All BS set aside CMH yields

[ttystikk]

Cob led is out of most peoples reach...just for the simple fact...we want to grow buds NOW...not dick with sourcing and building out a fancy grow light. Its definitely NOT the first choice for most growers in 2016. Thats my reason anyways. Sounds like a big pain in the ass to be honest. I will wait until they are commercially available at a price i can afford. I started to delve into the whole cob thing and quickly (smart too) backed off. A large majority of growers are thinking like this too. We all know its the mostest and bestest light but ya gotta find the info...source the parts...and build the goddamn thing yourself. Its a whole another geeky hobby if you ask me. And i already got one of those...growing dope.

Responding to a different part of your point, I outsourced the building of my lights. It worked for me, in part because I made a sizeable order worth someone's time to assemble and deliver.

I'm glad I did it because I learned a lot about the process and the lights have made a very significant difference in the quantity AND the quality of the resulting product.

Just found out that the Sun Systems Grow Beast fixture was designed with the popular 4x8 area or table in mind. And with a 6 foot light rail moving just a little back and forth so all canopy gets the mix of lec and hps de. Iam seriously thinking about getting the whole setup as an experiment aside from my regualr operation. The usual setup with a 4x8 area or table is 2 1000 watters (single ended) or 3 600 watters (single as well). The Grow Beast is just 1230 total...a 315 lec on each side with a 600 watt hps de in the middle (you can put a full on 1000 hps de in there but you would need to raise the fixture so high as to render the lec lamps damn near useless. ) But anyways...iam gonna try it here soon. If i can get 1800 to 2000 watt single ended yields ( 3 to 4 pounds) from 1230 watts of de and lec combined its a no brainer. And the hype is justified with lec and hps de together for state of the art cutting edge lighting. And besides...been wanting to upgrade my tester room. And this would be perfect.

So here's your challenge; I've pulled 2lbs from a 4x6' trellis, with only 900W of COB LED.

To match density of production, you'll need 2.67lb from your 4x8' table, to match Watts/sq ft you'll need 1200W. I think these are very attainable numbers.

Except that I did it with only 6 sq ft of floor space.

Here's the flaw in your logic;

2016 IS OVER.

Any of a number of different sources are selling COB LED right here on RIU in kit form, all you do is assemble the parts, and in so doing save a bundle. Having to source all your own shit is the part that's sooooo 2016.

Can you point to any of these quality builds because I too don't have the time to delve into another hobby and learning a new skill set at this very time. But id love to supplement my CMHs and DEs with some LED and have the ultimate room and spectrum.

Iam hip. What and where are these kits? Tools you need if any? Id love to try em out...but iam not getting all involved in schematics and diy buildouts. Dont get me wrong...i like to see less of an electric bill just like the next grower....but i dipped my toe into the forum cob world...for just long enough to get it out and run away. All this talk about bins and heat sinks and percentages and...good god man. The price of dope is falling but i still make good money. Iam fine with double ended and lec lamps for now. Until i see these fancy cobs in the store for 500 or less...i will let yall build away. I dont have the time nor the inclination to build a frikin grow light. I dont care how bad ass they are. I mean...really...are they THAT much better than a couple de 's and a couple lec's you can buy anywhere and slap them up and be growing in hours? I will wait till the stores stock them like all the other lamps.

Yep same here. I work part time and go to school for my doctorate and masters simultaneously. Growing is paying my 210k in school loans so that I can live a legal and frugal life when I get out.

Ok...heres my challenge..What kit or kits do i need to replace 4 of my Gavita 6/750 flex lamps that i can pull 24 zips of Blue Dream off of the 600 setting on each lamp (and thats a lazy same as it ever was grow). Whats the real world wattage...and how much ac do i need to keep ky canopy around 80 degrees? See what iam saying tty? This is the majority of growers line of thinking. They dont want to get into all that jazz you guys talk in the cob threads. Just simple and to the point. Because everything else just goes over thier heads. It does mine. Seems you have to want to or have a real passion to get into the diy cob world. Most growers could care less and just want the lamp the grows the best and most buds for the least amount of electric bill doing it. All them charts and links and part numbers and percentages of efficiency and all of it....just eludes me.

Have you tried anything else besides gavita? I'm new to DEs and am ready to supplement my LEC room with some. I like to pay the up front cost and just get the best there is. Buds pay for lights in 10 weeks lol. I have friends that only use phantoms.

 

[ganja361]

I own 22 of the phantom DE's. A few of the enclosed, but mostly the open ended ones. 4'x6' footprint(awesome if you grow in trays like i do) for each open ended fixture, and 5'x5'ish for the enclosed.
Cool thing about these phantoms is you can run the ballast remotely. I do that in a few of my rooms where i only have 8' ceilings.
Only problem i've had with these phantoms, is that after 1.5 yrs with them, i've had 6 of the ballasts die . Three year warranty, but it still sucks.
The sunAgro bulbs that come with the complete phantom DE setups perform just as well as ushio bulbs that I bought for some of them

Thank you. I'll of course do some of my own research but nothing helps like personal reviews and experience.

 

[thccbdhealth]

I too have been looking at cobs and learningthe configurations but have been reluctant to order components
i was going to grab a 315 but have herd it may not be enough light for my 4x4
and i have herd a 630 (2-315's) would cause to much heat and too much light in a 4x4

So now im wondering what's my best bet
im in Canada and having difficulty finding sources for either within canada cob and cmh

Tactically if your going vert. Drop a naked 315 in the center of 4 plants. Use all the bulb and get a bumper crop. If your gonna Scrogg do two plants and get a cob and still get a bumper crop... I'm biased to the first option but style will weigh heavy on this decision. You won't loose either way. As many opinions are out and both techs are solid. Both will get you great meds both have an entry and learning curve and with that space allotment your style may be predicated on budget. I've seen the cob stuff do some pretty amazing things and like a lot of the old timers still a little hesitant to pick up the new hammer... happy growing..

No. But if I had to do it all over again...i would of went with Nanolux. Just for the orientation of the ballast. On my Gavitas i rarely use anything past the 600 setting (Nanolux de only goes to 650 tops I believe) anywAys. Iam working with a 78 inch tall basement. Which is kinda low for any double ended hps but the sixers work out fine. The thousand watters are just too much light. I could dial them down of course but the spectrum isnt ideal when a double ended thousand is dialed down. Hence why Gavita came out with the 6/750 flex.

In the local hydro shop i could get the gavita 6/750 flex but how Could that be the best option For my 6'6" 4x4

Could you point me in the direction of fixture that would allow for that vertical garden - i was tossing back and forth between the nanolux and the sunsystem, both are vertically hung bulbs but are both in open hoods..
Nanolux use's their own ballast
SunSystem use's the ballast designed by Philip's if im not mistaken...
i was going with nanolux as its cheeper however i was advised to go with SunSystem as its philips ballast-
and ill be running the Phillips bulb either way..
a naked vertical application would be great, im wondering now what that raidious would be from bulb to plants?, Make a cage out of chicken wire to hold plants back off bulb?

Im inclined to try both methods; i can already see watering under this trellis net may become painful, its bad enough haveing to have the plants on the floor, but from what I've read and im dyslexic, guys are saying the net is the way to fill out this 4x4

I think I'd rather have full acess to the plants, could pull them out and onto a table if need be,
maybe Vertically is better suited to me

this would then give me 4 times the space to fill? Im new, but im thinking my needs will leave me aiming for a pound per harvest.

Get a 25 ft cord set.. gives more options for ballast placement...
Mogul adapter ...
3100k Phillips ... the one they sold me was open rated so specify... I learned to check..
Plug and play....

Its not the best option if its the only lamp. A good one but Gavitas and the rest of the attached ballast double ended fixtures were meant for commercial grows....using multiples of them. The overlapping and crosslighting is where they excel. And why the ballast is attached and orientated the way it is...less shadow and easier to maintain in a greenhouse...when you have to install and service hundreds of them. In your situation and most home hobby grows i would go with a thousand watt air cooled regular lamp...a couple lec 's from Sun Systems or a 600 watt double ended with remote ballast and hobby type reflector....but i forewarn you....even just one or two of these get HOT. Really hot. And you can be assured yiur going to need supplemental air conditioning...even if yiu think you dont because its winter right now. If yiu plan on growing indoors in a small space...with double ended lamps 365 days a year...plan on installing some kind of air conditioning. Thats why single ended hid lamps with air cooled hoods still have a purpose. Ive seen kids cramming double ended lamps in tents with no a.c. and honestly i dont know how they do it. I do know why though. They "hear" its the best lamp out there and thats only true for some situations. Double ended lamps with attached ballasts are truly meant for commercial applications...high ceilings...and in high numbers. Remote ballast ones (like the giant air cooled hood trend just a couple years ago) is just the hobby industry catering to what hobby home growers think they need.

 

[thccbdhealth]

Growershouse. Com ship to canada from my look threw their checkout process, says available for in store pickup

Thanks guys-no gavita for this tent indeed.
i have a/c in my house... house sits @21 ambiant in winter

I've emailed the company and it won't fit in any current CMH fixtures so it was a no go for me.

I have a 1000 Avenger DE fixture. All the research I have done shows it will work in it. I just have to dial my Galaxy ballast back to 600.

I have three of them, i posted about them just a few pages back.
My light meter shows them to be just as bright as my sunlight 630's.
Just fired them up a couple weeks ago, so I don't have a complete review yet. So far so good though

Thanks for the info Aero. I have been considering two 315s but am not into spending that much money right now. So a 140 buck bulb swap seems the way to go.
