DIY with Quantum Boards

Quantum 3000k - 260w

1. BLUE GLUE - 1 gallon Hempy
She hit 35" tall and is pushing into flowering ( finishing her 1st week ).
Feeding MaxiBloom every other feed ( heavy drinker and feeder ).
PH 6.0

2. ASH ( Arjan's Strawberry Haze)

She's an odd bird .... " supposed " to be an auto but past 6 weeks from seed to veg.
So I HAD TO FLIP HER - she is starting to show Plant Pubes but very thick and vertical.
Some minor side branching - very tight nodes , nice smell . Stacked like a god damn totem pole!

A vertical bush.

I may ( defol ) a little but not sure. So as soon as she transitions I am hoping she will stretch out a bit. And NO ... It didn't hermie.

LOL

I don't know what he's talking about, obviously hasn't paid any attention to this thread. Well here's a 4'x4'x6.5' tent with "just" 4 QB304

Idk about all that... What got ME wanting one, was seeing a friend pull over a quarter pound of lower yielding gsc, out of a 30" x 24" homemade "tent" (just a rectangle walled off with mylar), with a single qb288. Doubt if you like... reality is reality. And in reality, a single qb288 can EASILY flower out a 2x2 space. From my limited experience, ~ 14" away seems to be the sweet spot for flowering. Go ahead and pack a qb288 every square foot... unless you have them dimmed WAAAY down, or have em raised to the ceiling, get ready for some cooked cannabis. Anybody thats ever actually USED LED's knows that you need LESS wattage per square foot - not more. Thats the beauty of having such a cool running light. You can drop them down much closer than HID's & drastically increase the PAR wattage actually reaching your plants. 30-35watts/ft2 is FINE with these quantum boards. Less in early stages, of course. You seem to be suggesting that a 135watt qb288 would be required every square foot. Anybody else think that 135watts/ft2 is required - or even ADVISED? Because Iv personally seen a SINGLE qb288 absolutely rocking a 4ft2 tent.

Got my QB120 and LPC-60-1750, just got a quick question before I hook it up, and yes I checked meanwells data sheet.

The output section of the driver has 16AWG, would it affect(effect hmm this is tricky here for those grammar guys, so will it negatively impact my driver if I wago 18awg to the 16awg wire to the driver?

So, 16awg, wago to 18awg, then the dc male plug is inserted into the QB120. That cool?

I've got the 135 kit in a 2x2x4 and it flowers one plant as well as my Cree 3590s.. Plenty of light!

I agree... though I tend to go by grams pulled, nowadays. My thumbs not as green as some folks' lol I find I do a bit better with 2-4 smaller plants, done ScrOG style. I love the single, big beauties... but my tent doesnt lol ✌

Bro all you new guys on this site do is make outrageous claims with nothing to back it up, you make these dumb charts up that mean nothing. Those lights are junk PCB board lights, oldest LED grow light tech on the market, if you want to see those things smashed up go watch @REALSTYLES break his mars hydro LED, that's the tech those lights use. Junk PCB board tech.

not exactly true. I have seen 2 honest LED growers here. of course they were criticized by the rest of the LED crowd. that being said I have used the bridgelux ED strips which use the same samsung 561 diodes and they are much more efficient than the older bridgelux diode and even most cobs. they do provide more uniform light distribution but will burn plants if placed closer than 15 inches away. plant do require more care to deal with the deficiencies that occur with LEDs and yield and quality was lower than test grows with a 150 watt hps.I'm a T5 PU MMJ closet growers but I like experimenting with other types of lights and from grows on you tube and test grows by green house supply companies my disappointing experience with LED is not uncommon. no hydro shop of garden center in my area carries LEDs and none recommend them. T5s are by far the most popular grow light with HPS holding a strong second place although cmh is a strong and upcoming challenger.the LED crowd is a very vocal minority. why do you let them upset you? or do you just enjoy arguing with them?on you tube the average yield is about 0.3 gpw for cheap multiband leds and 0.45 gpw for high end lights using cree or osram LEDs so when a small group of stoners claim that they can beat conventional grow light by an incredible margin using homemade grow lights most people who have done their homework just ignore them. I could claim 2 gpw if I weighed my buds after trimming but before drying :):):)

Not a problem at all. I've gone from the drivers 16g to 18-22g with wagos no problems.

I've personally pulled 1gpw under COB LED, and I know I can do better. Those pulling 1.5 or even 1.8 are making claims i have no trouble believing.

Before you sneer at people's homebuilt lights or the startups advertising here on RIU, maybe you should have a closer look.

Or don't, no one is here to convince you. They're too busy growing amazing buds under the best lighting tech available anywhere, at any price.

Proof? I just did a walkthrough tour of the new, zillion dollar 'state of the art' CSU LED horticultural lighting greenhouse facility and saw for myself how they're still living la vida blurple, lol

Maybe you just don't know what real actual research and development looks like, bro.
