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

thats good going, man! i remember you saying you were pushing pretty high watts.

im dimmed to 1200 per 4x8 and around 850-900ppfd last round. smashed the pants out of two tents. no idea of weight but im gonna bump the ppfd a touch next round just to see. i cant run Co2 so 1000 is pretty topsy i think
i cant run co2 either. do not go over 1000 thats what i was testing i dont think is does anything going over 1000ppfd

The sunlight at high noon in mid summer can easily be 1200-1500 umol, but people dont burn their plants from that. When in doubt, add more led emitters :blsmoke:

I hear ya bud.

I have tested the following;

1. Running my set-up with inlet and outlet ventilation system
2. Running with inlet and outlet ventilation system + Dehuey
3. Running Dehuey without inlet and outlet ventilation system

And without a doubt,
Option 1 was by far the best in terms of control, ease of use and efficiency.
Option 2 is good but I can get the same results with option one with a lot less fiddling and electrical usage.
Option 3 is poor, and not something I would recommend.

You can control humidity (moisture in the air) by ventilation alone. Therefore operating a grow room with proper/adjustable ventilation is/or should be standard practice, no matter what lights you are using!

This means HLG's definitely have the advantage over HPS because, whereas you need to run aircon + ventilation in a room full of HID's especially on hot days, you would not encounter such a problem in a room full of LED's, that has a ventilation system, with a good air exchange capacity. This is but one of the advantages a decent LED system has over an HID system.
Any passively or actively cooled led running @ 600+w is creating more heat in sealed or any room then a vented 1000w HPS. 2 , 600w vented HPS is prob cooler then 1, 800w led.
Now that im running the mini-split I have no issues. Prior though, 2 ,1400 btu Stand-ups wouldn't cut it till I replaced 1500w of led w/ 2000w of vented HPS as an example.

how do you have the environmet set up in each room? the fact that you said your led plants are less healthy than your hps thats grower error not the light(not trying to be a dick) if the led are lees healthy at any point the side by side needs to start over a legit side by side would have equally healthy plants and you really need to count all the tops/bud sites and make sure they are even on both sides. i dont expect anyone to go to the much effort i certainly wont haha.
They're all in the same room. All go in perfectly healthy. All get the same feed. Some strains struggle in the led side. Same strains are fine in the HPS side.
Grower error I guess would be not making a special change for the led plants yet. Not positive what it is. I'll have try the Mag thing.

do a little epsom salt instead of a calmag supplement if you can. if the environment and nutes are dialed for hps im surprised the led dont look worse every grow

lol not in the comp but now i wish i was!

its your bullshit after trying to point out led guys "lies" thats really offensive. im obvs struggling with that... why be a massive hypocrite? its so dumb
Dude, to say the MASS MAJORITY of the led submitted #'s around here or proposition that it's normal is not outrages w/ no evidence rather then some guy saying he did it on You-Tube is basically selective listening. And so misleading & rediculous. Kindve like my ex did, only hearing & believing what fancied her liking.
I've doubled my GPW on average using 5/8 the power. That's alI can say. Not 2 GPW, or 4 #'s in a 4x4. I hit 1.5 a few times w/ my SunCloak but aside from that .75-1.25 is pretty normal on my space.
You guys should keep in mind, most people don't grow 12-16 plants in a 4'x4'. I'm lucky to fit 1.5.

I'm not sure who's numbers you're referring to, man? I run 15 per 4x8 and I've hit pretty good numbers with leds and the other guys around here do too. If youre gonna call bs then i want some names or examples please of "submitted #s around here" cause I might of missed it? Or it's all nonsense

Pleasdd to see your girls looking perkier in general this round, dude.

Interesting, and how many HLG 550's have you ran in that comparison, do you have some pics we can see?
