So plenty is litterally only you stating your own opinion? Cant quote a SINGLE reputable source, unlike what I've done?

The mega rich will have to leave Earth sooner or later. They are destroying it so will have to move some where. They need us to create the escape vehicle whilst they still have some time.

Well, I have an engineering degree, so I guess that means I know nothing lol.. It's why I keep urging you towards an institution of higher learning.. It's where I attained my understanding. Scour the interweb lol, look into the science, you'll see.. Aside from that I'm not sure what else I can tell you. Normally I would consider myself an authority but hey, lol WTF do engineers know?? Did you check your inbox? I sent you a lengthy explanation.
On the topic of Apophis... I've only pointed out a coincidence. It's obvious no one can say for certain, so chill (it's a weed forum bra, lower that BP lol
), it's just a general topic for casual discussion...

We all know we are destroying the earths ecosystem that we depend on to supply water and breathable air.
We all know that Science Fiction often becomes science fact.
Sooner or later the human race will have to leave Earth to survive. The seats wont be inexpensive or numerous.

So you think I should ignore countless results on google, led manufactures here on this forum, and just trust you when you cant provide ANY evidence beyond "trust me I know stuff"....Well, I have an engineering degree, so I guess that means I know nothing lol..

Since you know stuff an went to college you should know how to find some supporting evidence.
Ya I saw the message you sent. Still didnt gave any evidence, you have a really hard time with that bit dont you?
So what's your grow specs? Sq ft an watts?

Are you able to link something relevant? That doesnt say 1000 watts of led make less heat than 1000 watts of hps.

Many times the only thing worse than knowing nothing is knowing just enough that you think you know everything.
Pretty sure that's the case here.

Lol yup. You know very little. Agreed.

I don't know what it says as I didn't click on it but yes 1000w of led will make less heat than 1000w of HPS. One runs a Gas and one doesn't.
A watt of energy is a watt of heat but with HPS first we have to heat a gas to make the light. With LED it converts the energy straight to light.

Atleast I can post links to back up my claims, something you simply cant do.
Also still waiting to hear about the grow your too ashamed to talk about.

According to that link your incorrect. Led manufactures agree so imma talk their word for it thanks.
If we were comparing btus per lumen youd be right all day, but we arnt.

I found it strange when I went from a 600wHPS SE to a 630w DE CMH that my tent temps dropped. Must be something to do with the efficiency of the square wave ballast.

Did you plug your 600 watt hps into a kill-a-watt to be sure it was pulling 600? A lot of em pull a bit over spec, especially older units.
Doesnt matter if its fans or heaters, a watt is a watt.
As much as led companies exaggerate claims youd think they wouldnt say they generate the same heat watt for watt... and every link on google... it must be a big conspiracy to keep everyone in the dark for the giggles...

Naa not that interested, just an observation.
A watt of energy = a watt of heat. I think that's a law isn't it? Its the efficiency of converting that watt to light. LEDs are more efficient therefore create less heat than a HPS. No gas to heat first.
anyways kinda off topic.

Exactly, leds produce more lumens per watt than other types of lighting, so it's starting to be that 500-600 watts of led can replace a 1kw hps. Just like some people are able to replace a 1kw hps with 630 watts of cmh. I agree with all that.
What this guy keeps saying is that 1000 watts of led produces less heat than 1000 watts of hps. That's just wrong and easy to find sources for.
He refuses to even try to find a source and says hes a engineer and I dont understand thermodynamics and that's ALL HES GOT lololol

Lol you like a little dog that can't stop nipping at my heels!
If you don't understand the thermo, what good is another source going to do to help you understand? I'm telling you that you have to look into the thermo! I don't have all year to teach you the basics, so you'll have to look it up on your own. Personally, I've already done that and demonstrated my aptitude to peers that have the authority to validate (sorry, that's not you). If you can't follow the math and comments I've provided then it won't matter if I give you 1000 sources. You'll still deny. You need to learn the science first so that you can finally grasp what I'm saying. That's step #1. Once you do that it will all become clear and you'll see just how pig headed you've been. I imagine you may never want to log onto this sock account again once you see the light lol...

FYI, if anyone wants to see the personal explanation I inboxed him, here it is. It was an attempt to confine this thread to Apophis, but the troll just can't help himself lol

Watts are watts, but ambient is only air temp, much more to a grow room than air. Not all energy is confined to the air.
Also, 1W of thermal creates a different effect on air temp than 1W of kinetic, or 1W of chemical. They are all 1W but they are all different forms of energy.
Light is NOT thermal, it's electromagnetic. It can be transformed into thermal when absorbed, but the air isn't doing the absorbing, the walls and buckets and plants are the things absorbing. These things have certain Cp's (heat capacities) and k's (thermal conductivities). How well your individual grow room is able to conduct this thermal away (depends on the Cp's, masses, volumes, k's, ect) is going to be the determining factor whether you reach the same plateau as an equivalent wattage HID. They could reach the same ambient plateau, but if this were to happen the HID will reach it at a much quicker rate. If your grow room is conducting heat away, which most grow rooms do, then the LED or more effecient source will have a lower ambient plateau temp because it's not absorbing or accumulating as much energy in the air as the HID.
A threshold will be reached where the rate of energy in = the rate of energy out (for the walls), and if this energy is re-emitted back into the grow then both types of light willneed equal convection but most grow rooms expel heat.
This is what I mean by rates matter. The grow rooms are not closed systems. Because the grow rooms conduct... a certain % of theenergy thrown on the walls will "disappear." Obviously not really, it doesn't disappear, it's transferred outside, but as far as our growroom is concerned, it disappears. There is no formula to determine whether or not you'll reach the same plateau, it's all individual, but even if you do happen to reach the same plateu, the amount of time your AC has to run is drastically reduced from "all day" to "end of lights on." Heat isn't only measured at end of lights on, it's measured & managedthroughout the grow, so even though it'spossible they could reach the same ambient temps, realistically, on a per hr basis, theyare not the same temp, and the more efficient source operates cooler. The time it takes for the energy to equalize matters. Not just the final temp (if they happen to be the same).
