Sounds like you would get better results by dimming your 4Ks. I grew some LA Confidential outdoors and I was having the same node issue. I gave a clone of the same LA Con to a local grower who got giant colas by vegging under flouros! Less light makes them stretch. LEDs are way more intense than any light you have ever used. You will notice more and bigger fan leaves. This is the plant trying to protect itself from the intense light.

I worked on a project where they were using LED lasers. You can't see the light but it will blind you in seconds. Wear eye protection.

I do this for a living so I will use rooms and not tents. in my test table 4x4 I am replacing the 4k with a 2700k, its a dedicated veg room. plan on buying 550s if the 2700k gives me the results I think we need.
I will say this the 1 single 260w kit works well over a 4x4 just fine in my opinion. will 2 work better? im sure and 3 would be better than that. in some instances less is more and I think thats the case with lamps.

hlg is working on something in the near future thats a true de replacement
Yes I know a little about NLG and HLG. I've had my light a long time now. And got about 4 Grows out of her. I usually stick to ScrOG Grows only. My fault I didn't know what you were talking about on the first message you sent. my board is 4x 304 boards with 2 drivers and heat sinks that are on the 260. But it's the same I can run it higher but it's fine. Sometimes it could be a pain in the ass getting it dialed in the way that you want it. I had it at 18" a couple weeks in bloom so when it's stretched I burnt a couple leaves, I keep it a 20" in bloom now.
Are you Hydro or soil? Anyway hope you get the results you're looking for I'm sure you will with Steve and Robin from HLG there Good Guys and are willing to go the extra mile to make sure you're happy unlike other grow lights suppliers. Shot Out to HLG :bigjoint::clap::peace:

some confusion but to clarify we are testing a 260 watt kit 4k spectrum in our dedicated veg room. there have been good results but not without some concern. the internodes are extremely tight and the plants are very small. not an issue for some but its a concern for me since I put my plants in at about 2 feet. I spoke with my distro and they are sending me out a 2700k kit.
Reason is we veg with SE HPS lamps and have so for years. plant growth and size is much better and faster for us. In my new location I plan on running led lamps however my current results have been very small plants so if the 2700k mimics closer to what our SE hps lamps do in veg then we are all set.
I have had very long conversations with both steve at horticulture lighting group and kurt at growers lights and both have said that the 550 is NOT a true DE replacement, I would need 5 550s to replace 4 de lamps or 3 260 to replace 1 de lamp. So I cant go by your assurance as its much different than what the source has told me. However with that said the yields still should be similar from what I been told.
I need one lamp thats going to do what its suppose to over a 4x4 space, several rooms with 8-12 lamps is the plan. I agree LED is the future, I agree led is efficient, I agree they use less electricity, I agree they create less heat. I would disagree on light penetration being my phantom de reflector is built specific for overlap which in my opinion hits the plants from several different angles hence the reason I dont bunch plants.

For me this is not about what LED does or doesn't do on a spec sheet or lab or tent as I am convinced they work well. The question is will they work well for me and the team. My concern is real world results in a warehouse or decent sized grow room. I would be a fool and horrible business man if I were to invest 8 grand+ in lamps on results based off a tent. I dont need convincing, I am patiently waiting on results and or feedback from larger garden growers. That vertical grow was intriguing but would not work for us.
I've used HPS in veg for years to great effect. I'm curious about how you bloom?

I used HPS to stretch the plants so they'd work on my vertical trellis, which leads to my second question, what kind of vertical were you saying would not work for you?

Most recently I've used 3000K and 3500K LED for veg and both work great; good growth and they gain height well.

No, light from a bulb is not directional, the shape of the bulb makes it impossible to not scatter the light. A little trig will tell you that only a few degrees of light falls directly downward from a cylindrical light source.
Without lenses, an LED has a pattern of light that fans out from the led in a 105-120 degree, very little exits the side of the diode. Thus, LED is much more concentrated below the light than with any type of conventional bulb, even without lenses. And the science to back it up is out there, you can find it.

if you could show any proof of your findings like a scholarly journal, report or testing that show that my lamps light is shooting in the air I would love to have a read. On my brand of DE you have open or enclosed reflectors neither will shoot light vertically, I actually think it would all but impossible. once again the reflectors are open design and designed to overlap since they are commercial lamps.

I believe you have it backwards, the led light is much more scattered and less concentrated. Either way this is not a debate of wether led does this or hps does that. I am here for information from those that have grown using the 550 or similar in a grow room or warehouse. If they have grown using a de hps lamp previously that would help even more. I have been private messaging with members and they have been showing me their larger plants. If you have any pics you would like to share of you using several hps lamps or several 550 lamps I would love to see them if you feel like sharing.

Yes going passive with fans in the room circulating air they should stay cool
depends on the ambient temps plus the load temps. fans can cool in 3 ways. by bringing in cool air, bya moving hot air away from heat sources and by evaperative cooling as in sweat. fans in a relativlyclosed space esp won't carry heat away if they are surounded by heat. i had forgot this was an led thread.

Would like to see the PAR map of 4x4 with the 260w in there. Certainly would be weak corners.
Two triple slates might be way to go also.

Exactly, apples to apples.
I run two for flower, I wouldn't dare run 3. I have to be careful with 2 due to intensity.

The dudes issue really is he needs to try the 2700k to emulate the growth he is used to getting in veg so he can properly evaluate.
the 2700k is sitting on my porch as I type this. When I leave my building I plan on putting the 2700k together tonight. dimming may have been an option but my fear is I would not get the same rapid growth. I have a few outside plants I through in the backyard just for shits and they are doing great. node spacing is how I like and very lush as usual. I use left over nute water without issue.

I dont want the plants to necessarily stretch I am looking for broader internodes if that makes sense.

Sounds like you would get better results by dimming your 4Ks. I grew some LA Confidential outdoors and I was having the same node issue.

Veg is SE hps some of the lamps use conversion bulbs which was done purposely and we have had great results as well.(yesI know conversion bulbs dont work as well as running straight MH or straight hps but I promise the results are good.) Bloom DE hps. I should of clarified better but your vertical style wouldn't work for us(though it looks to work wonderfully) or I should say work for what I need today. I am far from rich and have everything I own invested so I am sticking to whats tried and true and mixing what has worked for us and worked for me in the past. I saw a thread with the vert led mixed in which I thought was very promising.

Right now I cant play or experiment too much. I have time deadlines for applications and fees with the state and city which aint cheap so I cant experiment and do trials and test too too much. Plus learning a new method, small nuances, learning curve and etc is too much to even think about putting on my plate. Contractors are finishing my roof, brick layers will be done this week. My steel security doors are here and I need to install them before I put the big steel doors on top of them. As you can see I can deviate to far right now as I got a lot of shit going on, on top of maintaining other separate gardens.But you telling me 3k and 3.5k worked well for you makes me feel confident in my decision.

I've used HPS in veg for years to great effect. I'm curious about how you bloom?

My understanding is different but If you have some material off hand I could check out I most certainly would take a read. Im no know it all and im a sensible individual.So further educating myself is right up my alley

But logic tells me the light scatters since HLG sells lenses and reflectors on their website to prevent the very thing you and I are discussing.

Ledgardner I believe his name is has the map on his youtube. I have yet to find a lamp that didnt have weaker edges. only way to circumvent that is run the lamp closer to the canopy which still leaves you with weaker edges, add supplemental lighting, or swap plants around like most growers do.
Would like to see the PAR map of 4x4 with the 260w in there. Certainly would be weak corners.

Thank you all for input and feedback. More information we have the less redundancy we will see on the forums and people will be able to use that search function more.

Can you guys help me out. Im trying to figure how many plants per QB i can do in a 4wx3dx8'? And also how to design my light.

I have 2 QBs ordered and an hlg-320H-C1400B to run them on. Im still in the building stages of the room and im trying to decide how i want to design my light frame. I do plan to add more QBs in the future

Im using the black tubs w yellow lids from lowes that are often seen in grows. So say 30x20" table or tables depending on whats best to do.

Forgive the quality of the drawing, but im thinking either one tub/table with 2 QBs over it, or two tubs each w one QB overhead.

Im also still a bit unsure of what height above canopy to expect to hang them. I see alot of different distances from 10-30"

4 would kill it, use two on, in VEG and turn on all four in flower. (2@3000k)(2@3500k)

Eventually 4 for sure, maybe 6 unless that would be overkill. Im gonna stick with 3000k for this room, if i decide to erect a veg room in next year or two ill use different spectrum QBs in there.

what size pots, what media, how long vegging, trellis or stakes. A lot of variables there.

Well, thats kinda why im here. As of right now im thinking hydroton for media in not yet chosen sized fabric pots.

i will have a 20x30 table i can make up to 14" deep.

Im not sure on veg length but im thinking 2-4 weeks

Probably scrog net.

Where would be a good place to sell my black dog phytomax2 800w led lights at?
That's my problem in an illegal area. With other tech like computers and shit I can offset the cost of new gear selling my old stuff lol, have no clue how I'm gonna try and sell some led strips or big ass hps lights and don't want to dump them and don't want to store them...

wanna trade? I think we can work something out so we can have a proper side by side done.....

Do it!!!!

those guys at black dog are chodes, I met some at canna expo in SD last year. when I mentioned cobs, he said BlackDog is the very best, and that they were loosing money selling them. then that he didn't have time to explain because he was too busy selling 10's of thousands of dollars in lights.

most every BlackDog I seen on youtube has been removed to copyright.

they have a kind one, but I also most want to say they are pretty much the same people.

if you do a side by side, don't say the name of the light, we will know though.

Quantum Gardens :

Tangerine Dream was pulled from the tent and is in ICU ....LOL
I am still trying to correct the necrosis and have her on water diet , she is throwing new pistils but I'm just trying to keep her on track.

image.jpeg image.jpeg

Now the KomaKush is occupying the tent with 4 panel QB ( 3500k ) with COB ( 3500k ) .
Power is at around 280 ISH ......... but if I need to I can push out much more by upping the dual dimmers. This strain will probably make me raise rig slightly but I have plenty of room to raise ... She is heavy Sativa so I got time.

image.jpeg image.jpeg

Lastly .... The green crack ( green pot ) and 2 GSG ( bags ) are thriving very well.
I suggest giving DR. EARTH products a shot , plants are vibrant and green. I use their " LIQUID SOLUTION 3/3/3 " for veg with Dr. Earth Seaweed solution ( at last week ) before flip at watering. GH MAXIBLOOM for flowering although I WILL try their FLOWER GIRL bloom Nutes after this run just to compare.

Quantums are chugging along with no problems ....

BatWing Quantum is now on nursery duty with new seedlings also ( godfather OG )
And The 260 Quantum is still with the Blue Glue and Arjan Strawberry Haze.
So I will update later at some point ..... Love this thread !

Time for my Arrogant Bastard Ale - Cheers
