Are cobs really worth it?

It's poor for 400W of consumption (sold as 4 x 200W!)... epiled "fake" cobs in action.. I used these lights 4 years ago.. I know them perfectly.

Actually its 330 watts on kill a watt meter.I have had this for three years and changed only one chip.I don't think that's so bad.I get 6 to 8 oz every 60 days from this rig.If you are a hobby grower like myself how efficient it is isn't important.Price and simplicity is.That make sense?

Thank you, my friend.

Soon, I hope. The wheels of Justice turn slowly...
I thought there was a case filed by a fairly big shot MMJ attorney for a sick boy about the plant counts.

Essentially the approach is that this re-regulation or re-criminalizaion of MMJ violates what voters voted for with the Constitutional amendment.

I know a commercial guy who is seems pretty middle of the road. he said Gov Chicicklooper or Hicklooperis a brwery owner so he is against MMJ.

Some have argued that - oh we need more regulations because people are exporting it and gangs into Neb and other states. IF we don't regulate it then the Feds will step in. F the Feds. States rights issue. Other states should be more worried about meth and doctors writing oxycontin scripts.

I lived in two states and knew of a doctor who was raking in huge $$$ in pain management. He was doing a political fundraiser at his $5 million house. This is in a state that just got medical.

I know Oregon is voting on legalizing meth, cocaine and heroin. I bet those douchebags still have plant limits for home growers. Sorry but meth and heroin are shit. There is nothing good about either one.

Those Chinese CObs you have - if they ever fail and you can solder - you could swap out those COBs for Citizens for about $9 a COB and it would kick ass.

Worse, there's evidence that more access to cannabis actually reduces use of hard drugs, and their consequences.

LOL.Yes I can and yes I will.Have you ever looked inside one of these?Their chips are driven by two drivers.Like it's actually two cobs on one die.each driver powers half the cob.I was gonna wait untill a driver failure to modify the light.
I have a single cob version of this light that I use to shine up into the plants that shit the bed last week.Ima relplace it with one of the new driverless leds.4500k 50watts(probablly more like 30)Three for 15 bucks.I can't resist the urge to try them.I understand some brands have a visible flicker,but I don't think the plants are gonna care.I'm also fairly sure they will fit the single cob fixture.

Run 3000K chips instead, your yield will thank you.

Insulate the room where the intake is, recirculate the exhaust, if supplementing with CO2, this will be of benefit as well, reducing the amount of CO2 needed. Of course a sealed room would probably better, then insulation becomes even more important because there are no heat losses due to ventilation. You're being pedantic man. It's really easy and you're arguing over semantics. 1k of power into an HPS and LED, one will convert more energy into heat the other will convert more energy into light. There's no need to get so worked up about it and arguing about cans, ifs, buts or maybes. It's fact. The point you made about CMH was great, different setups are suited to different contexts, there's no one answer. But to say that leds are inferior to another type of lighting, as Dick Rivia was suggesting, is also just simply wrong.
I haven't got worked up about anything?

It was yourself that began to get a little more technical claiming your an architect. I think your statement that 1000w of LED and 1000w of HPS is a little one sided given the amount of variables there are on each side of the wall, but I really don't think I was being pedantic about anything. Realistic maybe, but not pedantic.

Pretty sure I haven't said that LED's are inferior either?

As i have said I like LED technology, I just try to be genuine about its applications and abilities.

Honestly I'd rather use 550-600W in that space. A dozen COB LED chips, Citizen is currently the better buy for the performance.

Another option is 550-600W of Quantum Boards. Similar performance, better light distribution.
I agree but the whole issue is cost, I'm not in a legal state and can't afford to drop s bunch of money cause it's a hobby only. I was thinking of running the tent with 300-400 watts of cobs until I can afford to put 200 watts more at a later date. I have s 176 watt high output T5 I can supplement with in the meantime

No, it's being pedantic.

I don't think that is completely fair. Instead of believing the efficiency hype, compare 600W of HPS to 600W of quantum boards. Even only considering the more easily manageable heat output is enough of a reason to use led, but it'll pretty much guarantee better yield. It's also worth considering that prices for electricity differ and the benefit of being able to run a dimmable setup from early veg has its benefits. I run 60W early veg, 250w late veg and 500w in flower. Saves a bit of money.
DrDick had an issue with what I said here. I'd just like to point it out again as I'm not sure why you're trying so hard to have the last say.

I didn't suggest you said that, so I'm not sure why you're getting defensive?

Ok. I'm not sure what to say. I agree with you about CMH being fantastic. We just don't seem to see eye to eye in terms of the simple, measurable, objective fact that LEDs put out more light relative to heat than any other lighting.

I'm out, I respect what you do playing devil's advocate, but taking it so tangental and trying to set up logical fallacies to support your argument isn't the way to go about it.

I don't believe anyone with an education uses 'your' when the sentence requires ' you're' your previous posts are the issue

Then do it.

Dam and I ordered them already!I am going to change the cobs and drivers with better ones as they burn out.The oldest light is 3yrs and will prob give trouble soon.
Honestly I need to change something up.my flower box is 22x22 inches and I have grown one big plant,12 small ones and all between and the yield is about the same for a given strain.IDK if only so much will grow in that small place or if I can boost it with different spectrum of light.I have gotten okay at growing healthy plants(most of the time)By the way I veg under the same brand and style of light,only it's the two cob type.I also have two 100watt galaxy hydro multi-spectrum light with the 3watt chips and I'll be honest,they suck as primary light.Not enough of something.growth is slow and the plants seem awful woody.

Correcting spellings? Has it really come to that?

I really don't think the topic warrants it, but if I have bothered you enough to incite I'm uneducated because of fast typing on a Cannabis forum and forgetting my grammar then I will leave you to your thing.

Thanks guys ,
Reading your bitching and bickering made for a short ferry ride. Honestly their is so much false info , inflated numbers , chest puffing , and salt wifery . You idiots really made my day .
Cheers
