The irony. It's palpable.

Dude you all got burnt, of course im a grower, my internodal distance has got futher not less as that yeilds me more of each branch as oppose to when i started and tried to keep branches like a few inches. Feel free to google my progression here over the years as im sure i have posted similar pictures seven years ago and every year since.
Now that we are all in agreement that this kingrow can actually grow just fine and even in 30 plus celcius air temps like what weve had in the UK with hps recently im asking whats your point because as far as i can read for 20 pages im still right and your all redundant, even more when we compare plants
FYI i didnt want to compare plants and dont feel i ever need to...

Well there is this thing called science and thermodynamics which will work out most heat and light for most sources, it goes on to state that hps heats the air very little and that being a light most heat is of radiation wich passes through air barely heating it.
You noobs have been confused on where to place your thermometer, why ambients are all that matter and not how hot if feels at canopy level even that your inside air is basically the same temp as the outside when using extraction, hec we could plot the speed and work the maths to show that that air is heating up by well under a degree overall.
You refuse to put your head into some science..... thats all and i havent been wrong on much over the last couple of years but you all been confused about simple topics like boveda and how to dry and cure, hermies, trifoliates etc etc etc.
Like kingrow 9 - Noobies 0 so you can say whatever but time always shows who is right or wrong here
I'm glad you don't have heat problems in your 2x2 tent...ironically

If your not getting your money back for the juice you use ,plus a good amount of bud for you to do what you want with.Then I can see you ended up with a few Oz tops from LEDs un less your using a good few of em.Rather than buying led buy a cool hood ,and stick with hps.Look more into Air movement ,and getting the heat from the Light or lights out of that space has quick has Possible.

Lets do that., hec we could plot the speed and work the maths to show that that air is heating up by well under a degree overall.
What airflow will it take to remain 1 degree C above ambient with say a 600w HPS?
Please show your math

Damnit Taco, I went and put another plant in there...
I'd hate for them to end up like this, what should I do?

I def want to see him work this out an see his math to back up his claim he can do it as well!
But here's a few points of data from my room.
Floor temp =71f
Wall temp near top of the room =73f
Tent wall temp=73f
Canopy temp under the light = 70f
Floor of tent temp= 71f
Roof of tent temp = 73f
Top of hood temp = 79f
I use a 1000 watt hps in a xxxl reflector in a 5x5. Theres a 8 inch inline fan that says it pulls 750 cfm. The line goes carbon filter, hood, out the tent, out the room, then fan. For intake I'm using a 10 inch fan (no clear cfm rating) to pull cool night air. I'm not using any A/C. These reading were taken directly for this post just now.
The lower leaf temps than ambient are do to transpiration. It is true it's simple to cool a hps, it's not true they dont generate a lot of heat, as all things that consume power generate heat in relation to power draw.

If that were the case then HPS would not produce enough light energy to grow much of a plant. The Law of Conservation of Energy.

Maybe you should research the construction and function of bulbs.
Yes theres gas around the filament in a lightbulb. But it's the same tech

No you should look at your statement and then look at conservation of energy. Have a nice day.

While that's a well put together video it seems clear to me hes selling a product not providing the highest quality info. If he had used a 8 inch fan I'm sure he would see closer to ambient tent temps. His claim 200 and 400 cfm cool equally or 200 does better is misleading. He also got the tent and everything in it hot first, then tested the products he wanted to discredit, and moved down the line. Pretty easy to see what he did there.
There was good info in there, I just wish it was structured a little differently. Thanks for the link

Dude a lightbulb is literally a filament surrounded by gas encased in glass. A heater is a filament. In both cases electricity is used to heat the filament. What about that is wrong. Point it out.

He sells HID... he owns a Hydro store.
Seemed like a pretty well done test to me..but anyways..

Btw if you need a diagram of a lightbulb or a heater they are easy to pull up on Google and you can literally look at a labeled picture. @Stink Bug

If you only that easy. Reading through this thread its pretty obvious you either refuse or simply cannot grasp science.

I get that he sells both. My friend also owns a hydro store, and loves selling LEDs because it's a better profit margin and he knows they will be back to buy a differant led and then on and on. He literally laughs about it.
Just my perspective after watching the video, like I said, it's well put together, but the order he did things, way he said things, and the things tested gives me the impression it was never truly ment to be a fair test.
I never really see temps 10f over ambient, that's just crazy to me. As you see in my data a few posts up
