That seems like a total waste of time. Spending time trying to get strips setup inside the plants. When you can blast them with HPS and get the same penetration. And grow a tree. Or use mid power Samsung strips, cobs, or bridgelux strips. Cheap leds dont grow good pot. You have to worry about cooling. And light bleaching bc the lights are so close to the plant material. And who the fuck would put an electronic device that uses power down on the soil. With moisture and whatnot. This just seems like a fire waiting to happen. Just build you a decent led mid power light. You'll be happy. They rock like crazy.

Some interesting ideas and observations. Some plants it would be nice to control the stem height. Whether the blue light trick works I don't know, but would be cool if it did. Green does penetrate better, but it also reflects better. I would need to see some real world data before I put any meaningful green levels in on purpose. My ideal flowering spectrum would be about 10% blue and the rest placed between 580 and 680.

Blurple will have it's day!

I don't think you read the whole post tbh..this is more about light spectrum not leds vs hps.
I am well versed in leds so understand what u are saying.
This is about light spectrum and using different spectrums on certain parts of the plant to elicit hormonal and physical change like shorter node spacing or leaf size.

As for fire! super angry guy is a dab hand with electronics imo and he explains how he encapsulates the led strips in epoxy to avoid moisture issues.

I thought there would be more interest in the idea of using spectrum to control hormone response....this guy claims he has spent 5+ years playing with the concept and has looks like he has had interesting results.....even seems to be trying to patent it! so there must be someone else here who has the knowledge to explain why this won't or will work lol I might just have to play around myself!

Its a very interesting approach. Blue light is mostly use for signaling and it don't needs much blue to see an effect. You need only 10PAR/w of blue wavelengths per squaremeter to keep the plants compact and support branching. I've seen such short nodial distance under blurple fixtures with lots of blue light like the Viparspectra LED's.
I've done my own experiments with additional blue 420-430nm LED's and the effects are clearly visible. Also the terpene profile is changing with more blue wavelength.
The diodes he has used are the cheapest he could find(3ct) but there are many other cheap solutions one can use.
These 12v, 1,2w modules for instance are available in different white spectrums as well as with red, green, purple or blue diodes and you can get them pretty cheap. And they are IP67 rated and run with a 12v driver so there would be no risk causing a fire. Maybe one or two modules mounted in the area where the stems are still soft are already enough to cause an effect and these midpower diodes would cause no burnings even when touching the stem.

Its for sure worth a try. 20 of these modules you can get for less than 10 bucks and we all have a 12v driver laying around and if not, a 12v/1A wallplug power supply costs 3 bucks shipped and is enough for 10 of these modules.
Maybe a trick to win the next party cup competition, lol! The plant which is grown with multiple nodes per inch looks deffinately like a keeper. I have a little 3sft area for testing pourposes and these modules are already on my wish list. I've a few stretchy sativa strains currently(BlueDream, SSH and ColumbianGold/LemonGreen) who actually offer to try it out.

The effects of different light on plants has been studied for years. You should look at some real studies somewhere other than grow weed easy.
Google Morphogenesis.
This article touches on it https://gavita.com/retail/app/uploads/Light-Matters-5-GCM_US13.pdf

I see what ur saying I've spent a lot of time on the gavita site so have read the article posted that whole section is such a good resource!
I only shared the GWE link as the guys reddit account hasn't got the pics anymore n thought peeps wld rather it was complete.
We all know blue light helps with the stretch and there are loads of studies out there that's show effects of using different lighting on the whole plant but this guy thinks there are benefits to specific light spectrums on certain parts of the plant while using others on other parts like larger leaves and I've had some pretty tight nodes but the results he's getting are crazy!
Cld be a good way for those microgrowers out there to get some short fattie plants! o_O:eyesmoke:

Niiiiiice I am well interested in the results! It would be crazy to be able to get some of those lanky ass sativas to grow more compact.

I wonder if you could use the technique to like keep the main stem really short but have the branches stretch like hell lol! :eyesmoke:

When youre talking about differing terpene profiles is that something you have tested? Would be cool to see a side by side with lab analysis at the end.....im sure there are concentrate fanatics out there on the bleeding edge of this kinda stuff!

There are a few probs with lab tests, official side-by-side tests and so cuz I do this in a country where its totally illegal, lol! You can not even get seeds here and need to order them from another country.
But you can simply try it!
Get a small chinese 430nm 10w COB and a 10w/300mA driver(~5-6bucks) and mount it just above one of your plants so that only this single plant gets the additional blue light. You can see, smell and taste the difference.
One effect are slightly smaller leaves and a more intense green because chlorophyll is packed more densely. Buds also stay smaller and gets more dense compared to 3000°k w/o blue and therefor the trichomes are also packed more densely which looks impressive, btw. You also see more intense coloring when it goes to the end cuz blue realy helps to bring the colors to life. And when you smoke it it smells and feels like a completely different strain. There is no yield increasing effect but the opposide can be the case cuz the whole plants stays more compact.

It could maybe be use as a "FIM technique replacement". Let the plant grow until she has the needed height and instead of FIM'img the top add 2 blue modules around the top stem. You should get more twigs in this area and when you switch to 12/12 and the shoots get no additional blue anymore they should stretch out normal. Maybe one can reduce the need for additional blue to just 1 or 2 weeks and its already enough to create more tops.

I read loads of super angry guys stuff...
To me it looks like he was trying to get the most out of an older type of leds, using leds with narrow optics close to the stem etc.
I think you can probably get very similar results if you do a 2x2 vertical setup with 2 spectrums, one being blue heavy the other red/orange heavy. So basicly the bridgelux vesta strips...

Yea, 5000°k has more than enough blue to create very dense node spacings in veg. When using it from the side so that the stems get even more blue you should get almost similar results. I really like the Vesta strips and hope Blux will release a new version some time. The only downside is their efficiency but every time I talk about them there is another advantage of the tunable dual spectrum design.

BTW, I have ordered 10pcs 1,5w modules with 6 blue diodes each. Found them for 2,91$ on e3ay.
My cheapest project ever..

Brilliant! Will have to let us know how it goes!
