as it happened with the white led chips 2 years ago. Lm301b nice chip effective and cheap but its on a production line.and if there is cell expansion why it would stop at leaves ? buds dont have cells? Its not my field of expertise but i read alot of articles and studys especially dr bugbee cause i think his research atm is top at his field.I believe we will see the first results in a month or so and will have alot of testing for companys producing cannabis in the us at least.Love to hear your opinions on the subject.Awesome videos and also would like to ask u what do u prefer atm as far as tech goes strips to cover evenly the area or board like designs? P.s Another food for thought as i would like to say . uv according to bugbee study is absorbed and the plant start to get a tolerance to it producing more trichoma etc so if we find the sweet spot on that and make a more resin trichoma plant and then we cross it again with another pheno with the same plus charachteristics wouldnt that give us a plant with higher resin and trichoma production?

Good studies at Utah State. Been doing my first experiment with lots of far red. Yes, my plants are stretched, but the buds fill in all that streched out space, leaving large nugs all over my best plant. Not only that, my tricombs are almost double in size from my last grow with UV. The main test will be the product quality. If you buy a normally small auto flower, I'm guessing with far red, it will not be a small plant, it will increase the size by double.

In Woodland, Bluebells flowering is triggered by %far-red which increases as leaves develop on the trees above. As you explained, far red travels through leaves, thus the full canopy forest has high far red at ground level! Theory: Establish a good canopy with your plants and keep your hands away from removing Lower leaves until flowering has been established, for a few weeks, at lower nighttime temperature = less stretch more yeild.

If you’d aim for enhancing flower size of a plant which a cannabis grower might want. Would it be beneficial to add far red radiation during the flower period only? I would imagine that you could get a nice compact growth during veg and then kick it off with extra levels of far red. How might this play out for sprouting plants during the cotyledons stage? With the look out on microgreens which are tightly sown. Could far red result in a more even groth? If you Push density, there are often sprouts left behind below the canopy which can start rotting.

I also run it last 15 minutes to try and trigger phytochrome switch or trigger "sleep" in plants, but running 11 on 13 off i dont think there is huge benefit to it in shortening flower period.

If you screw off the lens, it becomes a lot wider and more even although still rather narrow beam, but how would these compare to a 660nm top bin diode? I’ve started experimenting with the this wide red laser line placed 1m above the canopy. It turns on 20 min before lights out and turns off 10 min after lights out. I’m thinking it could be very useful for bloom initiator and/or bloom enhancer. Would love to see some measurements!

The problem I see with that is that it’s not because you have faster longer stems that the buds will actually get bigger. When cannabis is stretched during veg, it’s often a sign of not optimal growth , hence reducing the end quality of the product.

@@sigmastodon I think that if 10% far fed is enough to make your plants stretch that there is something missing in the blue range of the spectrum and I also believe that far red is more a metabolic trigger than photosynthetic. The sun depending on where you are and what the season is has far more than 10% far red and I don't think God got it wrong, Light spectrum is a recipe and if you can duplicate the sun you are doing it right.

If you add in additional UV with your IR would it help the photosynthetic ability of the normal PAR grow light. Given the other variables like nutrients and total environment were fair.

The far-red effect is plant species dependant. NOT all plants will grow taller, some such as spinach/lettuce for example will grow broader, resulting in increased yields. Also, far-red elongation effect on the internodal spacing might be linked to an earlier flower-onset in some cultivars as well.

Those far-red percentages of light sources you have listed here are based on energy flux not photon flux, right? I've read in an article by Bugbee that natural and cool white LEDs have 20-25% red photon with R:Fr ratio of 5-6 respectively... so Fr flux of white LEDs is about 4% not 2% if we report the flux based on number of photons.

So this video begs the question what does this mean for the ES 180 V2 or the 300 watt version because I have the 180 V2 and I have to say I do get a bit of stretching but I still get solid flowers.But this video makes me wonder alot because as you said all indoor growers want more compact flowers with better density does the electric sky in your opinion fall into the light category that causes to much stretching?

Hi Shane, have you ever done any experiments by introducing far red (~730nm), just before day end and again at start of day cycle? Some reports saying this simulates sunset and sunrise to the plant. Helps plant get to sleep a lot quicker (vastly simplifying the photochemical reactions of the plant) and wake up faster. Pro grow tip I’ve read too. If so, can you recommend a bulb? Thanks.

Hi sir, i'm not an expert of geraniums, maybe there are other varieties. But aren't they usually day neutral plants? In most journals, day neutral plants are always not studied. There's always a trending theory that day neutral plants can flower by simply neglecting the usual short day and long day mechanisms and simply depend on its age. OR, from your experiment, you may hypothesize also that a day neutral plant can become a day neutral plant because it is capable of the two possible mechanisms to induce flowering, short and long day. So the long photoperiod (18 hours) that you have given promotes the long day mechanism, and your added far red light which fools the plant to perceive "darkness", using phytoreceptors callled phytochromes, also induces the short day mechanism. But i may bet that the long photoperiod is more related blue light signalling.Maybe that is why you have increased/early flowering because florigen production is overly encouraged with two promoting mechanisms going on. That is just my two cents.
