that, and you have to buy all that equipment, take up all that space, then act like a douche on the internet because you spent so much time and money trying to grow like the big boys.
Have any of you DIY COB Growers finished a crop under 1000W DE HPS? - POLL

Do you have anything to offer aside from conjecture and anecdotes? So you're not interested in(or capable of apparently) intellectual conversation.....You're just interested in proclaiming how right you are. Good to know....

whatever helps you with your inferior lighting and growing skills. remember, you're the one trying to compare to what I got.

You clearly have very little experience with the power of a high wattage HID Lamp.
You could put (10) 100w hps lamps in a 4x4 and you would be lucky to grow a 12" deep canopy with the lamps 12" above the plants.
Switch to the 1000W, move it up to 24-36" above the plants and grow a 24+" deep canopy across the entire grow space.
This is why cob has not taken hold in my opinion. No one has demonstrated that it is powerful enough to support 24-36" tall individual plants the way 95% of the industry actually grows.
Up here in northern cali you rarely hear growers talk about scrog

We compare output in reference to HPS because it is old technology. When cars first came out they referred to their power as 'horse power'. At any point in history where a NEW idea/option it is introduced in terms of current usage. Once adoption takes hold, references change.
Even then years ago I remember HPS being talked about in terms of sunlight
if we compare COB lighting and HPS in terms of real sunlight we aren't comparing to YOUR light and still having the same convo.We reference in relation to YOUR light for your benefit and in relation to the OP's question. Go to the LED forum, the language is very seldom in terms of HPS unless someone asks for it

KAY, so it's been fun pissing you guys off. See ya in about another year when i come back and play with you,AGAIN.LMFAO
here is your chance to personally attack me without me returning volley,ready,GO,,,,,

There are a few real high power COBs.
The CLU550 from Citiled recently got updated and is more efficient than HPS at it's typical current rating which is 2.34A which translates to 243 watts and it's max power goes up to 595 watts.
This all from a chip that's barely larger than a vero 29.
Flip Chip Opto has a 2400 watt chip but is certainly less efficient than HPS when driven that hard.
So there are COBs as powerful as HPS, and some are much more powerful than a typical HPS.
Also the problem with 100 watt HPS lights is that HPS benefits from a higher wattage in terms of efficiency.
A 100 watt HPS is far less efficient than a 1000 watt HPS.

Well there IS one; lack of UV. Yet dozens of test grows have shown healthy plants with absolutely no shortage of frost.
The upside is that a new generation of growers working under them will never have to worry about macular degeneration like they do from all current light bulbs from HPS to CDM and including all forms of induction and florescent lighting.

Yes he has and so have I and you need to try it the other way before rendering your arbitrary opinion.

You do know they make narrow angle reflectors and lenses to focus the light. Specifically for high mounting applications. It's simply a matter of matching up components. Though you are right, I haven't really seen anyone using narrow angle optics yet.
Hmm, I wonder what's readily available now that I'm thinking about it...

ive already discussed how inefficient small hps bulbs are
cob is plenty powerful to support 24-36" plants
hell my blurple rig is 30" above the plants - 14 170W fixtures (75 par W each) in 5x9. it is 800 ppf *uniform* at the top of canopy and only 600 another 18" down. ive stripped the bottoms but the good stuff is a solid 18+" deep
i think in this case you are assuming plants are closer because light is *weaker* and they need to be closer.
1000 W of COBs are actually significantly *brighter* than 1000W of HID and at 24" height it is perfect coverage AND good depth esp when spread out in an array

You hate LED so much...but use an indagro. Then stumble on a 1000w hps and shit your pants and what 35-40% efficiency is. Welcome to light bro. You could have more with led but you are stuck in un founded claims like you just spewed. Light is cumulative..2+2 does in fact=4. There is only "x" possible amount of possible carbon to be fixated based on light available. There is no such thing as "more powerful light" All light moves at the speed of light, not matter where the fuck they came from(LED, HPS, or a damn supernova light years away). Imagine that, the speed of light.
If you need "deeper penetration"....more scientifically known as enough left after transmittance to continue to produce sufficient lower growth development..then use a higher PPFD that correlates to the growth size. Using 500 PPFD(shitty leds or too budgeted on DIY) to grow a 6ft plant is dumb and we all know it. Do a real and quantifiable experiment and it's clear that lights is light.
Real results...from commercial and boutique MMJ growers...in Norcal and Socal since that apparently matters. Learn the difference between using a trellis and a SCROG dude.
Pacific Light Concepts cx300(cxb3070's) with an average PPFD of 850 µmols/m2/sec
CXA 3070 and CXB 3070 with an average PPFD of 919 µmols/m2/sec
An average PPFD of 781µmols/m2/sec

Gavitas aren't really Ferraris.... More like a VW CC with turbo
Well engineered, on the cheaper side, dependable, large following but nowhere near as nice or fun as aTesla.
You can buy Apple or Google now, but if you bought them decades ago you would be much better off
There's a reason that all products have a life cycle. Some are early adopters, some people still use 8 tracks
