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

[a mongo frog]

Personally, I haven't quite gotten past the whole different plants needs under white led.

What does this mean?

 

[OneHitDone]

I can say this. The Elite is like 700 cranked up right? Thats to much for my 4'x4'. I now have it dimmed covering one plant in a 4'x4' & about 30"-34" high. View attachment 4115901
Personally, I haven't quite gotten past the whole different plants needs under white led. Big life changes just occurred though & ill be able to focus

It ain't that bad dude. Right now I have a SourD under the Amare Bar8 & one also under the Thouie.
In my flower room, I have more problems under the LEDs then I do under the HPS or MH. Seriously, I can't even remember when my plants didn't like HPS or MH. But 1 out of 3 struggle under led in flower for ME.
I keep trying cuz I see others here w/ happy led flower plants. My main problem is some sort've what i think is a lock out related to plants that appear to more sensitive under the LEDs. Maybe one nute ingredient thing is not photosynthesizing properly in conjunction w/ the fuller spectrum or maybe it's the lack of IR. I dunno n it's driving me nuts. This is the whole reason why I have HPS even hanging in my room. Been doing comparisons for the past 3 runs. And each time I lose a plant early flower on the led side. Maybe not that much plant chopping but it certainly feels like it when you got 3 months into vegging a perfectly healthy monster n it just shuts the bed on me once it gets under high powered LEDs.
As far as An HLG 600w QB or Elite, it does cover said area & has matched my 1000 in yeilds. The Thouie covers more area in an overlapping scenario (especially the Raptor n Solis-Tech hoods I'm using) but the concentration of the Elites light density (has lenses) makes for a brighter 4'x4' then the Thouie I'm using, if you get what I'm saying.
If I had more ceiling height or grew smaller plants then I would've used a one of my XtraSun medium sized hoods & would've came allot closer to matching the density in that space.
I think the HLG 600 would fit my room better. I'd simply bend & fasten a 90• shroud/reflector to go right around the whole fixture. Seen another guy do it vert. Maybe @tstick?
I'd get the QB over the DE & add some enhancement to it.

Are the "lenses" on the 550 focusing in any way or for protection / certification purposes? @Stephenj37826 ?

It's called spectrum deficiency brother - think "Beyond PAR"

 

[Evil-Mobo]

I put one of my 600's up for shits and giggles a clone from the same mom on each side and two similar hso plants from seed one in each tray. We will see what happens not scientific etc but for me and my grow it will provide valuable info then the next run we can do all clones on both sides and get an even better picture. So 600 watt hortilux super hps on one side and (6) Auto Cobs on the other side 3500K . The Cobs pull 59 watts each .

That's it for me

As for the OP, when you ask for help here in the LED section you have to do your due diligence and figure out who's for real and who's full of shit . Good luck whichever way you go .The gavita is the standard and you can't go wrong with it.

IDK MAN. maybe it's the easy Epsom cure everyone talks about. I'll try. My new Veg+Bloom nutes seam to plasticize the plants or some shit. Still don't have anything nailed down to say cuz I'm bouncing around nutes right now. Just that the same plants, getting the same nutes In the same room. If their gonna have issues it's always the LEDs side.
Like I said. Prob just Mag. But Damn. Tried 3 different lines in the past year & they all seam to lack what an led plant (of some strains) require. Hassle.
I'll figure it out soon now. I see More time to focus in the future.
The 3k 90 CRI as well as others are pretty damn full. Maybe it's the IR. THE IririrIriIRnUvanIRNUVA,&MelllloooYelllow.

LED + too close to canopy = Mag Whores for plants/burnt and bleached

HPS A/C hood+ get as close as you want= Natural plants easier to maintain

People don't wanna listen, well maybe some day someone who matters more will come along and say the same shit. This was the basis of conversation behind Smo starting his company bro, why I went with his lights we have the same vision of less is more then we found you use less watts per sq foot and get further from the canopy and the plants are not mag whores and feed less over all.

Anyways another area people slip on is your environment. Getting your environment dialed in will make more of a difference than which of the two lights you use.........

We need to do some catching up I wanna pick your brain about a few things.

In what world can you get as close as you want to an HPS bulb just by having an air cooled hood? Does the air cooling also suck away the photons? Even if the A/C hood can keep the light cool enough for a plant to grow super close to it, the intensity will still bleach your plants. The lux of a 1000w HPS bulb at a couple of inches is surely close to, or exceeds 1,000,000........

Whereas with LEDs, you simply design them to be as spread out as possible and bleaching becomes much more difficult, while the overall intensity remains the same. A 100w COB that is about 1 inch wide will fry a plant that's 6" away, but a 44" long 100w led strip is not going to do nearly as much damage.

I've never bleached my plants with LEDs, and yes that includes samsung diodes. I also dont have issues with intense mag needs.

The mid noon sun can easily get up to 1500 umol/s, and you dont see the sun burning/bleaching plants. Yet people bleach their plants with 600 umol/s from a badly designed led setup. That's because the light is so damn diffused that it doesn't bleach or burn. It's been proven that diffuse light improves plant health greatly and increases photosynthesis rates without actually using more light.

I'm done speaking with you. Have a question look at the grow log.

Thanks

I only see the big mag pull in early vegging. Since I started adding vermicompost to my coir I have not used Calmag, I have neither calcium or magnesium issues now, I run my lights so hard the plants scold me every second night by lifting up their leaves in complaint an hour or 2 before lights off. Then I lift the lights two inches and the cycle continues.

How many watts per sq/ft you running?

 

[ANC]

Bit over 300 over 2x4, Sadly Samsung don't give PAR data but it is circa 51000 lumens.

 

[NanoGadget]

At the distance I'm running my QB right now I'm north of 50,000 lumens as well. Wish I had par meter but I'm able to get a rough idea of what is going on with a lux meter, a spectrum analysis and some math. She is learning to love it.

Situation I am discussing is higher watts per sq/ft

 

[skoomd]

Situation I am discussing is higher watts per sq/ft

Isnt that a pretty extreme situation then? 35-37.5 watts per sq foot of quantum boards/strips/efficiently driven cobs is in the upper range of what cannabis can use without CO2 supplementation.

I look at that and think it's a good example of too much N. not a healthy looking plant IMO?

dont take it personally.

I am sure having it mere inches from an HPS bulb isn't helping it much either.

Ive had my plants damn near touching my old blurple leds before and never had issues though. Didnt get any of the bleaching and mag whoring that he mentioned would happen either.

 

[lukio]

They look healthier to be honest, thats not a light thing though - its a grower thing.

Trouble with a forum like this is there are too many amateurs with massive opinions - myself included...its not a helpful combo.

i have mag hungry plants but im in coco under led and use RO water...so i add mag and unsurprisingly that fixes the issue - weird!

until i do a proper side by side ive decided im 100% not qualified to give an opinion. so im out for life!

Its called all the light coming at the plants from side angles and not overhead. Plant is perfectly healthy with no crispy burned crispy leaves as you are rumored to produce
