quantum board

After many questions on here and receiving great help from some growers more experienced than myself I've finally got rid of my viparspectra and meizhi light and replaced then with 2x qb288 boards with Samsung lm561c leds:) When they arrived my 3 girls (cream manderin F1 fast version, berry...

hey guys, pretty self explanatory here. Just picked myself up an HLG-600-54b from a gentleman with 6x 2700k and 2x 4000k qb288(the 561s), heatsinks, all hardware, fans, waterproof connectors, for $730 altogether. Solid deal I feel. Just built a 4x 2700k on two slates designed for 3 boards...

Old QB 288V1 thread here Thanks to everyone who supported original Horticulture Lighting Group QB 288 and QB 304. V2 was have possible only from your support. What is difference between Quantum Board QB 288 V2 and QB 288 V1 QB 288 V1 uses LM561C , 5630 package QB 288 V2 uses LM301B , 3030...

Hey All, I'm new to the forum, and new to the DIY LED Scene. My apologies if this is out of place. I started out looking at building a cob setup, and have started leaning towards QB's. I have no first hand experience with either one. The space I'm flowering in is 2.5' Deep x 6' Wide x 7' tall...

So I compleated my lighting for my 4x4x7 flower tent . I’m running 9 qb132 controlled through three potentiometers with digital multimeter feedback. I have my fixture broken down to three zones, for decent control of light intensity. I Have thoughts to add some vertical led strips with red and...

Hi Everyone. A close friend of mine approached me last September and asked me to help him setup his own grow. At the time he didn't have the resources to put anything together better than a couple florescent fixtures. So we set up a very bare bones op. Earlier this week he asked me to help him...

Hello everybody. Since my electronic knowledge is very limited (mechanic by trade) I want to use forum power to answer my question: I bought 2 boards 308 pcs each of Samsung LM561C S6 leds. They are 22 s ,14 p , 2100mA max ,so they running 66V at 2100mA. I am going to wire them in series so...

Both are available from TimberGrowLights but are the QBs worth the extra $120? I'm looking to cover a 2x6 area for flowering. http://timbergrowlights.com/320-watt-quantum-board-grow-light-kit/ - $479 http://timbergrowlights.com/300-watt-vero29-v7-3-cob-grow-light-kit/ - $349

I posted this on another thread, but no one is over there, lol. Anyway, I'm trying to up my game. I run 800 watts of cobs and a RDWC. Mostly Bodhi gear. 7x3 space. My idea is to install some side lighting. I’m thinking of rigging a portable, standing frame with a board like this...

I wanted to get input from everyone about what method , trick , tip , technique you have found to be the FASTEST and MOST RELIABLE way you personally found to take and grow clones. I been growing for a long time but I suck at cloning , I can do any kind of regular growing ( water farm , coco ...

Greetings RIU. I'm starting up this thread to have a single spot I can post garden updates. I find this a bit more convenient than starting up a new journal every grow round. I'll be taking a couple weeks off in April to reset the garden, but the plan is to start harvesting perpetually after...

Greetings everyone It's been some years since i last purchased my MARS II. I think I got the idea via this site actually. So anyway, the time has come for me to get some fresh new gear. Therefor I have been looking at DIY LED projects on google. Nothing has changed, I mean... Surely everything...

Got a 3.5x6.5 tent up . Veggin a few plants under a t5 atm. have a 600 wat hps Or 2 That i can swap in for flowering. But I’m thinkin I want to switch to cob or qb To ease the electric bill. I’ve seen some reviews of Timbergrowlights and growerslights. Wat would the community recommend...

Hi everyone, I currently grow in a 60x60cm (2x2ft) tent with two cheap blurple LED panels, an old Mars Hydro 300 and a Ortoled 4. I have my grow methodology more or less dialed in (just pulled 180g from a single auto) but I want to upgrade my lighting system. My two main needs are to maintain...

Hello ladies and gentlemen, thanks for checking out the thread. Over my 8 years on RIU I've noticed journals fizzle out and the OP bails out leaving the audience hanging. All of the build up, all of the suspense, to be let down in the end.. it's a bummer. Don't worry! I won't leave you hanging...

I've had the HLG 550 for a couple weeks now and it seems to have taken the place of Bestva 1800 (foreign junk) and Mars II 700w without issue. i'm moving up in the LED world. I've still got advanced p300 and I'm looking to return it and spend that money on new, more efficient tech, particularly...

What's up fellas! Have a new grow in the works with an all new light coming soon. The plants are four Violet Sunrise (Sherbert x Tk91) and two Lemon Fracture (Lemonge x Tk91) from Clearwater genetics. Had them in cups under 35w of Vero10s. Transplanted them to 1 gallon pots of coco and...

I've been meaning to get this thread up here for a while, but getting the op built out, then up and running, has taken up most of my time over the last couple weeks. So, here we go. The total space I've got is about 200 square feet, but this area is about 12 feet by eight feet I would say...
