Why are so many new growers choosing blurple/led over hps/mh??

[Hust17]

Let’s not pretend this thread was going anywhere else. LED vs HPS, so classic. And another one just opened, oh joy.

 

[Chesspoker84]

Thats a very intersting thread for me, because i plan to invest some money in new lights just in a few weeks.
I live in germany, where i pay about .35$/KWh. So a very efficient light will pay out much faster than anywhere else,,,
ATM i run hps/mh and I'm happy with it, it is better than my old LED with 500w (was a quite expensive one, 4 years old).

BUT because i like to be as efficient as possible and i WILL have heat problems in the summer (currently 1600w hps...), i plan to get a quantum board in a few weeks.

Is this the right choice? What do you think? I think a 400W quantum, maybe even a "cheap" spider farm or even mars hydro (although i dont like this company) should replace my 600w hps AND give me a better light coverage. Thanks guys!!

 

[Hust17]

K god damnit lol... Give me like 10 mins I'll be back with a bar graph made to show that lizard lights increase thc% by 50%. But wait, it's not made by one of the most "reputable" companies so mine would be bullshit then right? That shit chart is not real data lol fuck the real data if they even tested their product is somewhere sitting on a desk that they don't want to post. I made real points here if you can't see that then you're blinded by your bias.

I’d like to take a second to shout out CALIFORNIA LIGHTWORKS! I emailed them as soon as this poster requested more data and look at this folks, less than an hour later, from the most reputable LED company on the market:

Tag @skanknodill.

My guess he’s chatting with his fellow kids on 4chan trying to get info on me. Give him a bit.

I never intended it, but that’s what they call WRECKED

 

[Hust17]

He also emailed back again to say:

Thanks for representing! That data was taken back when we were on the first version of the SS-1100. We are now on revision 8 which puts out even more light with the same power consumption.

Like I said earlier, the technology is always improving and will continue to with LEDs.

Ok so what in your mind is a legit comparison then? It’s as close to a side by side as you’re going to get, or are you saying they’re just blatantly lying about lab results?

I’m saying lab results are mostly arbitrary a stheee is no real standard atm. I can send the same big to 10 different labs and get 10 different results. Tbh a lot of guys do this with their product, just keep testing at different places until the results say what I want them too.

Well these happened at the same facility... I guess you could accuse them of sending in less than prime nugs for the hps if you really wanted to. Goodluck, I understand your skepticism

 

[Kassiopeija]

Nah the guy is making claims like an advertizer of leds so ergo he must be one ir he would simply realize his statement is bs...

First of all, I need to apologize to you for calling you an idiot a few days ago. I shouldnt have said. But your ways of finding an argument is just an unfair way to construct one.
Youre full of logical facallities. The above quote demonstrates to. "ergo he must be one" thats false. There are countless other motivational reasons why someone would have such an opinion.
Imagine someone doing the same to you. Suddenly you are a chinese vendor advertising crap tech from the 60s, last millenium. You speak like an advertiser, bring on the money now!
and theres this constant portraying as your opinion as being the accepted scientific standard, when the outlook of your written texts are anything but scientifically just, too unprecise to begin with...

 

[Kassiopeija]

Heat, efficiency in electricity, uv, ir....

oh yes these topics matter greatly, esp. UV sounds intriguing. Its like doing the Hps/Mh exvhange last 2 weeks.
Could you give me a breakdown how these do function, and recommend a good modern product?

SolarSystem® UVB

The latest generation high output UVB T5 fluorescent bulb. This system is perfect for a single light in a tent or several hundred lights in a large commercial operation.

I’d probably tan under them at about 36” at least

edit: seriously, I don’t want anyone reading this and trying it... don’t, it’s cancer causing.

edit2: also not sure why the title says standalone unit in a tent, not sure what for, not for cannabis.

I run two of these along with my HID. Note a quote from this article “In University of Maryland studies of indoor-grown cannabis, sativa with no UVB compared to plants provided with equatorial sun levels of 385 nm UVB had a 33 percent increase in THC levels”

I haven’t hooked up my new panel yet, did you get to do some runs with and without?

I’m on my first run with them. However, everything I read on UVB exposure points to higher potency and more trichomes. Definitely don’t want to be in the tent or working under them when they are running! They are strong lamps.

I have a shit quality led that i bought just simply for vegging plants, because the growth is slower and can be placed closer to plants.. so while my 1st tent is flowering for 8/9 weeks i have a second one with my new babys vegging at a slow pace ready to be thrown straight to flower when first is done. 600w hps in flower tent

Think about this issue differently. Newer, full spectrum white LEDs are relatively new.

If someone is a great veteran grower, they have been growing for long enough they had to grow before LED technology was any good.

So most every quality grower is what they are having used or still using HPS or similar.

Since grower "X" is so good with HPS, how long would an HPS grower need to match their skills in LED? 2 years? 5 years? Im sure X could grow it well the first time...but thats not the same as mastering LED.

As a wise man once said, why choose when you can have it all? Nobody is limited, everyone can choose and mix it up if they want.

As so many posts mentioned, climate and location and budget and scale all matter. On a small scale, does it really matter what the cost differences are?

I think the only truth is that HPS (and similar tech) growers have proven THEMSELVES to be great growers and they can prove HPS works great.

LED have many benefits. Saying they don't is being willfully ignorant or just belligerent.

Likewise suggesting pro HPS growers don't know sxxx is just plain stupid.

Kingrow may be a dick -- i donr know, just saw him post for the first time here. But a comment he made halfway through the thread that the GROWER matters, not the technology is the TRUTH.

Was just wondering what made you all decide to go with your lighting choice?

I'm pretty knowledgeable about electronics (10yrs working on them in the air force). I did a TON of research before I started growing back in June. Knowing what I do, I came to the conclusion that for me to be happy with LED I would either have to DIY or spend a crap ton of money. I was never interested in the blurples once I figured out the whole "1000W=200 actual watts" deal with them. So to me the easiest choice was to go with the tried and true old school HPS/MH so I could focus more on learning about how the plant grows instead of spending most of my time trying to get the perfect vpd, or be worried about whether I needed to add this red spectrum or that blue one.

I am running 2.6kW of HPS and at my current electric rate, that's about $115 a month. Way less than what I was paying for my weed.

So again I ask,
What made you all choose blurple/led over (what seems to be the easier way) of hps/mh?

And Merry Christmas too! Hope you all got some great new presents we will all see pics of in the grow rooms soon!

I went with LED a few years ago. I have a very limited space (2.5 feet deep by 5 feet wide by 5 feet tall). I have one Advanced Platinum P600 as the main light and two Advanced Platinum P150 lights to fill in the outer edges. My main concern was heat dissipation and I really didn't care about cost. I grow 2 plants at a time (DWC) and get 14-16 ounces of dried bud each time. It works for me and I'm glad I don't have to be concerned about the heat.

As a broke newbie to growing cannabis (I'm a full-time carer looking after my wife, so money is tight)
The first grow room was lit by modifying 3 tube 18w fluorescent ceiling units, to hold 9 tubes providing 162w . Three of these units lit 15sq ft 486w and that translates to 32w per sq ft. The yield from the first grow (ever) was 1oz a plant from feminised auto. My limited growroom height meant the downside of these lights was headspace, they took up so much space.
After much research, I decided to go to LED: There were three options: cool white, warm white or full spectrum. It made sense to me to go with full-spectrum. The strongest lamps available at the moment are 100w and 200w cob LEDs were either cool or warm light. 50w full spectrum COB LED seemed an ideal choice. My main concern was the power draw from the wall, was it actually 50w and it was, so these are really 50w LEDS.

My 50w cobs were sourced from two suppliers, five from one supplier and four from the other to see if there was a difference. Eight LEDs were used in my "lighting system" (link) 450w a slight reduction in my fluorescent setup but is seems much brighter. (eye-balling is a real scientific measure)
I'm tempted to add a few warm and cool white LEDs to widen the specrum. I'd also make it so the cool white could be turned off for flower.
The yield and quality will be the proof of the pudding.

There are really valid reasons for going with HPS and in hindsight, I could have used the heat in the winter.

I'm in the same boat bro. Snagged a LED box but found the winter house temps to be a bit low. I ended up throwing a 45w incandescent in the tent and that is keeping things proper.

Still learning....

I ended up ordering 1 of these last night to use in a 4'x4' final flowering area with a 1000w se hps. Plants will have the opportunity to be under them for last 4 weeks of flower if wanted. I'm interested to play around with it and see what it can do.

How big of an area are you running the 2 in and along with what other lights?

 

[TravisG13]

A lot of people shop on amazon and according to the reviews on amazon those blurples are great, learned the hard way myself but now thanks to reading into this forum and reading the reviews from actual growers and not bots on here it was pretty easy to make better choices on purchases.

Edit. Sorry that was my answer to the initial question I see it has moved on to UVB somehow... I just bought a single 4' t5 fixure just for UVB (from what I have read LED's don't provide great UV) in my tent which runs 4 hlg132's... Do you guys run your UVB all day and how high above the plants do you like to have it if its supplemental lighting?
