100m x 100m is 10000 LEDs. you want a greenhouseLets say for a hundred LEDs (100mx100m) with good spectrum.How big would off grid solar would have to be?
Thanks

I am thinking if one led panel covers a square meter... Thanks
And how it works for you? Its the problem cause I will be needing 100 of those for 100 square meters.. Thanks

100m x 100m is still 10000 LEDs, I think you mean 10m x 10m = 100 LEDs
to get ~700ppfd for good efficiency, you need about 15 PARW/sq ft or about 165 parW/meter
to do that with 1 LED youre probably at 40% system efficiency so youd need a single 420W cob/meter
if you put 4 cobs per square meter you can get 50% system efficiency and youd need ~340W (4 85W cobs)
for 100 sq meters thats 34KW (not considering AC load, likely substantial).
assuming if you installed solar panels and got an average of 6 hours per day of sun (generous) and had 10% battery losses, that would be a 75KW solar array
average cost of solar array installed in US is ~$3/W, so $200-$250K
the cob array can be done for ~$1/Watt if you DIY or $1.50/Watt to buy it plug and play so $34K-50K
your 10x10m should yield about 120 lb or 55 kg every 3 mos including 4 wks of veg so you do the math from there
following the rule of thumb of cutting the current in half increases system efficiency by 10%, if you spent an extra $20-25K to double up the chips on your cob rig to get 55% system efficiency, youd reduce your solar array to 68KW which would save you $21K in solar array cost

Damn 4 pages and this guy has no answer, just an argument to stick with HPS?
I had quad 600's running over 2x 4x8's.. Vented hoods and yeah, its still hot and needed AC.
Sold em. Switched to luminus cxm22 x4 on hlg-185a-1200's. Simple aluminum rail build, active cooling was a bit more wiring, but cheapest option and best cooling dynamic.. Figure $200 each or so.
I run eight of those over the tables now.
HPS was about 3200-3600watts with ac and blowers.. (TWO Full 20 amp breakers)
LED is running at about 2200watts.. NO MORE AC!
Yield and quality are both WAY UP. Much better environment to grow in. ROI on those lights was probable under 2 crops. No more bulb changes is nice.. No more hood cleaning.. Time and money saved all over the place.

Can you e-mail me rjack5832gmailcom, and explain how to assamble cob/meter to get a good light. And I have few more questions.. Thank you man..

Good point, but why run an 18/6 light cycle? The only reason that I can think of is that you are running autos, and that is the reason I won't plant them. Too much energy wasted on a sub-par plant. I use an 11 hours on/13 off cycle to save electricity, with no discernible affect on product.

How many plants are you going to run?Hello guys! So I have 10x7 ft room with 6 (hps-600w) lamps and I am thinking to switch myself to LED because of electricity.
Whats it the best option for LED?
Whats the best option for LED in the terms of efficiency? What is the best substitute for HPS? Whats to you think about Hans Panels?
Thank you all so much.
That is a very large area, which can hold a lot of plants. Do you need that many plants, because if you want to fill that area, you will need more than a few LED's, but if cost is no problem (u sell a lot?), and heat is a problem, you could go LED.
I have 1 room that I use HPS in (no heat issues), and 2 that I use LED's in where I would have issues with heat and placement, and with the HPS my plants produce 25% more yield.
Personally, I would focus on less plants and buy strains that are big producers, pull a couple of the existing HPS fixtures out of the equation, save the money on the electrical bill, and stay with what you have.
Good luck

I use 11/13 or 10/14 for flower and either 20/4 or 24/0 for veg. I veg for two months. 2 plants = 12-16 ounces. Definitely not subpar. I have never run autos.
You should veg if you want more product. No wasted energy in more weight. 11/13, you're running a plant straight into a flower cycle without veg'ing it. 11/13 from seed probably gets you 1-3 ounces per plant.

Yeah noticed now after reading whole thread. That's some commercial size operation you're planning.And how it works for you? Its the problem cause I will be needing 100 of those for 100 square meters.. Thanks
25k watts that's some industrial electric you'll be needing tho.
Well coverage is around 0,9m2 one kit cost for me ~350eur +aluminum frame.
Could get it lower when going Citizen/Vero, haven't done any reading about them but I guess for flowering citi 1825 seems to be the best and they are driven harder aswell or vero 29.
Is there any shop in Europe that can assamble it? Cause I really dont know with my self? how to? What to look for? That a lot of pieces for me to go for the online order? If you are near Slovenia maybe You could show me? ThanksYeah noticed now after reading whole thread. That's some commercial size operation you're planning.

Too far sry 
but check out @Growmau5 from youtube. Got everything I need to know from his videos.
Start with this:
But as I chose at the time cree cxb 3590 I just had to send an order to KingBrite sayig "Hi I would like to order meanwell driver hlg-240-1400b, 5 pcs cree cxb 3590 3500k 36v, 5 ideal holders, 5 reflectors and reflector holders and 5 120mm pin fin heatsinks." Also asked them for screws and they nicely added them to order free of charge.
When parts arrive all you need to do is drill holes into frames(heatsinks are all perfectly pre-drilled),apply thermal paste on cob, screw them to heatsink and stick wire to holder.

There's nothing hard in putting them together. First you need to make a choice in what brand cobs to get. I think someone can give you a build for citizen lights.Is there any shop in Europe that can assamble it? Cause I really dont know with my self? how to? What to look for? That a lot of pieces for me to go for the online order? If you are near Slovenia maybe You could show me? Thanks

I have been growing with Cree cob CXB3070 ad for a while. I started to test this technology two years ago when was still unkown. After the first grow I realised that these cobs were even better than any other led or discharge lamp. I have a full grow room of 150 cxb diy. I use 450 cob watts/sqm and I yield 650 grams/sqm. Now I can smell the terpenes of my buds. I didn't had any heat problem anymore.
The problem is that diy needs a lot of knowledge, money and time (time is money). Now I'm using bloomingled panels because they are, in my opinion, the best cxb-based panel. It only uses meanwell drivers and cxb3070 top bin. The distribution of the light is perfect (this is soooo important). It is the same distribution I have been using at my flowering room (30cm between 50W cree cobs). Also I can control all the panels at once, so it's perfect.
You can check my grow diary also I can share my knowledge regard growing with cxb3070, just send me a pm.
They are totally worth. Don't be silly, you get what you paid for. You pay expensive, you get the best.

I just reviewed Bloomingled page,one panel is 675 eur, I need two for one sq/m and I have room 10mx10m you do the math.. to expensive.. only if you can hook me up for somewhere for lower price.. Is there any cheaper cxb based panel.. Hey man if you are from Spain anythings possible haha..

Having a hard time grasping why you would go from DIY to essentially the same thing w/ a housing & pot dimmer for x4 the $? Especially when they're only 160w a piece. No offense, it's just rare that you see someone go from DIY cobs to the same thing in a housing manufactured. If they offered something more then I could understand.

From their webpage you can only buy from Europe. I wrote them a mail and I bought them for $550 each, shipping included. You can try.
Dude, no offense but my time is too expensive. Growing is more profitable than doing DIY shits. I don't need a lot of watts of expensive LED fixtures, just a lot of CXB3070/CXB3590 for my grows. I don't care about any other LED color, 3000K is enough for me and my plants. Now I can start as many grows I want, yielding a loooot more than HPS... who cares about the initial cost? The panels get paid at first havest! It is ridicolous, this is weed bussiness. Grow big or go home
