Ha ha no worries here about that lolive seen someone try to cover a space like that with gavita it didnt go well at all guy lost a ton of money had to move out of his place

I don't defend or even use DEHPS
You think growers Veg in their Flower room making a light for veg necessary in the flower space?
You think people don'y veg under hps in a commercial setting?
You think led makes more potent weed than HPS, LEC, or LEP? Even T5 for that matter?
good experiment your canopy looks a little less full than my friends that failed hopefully those fatten up for you im sure you will have plenty of bud if your growing for personal stash
Yep i dont depend on selling it just seeing what kind of numbers i can get with the single sourcegood experiment your canopy looks a little less full than my friends that failed hopefully those fatten up for you im sure you will have plenty of bud if your growing for personal stash
i dont need to explain myself you sound like a damn viparspectra ad people like you give led a bad rep. have you ever grown? dehps work stop with the spectrum bs.How so exactly? LOL. You arent gonna cover a 5x5 grow space using a 1150w DEHPS, so I figured that would be a good build that would. And yea....
1000w of those samsung strips is right at 2.2 umol/j after losses n shit. So 2200 PPF output.
A 1150w DEHPS right at 1.8 umol/j has a 2070 PPF output. Then there's reflection loss from the hood, plus refraction loss through the glass. 10-15% reduced PPF easy, so 1800PPF.
Obviously the LEDs (3000k) would have a superior spectrum overall. Both for full cycle use and just in terms of how much red/far red/green wavelengths are in it, which are the main photosynthetic drivers.
Here's a eye hortilux 1000w de SPD

And 3000k LM561C SPD

The DEHPS spectra is just dominated by yellow wavelengths, no good. Therefore, all of the other wavelengths relative to it are quite low. Sure there's a decent amount of red, but the 3000k LED has way more red spectra, and especially notable is that it has 4 times the relative amount of 660nm far red, the most important wavelength. Overall, there's a significant amount more red on the 3000k cob than the 2100k DEHPS.
Oh, and green is nearly as photosynthetically active as the red in intense white light. And it penetrates leaves like butter. HPS has no green. Scientifically speaking, the LED has a more photosynhetically active spectra than the DEHPS. And it still packs plenty of blue light which (along with UV) has been shown time and time to increase trichome production.
So you combine that with the raw 20% higher PPF output on top of it, and it's a clear winner....
And while most people would be crazy to run a DEHPS in a 5x5 (even AC/DE), let alone bumped to 1150w, it doesnt even provide full intensity in that space. While the LEDs would emit about as much heat, they would provide a much superior intensity and spectra overall and will take a 5x5 to 4 pounds.
i promise you will yield more with the same light in a 5x5 tried to tell my friend this he didnt listen said the same exact thing as you when i saw his grow halfway done. not trying to be a dick just seen almost this exact situation play out. but hey rent free means your almost all profit! my guess is you will barley hit 2 lbs buds will be kinda fluffy and a ton of larf unless you lollipoped them. 4lbs is impossible for you imo. again not trying to be a dick but you should be more realistic just so your not as dissapointed. definitley throw some updates up let us know how it goes!Yep i dont depend on selling it just seeing what kind of numbers i can get with the single source
Before i add leds so i have a baseline.
Its roughly half done so she should fatten up
If i can hit 4 lbs on 850w i would be happy but i doubt ill hit that this run. We'll see
My rent doesnt exist so i wont lose my place haha
i dont need to explain myself you sound like a damn viparspectra ad people like you give led a bad rep. have you ever grown? dehps work stop with the spectrum bs.
I've been running the HLG ELITE 650-700w & 1000w HPS in the same room for going on 3 grows now if anyone has a question I may be able to help.
That would be good cause thats just half the room haha 2and 2 make 4 if that's what you meanti promise you will yield more with the same light in a 5x5 tried to tell my friend this he didnt listen said the same exact thing as you when i saw his grow halfway done. not trying to be a dick just seen almost this exact situation play out. but hey rent free means your almost all profit! my guess is you will barley hit 2 lbs buds will be kinda fluffy and a ton of larf unless you lollipoped them. 4lbs is impossible for you imo. again not trying to be a dick but you should be more realistic just so your not as dissapointed. definitley throw some updates up let us know how it goes!
Take an ir gun reading of some colas under an HPS, you'll find they're 10-15f warmer than ambient. RIP terpenes!
Have you ever used ANY Hps lamp bro??
Again you have no idea what is happening in the real growing world.Admittedly not in a very long time, but did you even test it for yourself?
This is the surface temp of a cannabis leaf under a 1000w HPS @ 24" away

Imagine what a bud with all of their extra mass and water content would be at if the leaves are that much higher.
What you're showing is the main reason why his transpires more/photosythesizes faster & grows bigger buds. Just so you know. I welcome the 10• increase & have used it to my advantages & technique since my 3rd grow.Admittedly not in a very long time, but did you even test it for yourself?

Many west coast growers (which arguably set the standard for cannabis growing in the US) live in coastal zones where day time temps never even reach the overly hot 88.7 of your example.
And we run at night bro!
Peeps be setting up a whole garage of either SE HPS or a few bucks more for DE's and still aren't in it much more than 1 of your lights all in. And they are growing pounds of the dank.

That way you can preach to those who actually want to listen to what you are saying![]()
