Adjustable light spectrum LED lights

Hi everyone I just wanted to check and see what others are doing in regards to LEDs that have adjustable spectrum? I have a few different LEDs that I use for my garden. Obviously not planned that way. Bought one and have been gifted the rest. So there are a few that are full spectrum lights although each varies slightly by manufacturer. Then I have two that are adjustable. For the adjustable units I have been working with the light recipes provided as there seems to be one for each stage plus some that are generically listed so as I don't know how they would affect the growth I haven't used them. I would like to know more about how the changes in spectrum affect growth outside of "blue for veg and red for bloom". Is anyone else using these types of LEDs? Are those that are , are you using the spectrums programmed by the manufacturer or have any of you put together your own? Are you adding UVB? Perhaps if I check the different manufacturers of these types of LEDs I could compare the available spectrum recommended by each of the manufacturers for different stages?

You are in a great position to experiment with them all and maybe you'll come to the same conclusion as me. Plants care about light, ADVERTISERS and FANBOYS care about spectrum. Imho yes the light bandwidth does play a role, but it's far more important to give the plant wattage and even par spread, than to have some super specific color of light. I buy cheap Chinese "full spectrum" cob lights and rock the house with them.

Lol ok it's "just stupid" to buy the light with the most actual par spread and to ignore marketing gimmicks about different spectrums. I guess it's "my loss". We're trying to grow weed. Max light. Spectrum means fuck all. I've made my statement you can go ahead and pay extra for some cute diagram of a light bandwidth that some guy originally pulled out of his ass. Be my guest. Like I said. I'll just be over here with my cheap Chinese LEDs that grow the same pounds of dank for even less power draw.

If a CFL had the perfect spectrum it doesn't mean it can throw the light farther that 4 inches with any effectiveness. Apply the same theory of thought to realize that spectrum not only isn't everything, its actually one of the least important variables in your grow. Put your money into good liquid nutes abs better ventilation before you upgrade you're LEDs from Chinese Amazon cob arrays.

You do realize the sun has a full spectrum.... Why would you not want to replicate the sun if you could? Of course PAR spread is important, and yes, arguably more important than light spectrum. However, that wasn't what we were actually discussing, which was is light spectrum a gimmick. Stop straw-manning the discussion. You're all over the place with your opinion of full spectrum. First, you said it was a gimmick, but in your last reply you said its the last thing to worry about, which implies you do have to worry about it. Therefore, it's not a gimmick, and you should be weary of how you explain things to others who might actually take your bullshit half-ass answers as true to heart.

Lol. There are plenty of growers on this forum who have pulled good weight from CFL's all things considering. There are plenty of growers who use HPS lights, which can penetrate much better than other lights and can't pull a pound. Everything is important when growing quality cannabis, not just what you feel like.

That's exactly what I'm saying. I didn't bash cfls. I'm saying sometimes these are apples to oranges discussions sometimes and do what works not what marketers want.

Btw the term "the last thing to worry about" means it's not important. That's simple English you misunderstood just now dude.

Also, no. Not "everything is important" spectrum is not that important. If u think so cool. I'm just trying to answer the op's question. You guys are arguing with someone for sharing an opinion and you're making yourselves look really ignorant. I have experimented with everything under the sun including the sun for lighting and yes sun is best, but use what works for you. My 2 cent is look at actual power draw, actual par spread, and actual cost

Holy shit. You're original comment said caring about spectrum is a marketing gimmick, not that is just less important. THAT IS FACTUALLY FALSE. It is not a gimmick and is something to be considered when buying lights. Calling people fanboys who care about spectrum is also stupid. Once you have your grow dialed in you always look for something that can give you an edge and make it better, or maybe you personally don't. You could add UV? Add Sidelighting? All of these could be considered less important. I mean, the list goes on. The fact is, they do help you're grow if you know what you're doing, which clearly you do not. That is literally all we were discussing and you can't wrap your head around the fact that you were wrong. Lastly, you personally grow with "Full spectrum", so how do you know what benefits you're getting or not getting?

It just a matter of time ( IMO soon ) that led boards will finally loaded with multi spectrum leds .

There are rigs running combination “ white light “ engines ( one a little bluer than the other ) .
I think there will be a BOARD offering 2700/3000/3500/4000k led chips in the future all on one board. Royal blues / deep reds / far reds are already an option and can be easily added to any grow setup via strips and pucks.

So expanding on your own setup is pretty easy. UVB diodes are available and so is T5 lamps for UVB BULBS like repitilsun and Agromax. Even reptile bulbs are available for the grower .

HLG has a 5000k board too.

I run Amazon cobs. 100w chips that draw at 50w max and have variable voltage knobs. Various manufacturers undercut each other constantly so I'm price concerned not brand particular. Just look on Amazon or Walmart for "cob led grow light" I think I payed around 120 or 140$ usd for a 6bulb that draws 300w and payed around 80 for the 200w draw 4 bulb Cobs I'm adding on in addition. They just use b or c bin cobs that are only slightly less efficient than the 1500$ competition.

I've also got a dormgrow g8 450w that actually draws 340w and the 300w draw cob from Amazon draws less watts, is stronger, also adjustable, and a third the price of the dormgrow

Light is light plants are plants and side-by-sides are God.

I did a side by side (all praise be unto sbs) and white Chinese led grew more than the blue red China led. And more automatically = better of course obviously without a doubt as a matter of fact.

This was on other plants but plants are plants so whatever
