This Collab Series is exactly what ive been looking for, explaining specific more niche questions the community has had but very directly! Thank you guys!
I found that this stretching effect is very much genetics dependent. For example, the Master Kush Auto and other Kush sorts will not stretch at all with extra FR whereas Northern Light stretches as fuck.
i found that when using far red lighting, my internode space increased significantly. great implementation especially for cannabis vegetation. love this collab!
Some genetics seem to respond to relatively high PAR levels with compact growth, short inter-nodal spacing, small leaves and branching habit when in vegetative growth. Other genetics are less severely affected. Additional far-red helps greatly to extend the nodal spacing. This give the grower total control over the shape without having to reduce PAR if the grower desires fastest possible growth. Also great on pre-flowering plants shortly after transplant to quickly fill the room for more efficient use of electricity, shaving days off the veg cycle. If stems elongate too much, turn off far-red and increase PAR. Btw, cheap light meters usually cut-off at 700nm so don't measure far-red.
I added some Mars Hydro far red LEDs for side lighting only in flower and grew some of the best bud ever. There is a lot of blue in the tent as well. I didn't notice much stretching. Maybe the increase in ppfd on the side offsets the stretch response. Great video thank you.
Hey professor, I know this is a little off topic from the video but I figured you'd be a great person to ask about this. Do you know any great resources for finding optimal PPM ranges for all nutrients in a good hydroponics fertilizer for cannabis (bonus points if it's in coco coir with the Ca and Mg concentrations). I see wildly ranging ppm ranges, especially for nitrogen and I'm wanting to improve my fertilizer game. Thanks a million and please keep making awesome, science-based grow videos.
In short get a ppm (or EC) tester to find out what you are adding. For Nitrogen aim for 100-120ppm as a starting point. How to get dialed in you may ask, check out this DeBacco University video... ua-cam.com/video/ZLh5zXCqkw8/v-deo.html

I already had a good idea that red and far red wont flip plants. Because if it did, home growers of every experience level would be complaining about it non-stop.

Happy to provide valuable content!
Love these recent collaborations Professor DeBacco, all of your videos are very informing to those of us keen to learn!
Great to hear you have liked the series!

Autos are trash and also a different species
@@ObjectiveMedia LOL you have no idea...
Thanks for sharing your experience.

Thanks for sharing your research experience @kannakiera8928

The blue light will also help reduce stretch.
Thank you Matt! Awesome information on this channel!! +1 sub.
Thanks for the subscription and comment.
Thanks for the info. Your videos are always helpful and informative. Thanks again.
Great to know, thanks for commenting!
Such quality information! This channel is a great resource.
Much appreciated!

I always love learning about how my plants respond to their environment.
Happy to provide the quality content.
is there any truth to utilizing far red to speed up changes in phytochrome state in short day plants?

Great video. Thanks Professor DeBacco 👍
You are welcome!
Valuable and dependable information. TY
Glad you found it.

I think this is an over-simplification, it causes photosynthesis and FR is present in sunlight
@@m.streicher8286 What part of what I said is too simple. Excessive FR wont flip a plant to flower. What more do you want out of that.
Be careful with the amount of red light for sure.
