Lighting Cobshop.net info, questions and answers

Aye, nifty way of saying every single watt provided to the light is converted into heat..... 1 w ~ 3.41 btu...... I wonder when it dawns on everybody that a "light" is really just emitting heat in its various forms, light being one of them.... If in doubt, go sit in the sun-light for a little while......

Maybe you should label the "lights" in both w and btu, possibly also include joule and calorie.... Might cut down on the number of punters asking how much heat your 55 w light "gives off"..... Lol..... Rather than being focused and reflecting on how efficiently the light produces PAR heat.....

Welcome to the cob zone. The easiest option is the autocob 3500k. The spectrum is perfect for veg and flower. The 4000k and 6500k have much more blue making them more for the veg stage. Total heat from the cob is right around 185 btu's. Any more questions please feel free.

Thanks!

Very few care about the technical aspect. A few months ago I was told "par is some fictitious number us cob guys made up and lumens were the real deal"
It's impossible to please everyone and it's even harder to educate people when they don't want to be educated. People want lights that work, they want the least amount of heat and they want someone to help answer there questions fast and in as few sentences as possible.

There is relation between wattage and heat. If we did a poll and asked which gave off more heat an autocob or a 60 watt fan.. 98 of 100 people would say the cob was warmer. Right? The answer would be long and the answer would be correct but I'd bet that half the people, even the ones that know and trust what I say is actually true would question it.
The fan puts off more heat.

People can relate to btu's and most like to know what that number is. People like comparisons and the analogies, they like correct answers they can relate to. Not a math problem.

Yes, exactly what you say..... Sadly!

..... You can lead the blind, but you can't MAKE 'em see..... and when the blind start leading the blind......

I don't mind debate or tech talk but I despise the trolling. Here of all places. More than welcome to join RIU with the rest of them.

So I want a 3500k autocob. Was gonna get two, but I think one will be just fine considering my space is only big enough for two plants. My space is ACTUALLY 22"x 34" . Currently I have a 300w mars. The 3500k would be awesome next to it, side by side....SO.. I think just one would work wouldn't it? Basically half the tent. the footprint I would need covered under the cob is a 22"x 17"

I have seen this same style setup a few times. Not only will the cob add some power to the tent is will fill in the missing spectrum left by the red and blue lights.
