Distance to run Quantum Boards

It really depends on how large the plants are and what strain. After you grow several strains for a while you'll find that they have vastly different light tolerances. Sativa dominant plants are hard to burn but some indica plants don't like the light very close at all.

I would start seedings or small plants about 3 feet from those high output leds you have. If they can tolerate it work the light down slowly to about 18". There's really no need to run closer then that in veg. In flower if the plant can take it you can go down as low as 12-14". That is really strain dependent. 18"-24 is safe. That's a good rule of thumb with these lights. I don't think you'll get too much stretch at those lengths and you'll get good growth without stress.

Watch for the leaves doing this. If you see this condition move the lights up a few inches.


Part of becoming a good grower is learning the language of the plant. This is the plant telling you to back the light off. The leaves will tell you many other things if you learn to listen. =)

 

You fit 10 in a 4x4? I've never flowered that many. Most times I flower 4 and I've also done 3,2 and now a single plant. Highest yield is with 4. This is 3. I got 23 oz's and 8oz's of larf.

 

you are wasting so much energy from that light that never gets to your plants.

 

About 11cents per KW hour here in SE.

 

QB's are best ran in a tent because they do spread light very wide. They make reflectors for the qb260's and some of the other fixtures. There's a review video on the reflectors they raise the ppfd by 150-200 points depending on the spot in the layout.

 

Wipe them with vinegar to clean off assembly oil and spray them with white high temp engine paint. They'll hold up fine like that and the white will make a better reflector.

 

I have QB120 pairs fairly close to these AK48 and Wonder Woman 5 weeks into bloom- they seem to tolerate them close

 

Well one is actual output and the other one is dim.
Dim is NOT an output, it's used to dim lights, depending on your driver you will have 0-10v or 1-10v or PMW dimmer support. Just look in the manual/internet and get correct dimmer.

That way u can lower the lights and use the dimmer and save money and it will run more efficient.

 

Cased Potentiometer with Knob

 

Hey guys, i setup this board today. I bought it from R2T. Its 240w for 2.6x2.6 tent.
I was using a 400 hps before and now my plants are in the second week of flowering.
I setup the board at 12'' from the plants and using the 75% aprox of the total wattage.
I want to know if i setup correctly the board or not really.
Thanks.

 

Looks good to me. I like all the added blues and reds. What diodes are the whites, reds and blues? Did it say on manual that came with it? I really like this MARS TS-1000 they have had out for couple months.. Crisp white color thats a blend of light from 3000k-5000k plus 18 added 660nm reds. 150 watts is what they rate max watts. All tho i get 163 watts on my meter? But i got 8 qb132's cranked to max or lottle higher honestly. Then mars at max. All 9 boards are on a 4x4 fixture i made diy. But i got them bout 10inches away . sum tops r even closer. No burn or bleaching yet. My hlgs are 4 in 2700k 4 in 3000k. The mars looks like a more veggn tone but its in middle of fixture. Beleave it or not but under the mars my plants are more glittery than hlg. And another thing i noticed is under hlg 2700k-3000k my plants stretched more. Next round i wanna flower under like a 4000k. Im supposed to get to b a tester for the new mars ts2000 which is same as my light tbe ts1000 but at 300 true watts and bigger board. Then the other company thats supposed to let me test is a company called HGL. SIMILAR to hlg. pcb boards but 80 watts and not sure on what kelvin tone either. HGL was the first company to produce or come up with the whole( quantum) lights idea. Im pretry sure thats what they told me a other forum. HLG has been around for 3yrs. HGL started in 2010 . its funny how similiar the names are to each other, but i know now what company originally started quantums. Just sum things i thought id share info. If plants can handle more light, then either crank light up higher or lower until they show start signs of not liking it.. Only way i run my lights full blast is if theres air blowing across backsides . if no fan then id turn em down but allways good idea have flow over em. Thx for ur pic heres that mars just to show its kinda like yours✌
