This for all the LED haters! Is that blurple I see kicking HID butt?

Here is an unbiased commercial grow with actual test results. HID lights are a thing of the past. Even the cheap LED lights can out grow HID lights now.

Enjoy the results video.....(lol, and its almost 4 years old!)

You can watch the first video that shows the grow and all the energy and heating issues before the results video if interested. Just look at the only other video they have posted. It is titled =
LED vs 1000W Double-Ended HPS Medical Cannabis Grow Test

LOLOLOL enjoy your shitty burple

You got laughed out of the last thread so now you made another one? What a glutton for abuse!

Why dont you say it again for the people that missed it, your opinion on the old burples vs the new full spectrum white LEDs. That's my favorite part!

Not all LEDs are bad, but the ones your using and promoting ARE

Didnt BML change there name to Fluence and also discontinue that blurple spydr line for the white LED spydrx line at around the same time? wonder why...

OP,

Don't mean to challenge you here. Just want to ask you a few things, because you say you studied electrical engineering.
Just found this video a few days ago.
Could you please explain this video?
Specifically the energy efficiency comparison, and PAR spectrum?

I'm personally inclined to think the yield in your video was due to canopy temperature. Not PAR quality.

:peace:

Ya my kids laugh when they are called out too. Its a defense mechanism. Wasnt laughed out of anywhere. Just not fun chatting with morons. Just gonna make posts so people who have a brain can see HID are a thing of the past.


LOL those so called 'BAD' led lights still beat the HID easy and if you say there are 'BAD' , then by that logic even the bad ones beat HID.

I was pushing the LED tech over HID. Didnt say the ones I was using are the best. Try reading.

Just let go. You cant beat science. LED will always beat HID!

Who cares if its purple or white. It still beats HID! Its the technology thats important. but you will just want to complain about something, get off the purple issue. its about LED's (This is NOT from youtube richard)


Academic research into HPS vs. LED for cannabis cultivation

Cannabis cultivators find themselves in a dilemma called HPS (high pressure sodium) lighting versus LED (light emitting diode) lighting. On the one hand, HPS has been around in agriculture for a long time and has proven that it can successfully grow a wide variety of plants. On the other hand, LED, as the latest entrant to the horticultural lighting market is living up to its hype. What cannabis growers are concerned with are quick growth cycles of cannabis plants that yield many large flowers, containing high levels of THC (Δ-9-Tetrahydroannabinol), CBD, and other valuable secondary metabolites. Furthermore, growers need a lighting system that produces consistent results time after time as well as proven light recipes. Up to recently, no academic research had been done to compare the capabilities of these two lighting sources for growth of cannabis.


Photo taken at MJardin, Denver, CO. Plant grown under the Valoya NS1 (sunlight) spectrum.

An academic research titled ‘The Effect of Light Spectrum on Cannabis Sativa Morphology and Cannabinoid Content’ (G.Grassi, G.Magagnini, S.Kotiranta) has been presented at the Cannabinoid Conference in Cologne in September 2017 which presented a two-year long comparative study of HPS versus LED lighting for cannabis cultivation.

The results show that the morphology of Cannabis sativa can be manipulated with light spectra. Plants under HPS treatment were taller and had more total biomass dry weight than treatments AP673L and NS1 (spectra by Valoya, the Finnish manufacturer of LED grow lights). HPS light spectrum is low in short wavelength irradiation (blue and UVA) and rich in green, yellow, red and IR in 800-1100 nm irradiation. This type of wavelength combination resulted in longer internodes and therefore taller plants with more stem dry weight. As for the compound accumulation in the flowers, treatments NS1 and AP673L had higher CBD and THC concentrations than HPS treatment. Treatment NS1 had the highest CBG Level. Spectrum NS1 is rich in short wavelength irradiation (blue and UVA) and had the highest R:FR ratio of all tested spectra. In addition to high cannabinoid content, spectrum NS1 enhanced the compact growth habit of the measured plants. The research suggests that the lower wavelengths, blue and UVA, could contribute to the higher cannabinoid yield in treatment NS1 compared to AP673L and HPS, respectively. In the rounds of the research the amount of THC produced under LEDs ranged from 26-38% more than compared to the HPS treatment.


Three light sources were compared to each other. Spectra of the used light sources from left to right: HPS, AP673L and NS1.


Plants under LED spectra were more compact and produced more cannabinoids than the HPS light source.

For more information on this research please visit Valoya (booth #523) at the upcoming Marijuana Business Conference and Expo in Las Vegas. One of the paper authors, Ms. Kotiranta will be present at the booth.
