I know I just pulled down 2 1/2 # from my 1000 watt DE....first time also.
5x6 canopy,11 plants in 3 gal pots.

How much will a 1000 watt of cob cost? To cover that same 5x6..

It will cost me about a grand to cover 4x4 but I'll run less than half the wattage, and they will run for years and years. I am sure to pull 2lb from that without much trouble. No one said they were cheap. Yet. Time and data will prove all this stuff. 1000W of efficiently-powered COB would cost around $2k and you could cover 4x8 without issue, you could rock 4x12 with 1200W

I'm not worried about running something for years upon years....I run my hps bulbs for 18 months, befor I think about changing them..

So how much to cover a 5x6,and still get 2 1/2# ....plug & play setup.

5x6 is 30 sq foot, so about $800-1000 to get everything depending if you need tap and die and a drill press or if you own them already. I'll bet no AC would be needed, just venting to an external space or outside.

I don't use actually now...2 regular hps 1000watt & 1 DE 1000watt. Just exhaust fan.

All of that in a open room,do the cobs need to be in a more confined space?

Not as far as I understand it. I have designed my lights but I haven't built them, shooting for January 2016 due to prior commitments. Anything I say about this is based on evidence from that list of growers I posted when I bitched out Darth Vapour :D They are amassing some good information, in between arguing about this with the Gavita-lovers, haha.

No lights at all need to be in a confined space. Light is light. If you don't have enough coverage , add more light.

It's about 12 cxb 3070 , vero 29 or 8-9 cxb 3590 per 4x4. To match a 1000w basically around 650-700w of cobs.

I'm modifying one of my lights to replace some cxa's with some cxb 3070's. Soon more cobs to come.

What truth bro? So you think I'm lying about Cree stock or you think Crees a bad investment? Just trust me on the stock being around 40 this time nest year. Please don't listen to your boy about this stuff. Ive made a few good buys over the years. And yes some not so good ones. But its a game i like to fuck around with. Heres the last 2 days of cree. @hyroot has no idea what i bought the stock for, he's just sandbagging me calling me a liar about not owning cree stock. I shouldn't of said that stuff about his garden, i know that. My bad. Just sounded cocky the way he came off in that post thats all.

I am a Cree INC stockholder as well. I am a little bit concerned about the stock's future due to the separation of their Power & RF into a separate entity called Wolfspeed. It could be an exciting IPO to get into, but I don't what that does to the parent company. Taking revenue generating technology out of Cree INC and moving it to a new company. ?

1000W of DIY cxb driven to be 50% efficient would be a good amount of light for a 5'x6'. That would be 500W of PAR (50% efficiency) over 30sqft, so 16.667W/sqft PAR so you'd be able to flower 3-4 foot plants.

I'm still not sure if it's worth upgrading from HPS for you yet, but it's good to have options on the table. I yielded over 300g on my last C99 grow from a 193W lamp in a 8sqft. If you scaled that up by 4x, that would be 1200g (2.679lb) from a 772W lamp in 32sqft.

On the subject of stocks. Ferrari went public on Wed. Opened at $60 a share.

I'm a huge ferrari fan / formula one fan. Ever since my dad had a yellow 1981 308 GTS (magnum pi) when I was a little kid.

Leds may work, but I chose HPS since it's been proven to work and commercial grower's use em though I may try leds when they're used more widely with results from professional growers who aren't paid to say they work as well or better than HPS.

^^^ if only a L.E.D that worked like that car could be bought from a dealer, but we all know it would be the same price as that car.
