DIY with Quantum Boards

Exactly, apples to apples.

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.




Hydro. 2 gal buckets



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.



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.


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.

I've grow vertically with LED to great effect. What vertical systems have you considered and what are your constants?
 
I just got a 5 amp, 24V driver and plan to run 3 in a cab with it

I'd be very interested to see a multi-QB120 set-up used as main lighting. Four running at max could really do some damage, I would think. Are you going to attach them to some sort of DIY fixture? That's what I'd like to do - I'd much rather have only one hanger to deal with instead of four.

I'd say that these boards would be better at lower wattage. Remember, they have less than 1/2 the leds of a 288. Multi boards at low power in a cab or other micro grow would likely be the best use of them. I plan to run 3 in a 26" x 30" x26" ( height ) at 38 watts each. I use the cab mostly for breeding but may do a grow in it just for giggles

Humple said:
I know the QB120 is rated at 60 watts without a heatsink, but I'm wondering if putting 4 boards together and running them at max, with a driver attached to the fixture, would necessitate a cooling solution? Perhaps remote-mounting the driver would be sufficient? I don't know, something tells me that I may be on the wrong track here. Building a 240w QB120 light would certainly be a bit cheaper than buying one of the 260w kits, but I'm not sure it would be worth the savings?

Maybe its time someone with experience with DE put it to the test rather than endlessly debate its potential. @ttystikk , if you still have the pic, post your vertical grow with the /HLG boards placed above the trellis, I find that pic very convincing......

kaoss_11 said:
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.

@kaoss_11 - It may be too much PK. I use Mad Farmer's MOAB on the IBL Landrace sativa strains to increase node locations and frost production.

I did a side by side with 2 Holy Smoke Mulanje Gold clones and the one grown in compost and supplemented with MOAB had double the frost and flowers.

Cheers,
Mo
 
What do you mean by constants?

Running 9.3.6 so I doubt it but may be a possibility. Threw back in my hps last Friday and have a huge difference in growth over that last few days. Everything is back too normal. Received my 2700 last night just waiting on the 3 prong and wire in the mail.

Well, my HLG-240H-C2100A just arrived (free overnight shipping from Arrow? Holy shit, that's killer), so I'll proceed with the plan. I'm fairly confident that 240-250 watts from four QB120s will do better in my 2.5'x2.5' tent than the single QB288 at 150 watts that's in there right now! (Not to say that the single is doing poorly, because it isn't.)
 
Getting into LEDs reminds me of building PCs. The same excitement over tinkering to come up with something that is uniquely yours, no matter how similar it is to everyone else's. The same impatience for the package(s) to arrive. The same satisfaction of completing a build. The same bottomless pit of spending. The same exasperated looks from the wife. Haha... Good times. Well, even better times, because the end result is good medicine, not games that I'll get sick of in a couple of months!

I want see this when it's done... I think you may be on to something.... especially in height restricted grows...

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.

Thanks popp you said everything i would have

Thanks! I'm planning to post a build thread once I have all the parts. Just seemed like a no-brainer once I started thinking about it? With the sale price of the QB120s, I'll be getting into a 250 watt quantum board fixture for around $200-$225, tops.

O'rly

Suggest distance above plants: 1.2-2m

m is meter right?
