ditching hps for quantum lights

First of all, no one asked your gender. Second of all, how are you aware of what that little light can do if you refuse to properly test it?
He said is that the 550 ( he) showed, so I clarified that I'm not a he, I don't see the problem with that. Test it for what ? You haven't tested it yourself.
Could have been the way I took the image but I'm sure you already know it's nothing little about this light. You're rude and bitter have a nice day.

I respect that!! Not sure why yor yelling at me though. Im just researching
I didn't know I could yell through a text but ok lol. It's just rough on chicks around these parts so I try and hold my own when I'm on. I didn't mean to yell ( didn't use exclamation marks or anything) but I posted the light being opened because I didn't take the best image .:)

Whats your yields like with your 1k hps?
I dont have a 1kw.
I have a 600hps on a dimmer. I know i could get a pound, if i could be bothered to do all the training etc. Im a lazy gardener, in that sense. But i love the Christmas tree look.
I grow 6 regulars. From seed. 4-6 weeks i flip. Usually just over 4 weeks. 1 week into the flip, ive sexed them. 3-4 fill my 4x4. I dont generally top em. I yield 2.5 - 3 ounces, of colas per plant. With fuck all popcorn. I use a $30 growlush bulb. Talk about cheap.
I might have to change bulbs twice a year, but it still costs bugger all.
Im not discrediting LED's. The manufacturers just, really need to up their game.
Even the penetration too.
You guys really think a single 100watt cob could shine as far, as a single 600w bulb? We've all used a torch before.
I could buy a 1kw LED, with 10 Cobs on em. They're still not gonna penetrate any further than a single 100w Cob.
LED's penetration, and spread, is a big, big issue.

I don't have to test the HLG-550, because I believe the data they provide. You don't, so you need to test it. Understand? Or do you believe the data, yet still fail to see the problem here? lOl.

That video is funny. Dude throws his cheapy Hydrofarm quantum sensor under one point of the light and says "Just under 650 PPFD in the center of the footprint".

Pure comedy.

You don't think its funny the dude thinks he just calculated the PPFD of the HLG-550 by taking a single measurement of the light with a $90 quantum sensor?

I personally think its hilarious. Since you linked the video, it sort of shows where you stand in this game lol.

I really hope these QB lights really are not shitty. That would be devastating. I bought 2 of those hlg 600 qb and will be replacing 2 1k hps lamps and replacing the 3rd 1k hps lamp with this 750 watt cob light i did but never used 1.5 years ago. So basically I'm praying those hlg 600's will relace those 2 1k hps, and the 750 cob replace the last 1k hps slut. Now I'm fucking scared again.
I hear ya on that iam sitting on the cliff on 2 of them I was ready to jump till I saw this iam talking the6

That was so he could see the size of the light because my camera angle wasn't that good. I stated that's why I posted the vid

Holy Fuuuuuck though.
$1000 for a unit that costs almost as much to run as a 600????
You get good quality hoods, and ballasts, hps costs you fuck all in the long run. Then 5-10 grows down the line, the hid user's only replaced 5-10 bulbs. The LED user is probably buying a new light. Electricity, still costed the same, plus they're short a light. Its big $$$$, for little in return.

Even the spectrum too.
If you were growing big pumpkins in your space, youd choose hps, all day.
Fruits and vegetables need wayyyy more red spectrum, than an LED shines.
Your pumpkins would be much smaller. Probably less of them too.
Hps puts on size and weight.
Its so damn good to be able to hit em with nearly all red.
But an LED, for all red, unless its diy'd to the max, you have to switch off half the light. Thats a huge loss as well. Less watts overall.

I also have this I'm going to test out. Supposed to be a beast, but I've held off. So I'm going to try 2 hlg 600's and this pictured 750 watt cob shitter in a 8x12 shed that has/had 3 1k watts hps. Plants in veg now.waiting on the hlg 600's to arrive.

Sorry guys,
I watched the review.
Imho, its not a fair review. The plants were seedlings.
I dont understand his remark about green light either.
Isn't most green light, not absorbable by plants, hence why most plants appear green???
Can sometime please tell me why the green light, is as good as the others?
Why wouldn't it be better to have more of the other?

Quantums have zero problem hitting gram per watt issue.

Done last year :
3 panel QB 304 boards
S5 bin ( OG ) @robincnn ( first gen )
HLG 320h c2800
3500k
320w dimmable
9 weeks

Temps : 77° all day
Girl Scout Glue ( 2 plants )

I'm not going to break down the math because it means really nothing to me in the long run , I did do it to see what I may be doing right or wrong.

Just over 300 grams ... 5 jars and a bud or two extra ( 60ish grams per jar )
1.2 g/w

I did HID before , too much heat , airy fucking buds , extra cooling requirements .....
High power bills , buying fading fucking bulbs , swapping bulbs per grow stage , etc.
But if you like pizza ovens , blast furnaces so be it.

Quantums are basically large form factor COBS with BETTER spread , efficiency , color and less heat. It has better light penetration at the fringe areas of tent ( corners ) and does NOT have hot spots. I get denser / resin heavy nugs more than I ever got from HID lamps . By using these Quantums I just eliminated the HEAT ISSUE with plant problems. Hanging on spreadsheets , graphs and backyard tests really mean nothing .... To the regular personal grower. There is a lot of unnecessary dick swinging.
Also anyone stating that I will HAVE to replace in a year is full of shit. I do perpetual grows , they are running daily . Even the very first rig I built ... 18/6 year round ... No decay , no burnout , I keep power manageable at 60-70% for higher efficiency levels. Mid power levels boost the Quantums LM/Watt.


At the end of the day , whichever light gives you the plants you seek , should be the ones to keep.

A 600 HPS in a 4x4 should get you a gram a watt easily. Personal best was about 1.6 gpw.
You can buy a whole 1,000 watt setup for $.30 a watt, compared to LED @ around $3 a watt.
I'm sure I'm not alone as to being burned by the outlandish claims made by some of these companies in the past. I have a couple sitting around that are 4 years or less old with drivers shot or chips in need of replacing.

I'm not against LED's , they will be the lights of the future.

I think its about controlling the environment though.
Of course your buds are gonna get airy, if its too hot.
Put a bulb in a tube, with a good reflector, and a big extraction fan, and itll be the same temps up the top, as your room.
I know mine is. I only use a 6 inch fan too. Let alone an 8 or 12.
In a big room you can hook them up like that, to each other consecutively.
If your extraction is good enough, you can replace your air, and vent all the heat from the lights at the same time. Its a win, win.
If it was a room full of quantums though, they're naked. Excess light, or energy becomes heat. You're still gonna have to be extracting the heat from the lights. Plus cooling, and extracting.
Its not efficient.

Gram per watt conversations are entertaining as are 80% of the posts on RIU I suppose.
If a conversation was started about what % of peoples seeds germinate and they all said 90%, there would be a shit load of liars in the bunch and if the conversation went to gram per watt I bet the load of shit would be bigger regardless of lighting lol.
