1000W of DIY cxb driven to be 50% efficiency 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.

what light are you using? what led would you recommend to a person who can not diy? i am currently running testing on ceramic discharge vs hps/mh so far it looks like the ceramics are more efficient in terms of yield per watt. if i can find a decently,, not over priced led to cover a 4ftx6ft table i would really like to ad it to my test..,
i have only run 2 315 watt cmh once,(but i now understand how the plants respond to cmh so further runs will only get better) im currently about to start my second run under 3 315 watt cmh 945 watt total over the 4x6 table, next run will be under a 1k hps,
i think a reliable testing of led is well overdue. or a non biased test.. i keep everything exept lighting the same so that results are true,non negotiable..
my first try with cmh yielded 800 grams dry trimmed n weighed off only 630 watts, i plan to re do that run in the future with a longer veg period as plants do not stretch nearly as much as they do under hps or hps/mh.. had i vegged longer i believe i could have yielded 900-1,000 grams but we will see.?
i wish i could rent a good led as i already have so many unused lamps, or buy one and return it after 8 weeks if it does not yield like hps or cmh..please give me a list of led options you believe will cover the area.. i also wonder if multiple led's rather than 1 large led will get a better yield per watt, as ive found with hps/mh running 2 600's or 3 400's seem to yield better than a 1k over the same area as you can place them closer to the canopy..my real goal is to find the best yield per watt lamp as my electric bills wer truly outrageous.. i can say that going from 2 600 watt hps to 2 cmh cut my bill in half and yield was very reasonable considering the drop from 1200-630 watts..

If you can't DIY right now stick with the CMH, forilla.

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.

lol wow really i do not use AC never have EVER even in 6 k rooms HID NEVER so lets be safe to say what 1000 bucks to make 1000 watt cob you know shipping odds n ends etc lol let me see here i can purchase brand new 1000 hids Mag ballasts hood and bulb for 150 bucks holy shit that just gave me 6000 watts for the price of one cob 1000 watt equivalent were not even in the same fucking league if you break it down to a science that is
you mention look at Realstyles grow trust me i have lol and what shitty grow small buds and most importantly small plants and again small stalks with heat issues haha kind of ironic really when that is the selling point of cob so much cooler , but hey RS is a grow god do you not know him ?? he is the guy that talks like a fruitcake and grows in a fucking tent you know when you really look at his video's and he grabs some buds there the size of your fucking thumb and he goes around other sites pretending that he is a diy god of cob taking green genes , spl and who ever elses hard work and sluffing it off as he was the one that teached them lol i am a grow god just ask SPL lol WTF

No sir maybe once it becomes legal here in canada i probably will until then one must grow undercover ,, who knows maybe do green house grows one its legal and instead of 1 - 5 plant tree grows maybe 100 - 200 tree grows :)
But what does having a Tube channel got to do with growing weed is it to make your self look better or try to sell something ? lol
i mean really shit go search Dr Fever on this site if you still can that was my other name i have some pretty big grows journals i was doing on this site well before the legaliztion of MJ in USA many people will in fact back me up and yes did stupid illegal grows you know them ones with over 700 plants in all stages 700 clones and in all stages
But today from the legalization you got the crawling out of ever rock now huh
spineless really no balls to be known when it was illegal but now Guru's when its legal rings hollow
have played with more soil then most growers will in a life time let alone probably thrown away more clones then most will ever grow ,, you know when you get approched to make 300,000 clones for 200,000 dollars brings anyone into a new league all together ..
even thou i passed on it still was offered to .. but then again these people will bury you and your family in a second if something went south so again big money lure or breathing which would you choose

Yo testicle you want to know what 22 oz's looks like real world not fairy tale Land here one screen square half of this door screen is anywhere from 18 - 22 oz dry 3 times more then that picture above lol who is weasel now
See i got nothing to prove here but it appears COB does Hids prove them selfs over n over n over shit look at this grow lol old bulbs used 2 year old grown bulb still kicked ass so please keep growing with your what ???? 150 watt panels and keep talking like your a grower dude seriously in the gaming world you be called a SCRUB but hey in the growing world lets just say you been schooled dscf3918v.jpg

Whats a smart car?

Those little piece of shit 2 seaters with a 1.5 liter engine. Made by mercedes. That can't handle a basic turn.above 20 MPH and climb hills. They're popular in europe. Years ago when I worked from a reprographics company, my boss had one.

The only thing smart about them is their fuel efficiency. They have a very small gas tank.

They're no where as smart as prius or a tesla lol

They don't look very safe. I have a car. Not sure if its considered a smart car. But you do plug it in. And it also has a gas tank. Actually we've only put 18 dollars of fuel in it in the 6 months we have owned it.

No they're not. They flip over easier than suzuki sidekick. They would be crushed like a a soda can in an accident.

The safest cars are Volvo, Saab, and Mercedes. Each of those you won't even feel it if you blow out a tire. Yes I have experienced that in a Volvo s60 and a mercedes e 350. One time driving back from AZ and another driving back from Vegas.

You dissed RS for his youtube videos, and then talk about how a youtube channel doesn't matter. You're talking out of both sides of your mouth again.

I never claimed to be anything I'm not. But I am smart, and that counts for something. I'm also kind, which means I'll end up with more allies than you will, because you're not a very nice person.

If I'm "green behind the ears" then you're "wet with envy."
OK, Ricky, I'm going to go ahead and ignore you now.
