The way LED technology vs HPS technology is progressing, Its a no contest which one is going to come out on top in the near future.

Because we run both, you know that. You really think we are here just playing. Like we don't have QB and cob grows going on with DE too along with SE hps?

no, I don't know that. I don't sit here and read what the whole forum is doing, But yea I do think that is the case. That's pretty much this whole forums M.O.

Well you seem to view these LEDs in a somewhat negative light. And you said you didnt think your QBs would even come close to your HPS light they replaced. But that's on you. Not the LEDs. When newbies are pulling over 1.6 grams per watt quite often their first or second grow, any experienced grower should be more than able to as well. If you can't, dont blame the LEDs!!!!
MOST people I know who swapped from HPS to diy LED love the LEDs way more. And I cant blame them...
I mean if you didnt think your temps needed to be higher (80-85f) then it wouldn't surprise me if you didnt perform as well as your HPS grow... HPS grows stretchy plants, pumps off heat, and the leaves/structure of the plants differ a lot from these white LEDs. Stuff you need to adapt to.

I would not call it hypocritical - its just short sighted. Its like the guy that passes on the 30 mpg car in favor of the 25 mpg model that's $1000 cheaper, when he's going to be driving 3000 miles a month..Yeah no biggie
I just hope HPS growers recognize how quickly you can pay to upgrade to LEDs simply in electricity cost savings. My 350w (draw) led setup is very close in PPF/ppfd of a 600w hps, but I am saving $200 a year in electricity by using the LEDs. That's a lot of money, and considering HPS growers complain of the upfront cost of these LEDs, they need to realize how hypocritical that is .

I don't think your boy has ever grown with HPS. Thats the sad thing. Dudes the biggest troll on the internet right now.

Have you seen your plant you have growing right now? Your having trouble getting 1 plant right.

Yep. And LED technology is ahead where we thought it would be now a few years ago. Here is a .gov picture estimating the avg. efficacy of LEDs. I mean I see a LOT of buildings/hospitals/etc. have upgraded to super efficient LEDs (literally like the samsung strips, they actually are used in lighting fixtures and not just grow tents haha). And of course the LEDs we grow with are going over 200 lumens per watt now. Not a single other lighting technology is improving at the same rate, and will only fall further and further behind.
lol i don't if this led grow fucks up ill decapitated

Lol what are you smoking dude. My plant is fine. It started to get hungry a few days ago so I fed nutrients for the first time. And it was a bit too much. First time using this nutrient line, been using GH for years and swapped to nectar which is a totally different kind of nutrient line. It grew 3 inches in the last day and a half, and it's in soil. So it's definitely doing fine, just a finnicky strain.
My plants are almost always healthy as fuck. And I pull even healthier yields.... Ever see someone pull 500 grams from 420 watts of chinese blurples? Probably not.
Again, i dont want to argue with you. I was correcting the misinformation you provided.

My plants look exactly like his under my 600 watt hps. I would see no reason to change other than curiosity. Which I am. I really want to do a side by side.
skoomd, what would I need in my 4 x 4 to do a comparison? Lets stay around 600 watts. (you say I can get the same results with less tho) I'm already buying the new Hortilux 600 watt cmh to try out and I want something else. This will be a 3 way comparison. Since you seem to be the guy who knows what's needed for a specific area I would like to get your idea on coverage for my 4 x 4. I don't need to build it myself. I'll buy a prebuilt system. Then I can see for myself what does what. What do you say?

Hlg 550 or hlg600 or a cob kit. Personally I'd go with the hlg 600

Yeah it does work. That's why everyone has been using HPS to grow since the 80's. And that's also why long time HPS users, who went through the LED scams/lies/false promises over the last 6-8 years, have such a hard time giving up their HPS lights. They've been told for many years now that LEDs would replace it with half the watts. But it hasnt been until very recently that that is ACTUALLY the case nowadays.
When LEDs were first commercialized in 1996, the efficacy of a white LED was about 5 lumens per watt. High end white LEDs today in 2018 are hitting 221 lumens per watt, with an average of about 150-160 (getting up closer to 170 now). And just 4 years ago, high end white leds maxed out around 180 lumens/w (81% of today) and averaged 120-135 lumens/w (85% of today).
So in the last 4 years, high end white LEDs have gotten about 20-25% more efficient. And WAY cheaper. The average $ per PAR watt for the CXA3070 was about $2-3/par watt. Samsung f series strips run you about $0.70/par watt.
Well my friend runs 600w of samsung f series strips in a 4x4 tent and he just pulled 1050 grams dried. I built him that light for a little over $500. That would be an excellent light for a 4x4 tent, you'll max out the intensity. Easily will replace a 1000w HPS in fact. A 1000w HPS outputs about 1300PPF (minus 15-20% of that that is lost in the hood) and his 600w strip build outputs 1440PPF.
But if you need a prebuilt option, the HLG 600h kit is the way to go. It's essentially the same as my friend's build, same diodes, similar coverage, same wattage. It's $700 prebuilt+tested.
Though to replace a 600w HPS, a 400w COB build from timbergrowlights would be plenty to do the job.
Expect to be blown away. I would love to see you post your results on here, if possible.
