I have a 4x8 flower area with one 4x4 area using 1000W HPS and the other side is 16, 3590 COBs. The plants on the edge of the 4x4 HPS area are all leaning towards the COBs. They love them.
Going from HPS to LED. Worth it?

How many watts total for those COBs and drivers? If I did that I'd be at 900W, 4 COB LED on each of 4 modules pulling 225W.

Are you sure about the 50% thing man. I've ran many different lights in the led range your not gonna get fifty percent more unless the strain your running yields high. Really you can only claim this if you've ran the exact same strain with the exact same setup minus using an LED. I've seriously ran most of the big names including building my own you don't get fifty percent more. What you get are some better numbers IF your dialed in on your grow so say your running a thousand watt hood and drop to about 700ish watts. You then can avg either the same as or a bit better than it's hid counterpart. You will get however lower room temps, and the spectrums that your plants need. No more wasting energy one bs spectrums the plants can't use. The folks that say" holy shit dude I got way more than last grow" are either full of shit or grew a different strain or ran bigger pots. You don't just magically get more for less. These sort of statements are what make most others disappointed once they switch because they all of a sudden think they'll be some sort of super grower. I love LEDs I grow only with them however ppl spreading this I only pull 300 watts from the wall with my mars LED getting 50% more than hids are horse shit. Let's make realistic claims here guys maybe then the hid guys might take our Christmas tree light panels seriously lol.
I have grown for about the last 5 years under led, so would say I have experience growing under led. I also have used hps, lec and various halides.
Here's what I think about this 50% more efficient. People imagine their full room of donkey dick buds under there 600w hps, then try and imagine half more buds again. Those people will struggle to see how led is better than hps as that will seem like bullshit! Then you get people that digest the concept of using leds slightly different from than others
It can do the same donkey dick grow, but with about 50% less electric being used.
Btw 50% less must be a grower with the best cobs totally dialled in with their shit together big time! 50% is ambitious imo, especially looking at matey's gavita grow. Pukka grow btw!
I have mental health problems and am going back to 100% led to increase my general health and well being. With hps, I hate the heat, I hate the loud fans, I hate the extra anxiety of there being increased fire risks. I also hate the dry look the leaves gets coz the extraction is on so much, the humidity gets sucked out of there too fast and it lowers the rh too much.
Don't forget, especially for you guys and girls in the USA. Some of you have ditched air con during the switch... Now there's some savings for you that will piss on the 50% figures. Switching off a 2kw air conditioner and a 1000w hps to plug in 600w of cob
Then there is the quality, led grows great bud, like cmh/lec does, hps, even dual spec is good weed, but lacking in the potency that a full spectrum white light gives it. Many growers switch from hps to metal halide for the last few weeks to increase quality. That says it all.
I find led buds are smaller, but more dense. So you grow more tops, veg out 50% tops if you switch to 100% led.

Speaking from experience, you guys need to skip LED panels and go straight to COBs. Those are the real HPS killers. I can see a huge, huge difference between two ViparSpectra V450s vs. One 89w Tasty T1 fixture with top bin Cree CXB 3590 emitter and 2150mA Meanwell driver. Just one COB blows both "450w" (206w) panels away.

50w per. It's a perpetual grow. The first round of plants went under the HPS 6 weeks ago. But since I had 400wCOB already built I also put one plant under that light. That plant took 9 weeks and a few days the last time I grew it under HPS. She is now ready to be trimmed at 52 days. So it finished almost 2 weeks sooner under the COB.

You won't need anywhere near 1k to achieve the same PPFD given off by 1kW of HPS.Dare to post threads where Cob is killing Hid here 1 plant 1 k holy smokes Eh

You're a decent grower. What makes you think you can't do that with cobs? Maybe pack a bit more weight on with better light spreadDare to post threads where Cob is killing Hid here 1 plant 1 k holy smokes Eh

Yea yea still waiting for LED to come even close or even 2.7 GPW from Cob i mean shit Cobs been out now 3 years and what ?? here 1 plant
1 k But personally i would not run any LED out in the market there all garbage if anything i would run Cob well before purple lighting

Dude im just quoting the led growers, no ifs and buts. Either they yeild more or they dont, if there is no straight answer i think ill hold of on them 3watt diodes till things are a little more clearer.
Who said us British dont have a dry sense of humour

i am not fighting back , lot more then just light people see one way and that is it be it efficient or spectrum's or what ever
Truth is its disappointment after disappointment..
Remember its not hid saying there LED killlers its the other way around its LED saying there hid killers
King would love to see least one picture of your grows with this 600 LED that claims to kill a DE unit.. i can show you i plant harvests from De

COBs were invented specifically to replace HPS in high bay/low bay industrial applications. Better light, negligible heat, for less energy. 89w and I'm putting out PPFD equivalent to 500w (between 400-600w) of Super HPS in a smaller area.
89w for ~850 PPFD in a 2x2. I have a second one, and two plants for a 4x2 closet.
There are always different options with led to compare the 2 lights. Say you run a 5ft x 5ft tent with 1 x 1000w hps. Instead of having 1 x 1000w hps in one 5ft x5 ft tent ----- run two 5ft x 5ft tent with a 500w led in each, instead of using 2 500w leds to replace 1000w.
I think a 1000w would yield more in the same area as 2 x 500w cob leds
However, I think the running 2 set up's with 500w in each would outyield the 1000w hps by quite a bit!
That's only my opinion though... I'm sure some will disagree.

we no they weren't they were invented for actual lighting or replacement of street lamps door way lamps and such sure there brighter but again what plants use are different then what we see we might as well start talking lumens oh wait a minute Cobs do

Do your seedlings and veg'ing plants grow trichomes as early as day 3 in seedling? Because mine do.
