HLG550 vs Gavita? Anyone with experience with either/both?

Most small growers are exchanging air..... You don't need a dehumidifier or AC in those cases. That is where led really helps the small scale. Hard to cram a 1000 in a 4x4 vs a 500-600 watt led. Very different behavior. Some newer mini splits have a dehumidification function as well.
I'm only in a 4 x 4 and when I run a full canopy even under a 600w HID I need to add a small dehumidifier.Bit I'm not running immature plants either. I set it on auto so it doesn't use to much power. Being able to then safety get the 1g per W easily pays for the small cost of running it. Not to mention the piece of mind that having one brings.

I've been in a lot of decent sized grows using dehps here in colorado. My friend actually runs a DEHPS + CMH setup in his basement and his colas are redicuolously huge, but arent as dense as my LED grown buds grown under similar PPFD levels.

It's basic plant biology that longer internodal distance would cause the flowers to be less dense, as the internodes are where the buds start stacking from.

Im not making up shit bud. It's well known LEDs tend to grow denser flowers than HPS for this very reason. Why do you think sativa dominant plants don't have buds as dense as indicas? Because the internodes are more spread on sativas.

Everything is my friends this and I visited this de grow once but nothing of yours so yes you are making shit up because none of what you speak is based off your own experience. I could sit here and post pics of me or a buddy at someone's grow doesn't mean it's mine. You're a data sheet Nazi and you've been exposed and still continue to try and advise people on lights etc. Put up your own grow man even if it's a tomato but you can't because you don't have one. You haven't even used an hlg light or a gavita and you're in here trying to advise on both. Do i really need to go so far as to link your thread asking what hlg light to buy.......?

Just stop it already bro. Seriously we get it you know how to read but you're not a grower it's cool. Stop trying to pretend to be someone you're not.

So where did you read this to regurgitate it? Because you dont have a grow comparing DE hps to LED, so here you are again making shit up you have no clue about or experience with. Just copy pasting what other people have said in other threads.

Did you even buy an led light yet? No we are back to wonderland with skoomd..............lol.............
My led buds have been consistently smaller and denser than my hps buds with the same strain. Yields have been on par once I learned the nuances of led growing. If I was still growing in an outbuilding i think I'd probably be running hps because the IR put off by them mitigates some of the need to heat the building during cold months.

Are you making sure your temps are a bit higher under the LEDs? Without the IR emission an HPS provides, it's nessasary to run 80-85f temps to achieve optimal growth.

And what color temp are your LEDs? Keep in mind an hps is 2100k usually, and does pack a ton of red in the spectra. Not that 2700-3500k LEDs dont, but something to consider I guess.

Lots of people agree that growing under leds requires slightly different techniques from the grower to get the same results as they did with HPS. Having a LUX/PAR meter helps a lot, you'll miss out on a good bit of yield if your light is several inches too far.
This is a production environment. The 4x4s are alternating to mix the led spectrum with the HPS spectrum. You can try and blame it on growing conditions but I won't because except for the large warehouse grows I grow strictly leds and build all of my own lights. Leds are my forte and so far I think even with the top tier leds with over 2.0 ppf, 500 watts isn't quite enough to fully replace a SE HPS. We are redesigning our led lights for ~600 watts.

So have mine I never said the info was incorrect I said we have a poser in here

Lol alright bud. I'm not here to argue with you. Don't know why you're so triggered. This is common knowledge for us LED growers, so if you don't want to listen to it then that's just fine :)

I'm sorry, i am not trying to be mean, but that bud looks like absolute shit, it looks like a mold fest waiting to happen. not sure what strain, but yuck.

It is common knowledge for "us" led growers problem is you ain't one of the led growers. And you keep trying to twist that I'm saying your info is wrong to cover the fact that you're speaking out your ass because you have not done a comparison grow between de and led .You're still shopping for a light. You're a poser, a wanna be, and you're in here running your mouth like you know everything and all your doing is reading data sheets and repeating what you see other people say ..........

I agree. My personal experiences so far leads me to believe that I'd want a minimum of 600 w of led to really see 1000w SE yeild numbers.

I agree, not my pic though. It's from some DEHPS grower here on these forums. Just put it there for context. Just asking for mold :(

correction ... hps does not have very much red relative to the big fat yellow spike. Its that big fat yellow spike that gives hps its deep penetration through the canopy.

Lol how fucking high are you bro?

Still shopping for a light eh? I built my second DIY samsung strip light a couple weeks ago, bud. You can look in my sig. And I have done multiple grows under LEDs, just havent completed a full run under COBs/Strips/QB quite yet. But im about to finish my first run with samsung strips in a 4x4, and just popped some seeds for my other sammy strip light. Buds are always rock hard. Check my avatar pic. Dont know where you're pulling all this bullshit from, bro.

You have never used a gavita or an hlg light. You even admitted so earlier in this thread don't start back tracking now......

Dont have either, im using raw data to make these conclusions. The HLG 600H puts out 1450 PPF, and cree tested the Gavita Pro 1000w DEHPS and got 1830 PPF (a bit less than the 1900 or so gavita lists). Then when you factor in the spectrums of the two, it can be assumed that the HLG 600H is definitely a comparable light. PAR isnt everything, the spectrum is very important too. Not to mention the HLG can be placed much closer to your plants than a DEHPS due to the heat a dehps puts off, though in an OPEN grow room this doesnt matter much.

But you can go over and check out some of the threads where people are swapping from DE to COBs/QBs and take a look.

There's your quote from earlier in the thread. You have no experience with either the hlg light or the gavita the op was specifically asking about. There's nothing in here about Samsung strips and you said elsewjere it was your first grow with strips so after one grow you're an led expert or do you really feel the grow with the blurples count?

You're right. I never said I did. I was providing info on them, that is all. We already went over this, but you're bringing it back up to make me look like I'm a poser that doesnt know anything about growing. Whatever makes you feel good about yourself....

I actually have 8x gavitas sitting collecting dust, I got them for $50 a pop (no bulb) because the reflectors are dented or warped. Dont plan to ever use them now that ive seen what the new LED tech is capable of. If you want any of them, let me know........

I mean considering i've pulled as much as 501 grams from 400 watts of blurples (1.25 grams per watt), yes I would count those grows. And no, that isn't including larf, because I didnt have any. I remove any buds that would be larf early on in flowering. For LEDs that are less efficient than HPS, I was plenty impressed, especially considering I paid only $130.

Maybe you can get those results from a brand new hortilux super HPS bulb with an expensive ass magnum hood under perfect conditions (co2 inc. probably).

Quality wasn't bad either, again look at my avatar for example. Better than what I was able to get using HPS in the past, especially density and trichome wise.

Hence why I swapped to some real LED lighting. If shitty chinese blurple led panels that are less efficient than HPS was doing so well, I knew that I was gonna kill it with the strips. And so far, I have been.
