Sooooo, looking at the Fluence SPYDRx, there which they say will grow well for a 4x4 area with the light hung 6 inches above the canopy produces an average 455 µmol/m2 /s, about 336 the lowest reading and 507 the highest reading. My questions is will this be sufficient to grow good quality?
this is exactly what it says:
SPYDRx is designed as an early-development stage top-lighting system for commercial horticulture applications, and as a full-cycle top-lighting solution for environments without CO2 supplementation.


Product Data

• PPFD

• ELECTRICAL

PPFD: (μmol/m2/s): 455 avg | 507 max | 338 min
These readings again are for a 4x4 area at 6 inches above canopy.
They are local and I like supporting local business and also like the design so am interested in this light, wanting of course a good LED especially for what the good ones cost...thoughts?

Planning on building 2 veg lights with 4 cobs each on 36" heatsinks with meanwell hlg-185h c1400's
I've built one bar with 3500k for flowering but I need to minimize stretch during veg so I was thinking 5000k (reading through forums this seems like the right temperature - if I'm mistaken please tell me!!). Pacificlightconcepts only has 3500k in stock so would either of these cobs work for a veg light? Thanks for any help I appreciate it!!!!

Yes, the SpydrX will be sufficient to grow good quality. I think you would be very happy with it. A close friend uses the older model spydr and gets wonderful yield and quality so the new models should be even better

For Veg the Spyder X is fine but for flower it is not intense enough unless you wanted to only cover a 2'x4' & push the bars in close.
The SpyderXPlus on the other hand would be perfect to grow in a 4'x4' or 5'x5'. Smart company, great components, one of the best spectrums around IMO too. At 12" above the canopy you can now grow with the proper intensity to flower.

 

[weed-whacker]

yeah fully, 455ppfd( µmol/m2 /s) is good for veg/ peppers that require a DLI of 20

if you have a plant that requires a DLI of 40 min and only 12 hours to give it that you need around 700PPFD

 

[StevieBevie]

Thank you all...my observation was that when they were BML the original Spyder had more light bars, I believe 8 and produced more light, and was higher priced. It appears after researching that the 2 new versions have less light bars, and produce less light that the 2 original versions, but the 2 new versions under Fluence are less money. What was concerning to me with considering the newest SPYDERRxPplus model(the stronger of the 2 versions), was that it says only suitable if used with C02 due to the high PAR irradiation.
this is what it says:
SPYDRx PLUS is a full-cycle top-lighting system for commercial applications, with the power and intelligence to scale from veg to bloom when coupled with a pulse-width modulation (PWM) controller.



SPYDRx PLUS is not recommended for environments without CO2 supplementation due to high PAR irradiation.

PPFD: (μmol/m2/s): 909 avg | 1022 max | 664 min

This looks more suitable to flowering to me. Does one have to use C02? If 664 is the minimum and 1022 the max, mean of 909 and this is at 6 inches, would it not be sufficient to simply raise up the light higher above the canopy? Just trying to learn to make the best educated decision.

I think you answered my question, and at 12 inches for example I would not have to run CO2? I am not ready to take that on yet!

 

[Hybridway]

I think you answered my question, and at 12 inches for example I would not have to run CO2? I am not ready to take that on yet!

I recommend using Co2 in almost any case if you can as I will up your yield 30-100%. When growing at a high PPFD or evenly spread adequate intensity, your plants will want to photosynthesis allot. Good light intensity, spectrum, & enviornment will all go hand & hand with using Co2 to dramatically increase your harvest yields.
I think they make that statement on the FluenceBio web-site about not needing Co2 with the SpyderX (smaller one) is because it does not emit proper flowering intensity therefore does not require Co2 to fully benifit from it as w/o the proper light intensity using Co2 is not going to maxamize your crop alone.
I hope I stated that in a way you can understand?
But Co2 will benefit you in any circumstance.
I don't use it in veg because my plants would grow allot faster then I want them too.
Glad I could help!
Flowering w/ only a 500 PPFD in a tight tent may work well due to the reflection provided but nowhere near as well as the SpyderX Plus that is designed to flower with or without reflective surfaces surrounding it.
FluenceBio does do a great job at spreading their light out to provide a high & even light distribution over our plants.

Hello every1!

Need some help to decide which way to go...

So I'm planning to get 4x CXB 3590 3500k 36V CD bin COBs but I'm unsure about how to drive them.
I see most of people drive them with one driver @ 50W each but I was thinking to go max (one driver per led @ 2400 mA, LEDs cooled with low end CPU coolers with cooper base and pipes and 120mm fan).

Do you think it would be a good idea to drive them that high?
What about efficiency (I'd say in long term) difference in comparison to driving them @ 1400 mA?

Of course I would need to invest more in the beginning as I would need to buy 3 more drivers (instead of one).

Nobody...? :/

 

[Mathematix]

Nobody...? :/

what are your goals? whats your grow space like? etc?

Hi @SickSTi,

Wanted to help you with your question - you can run (2) of the 72V CXB3590 @ 1.4A each and achieve 100W/COB. You can also run two of these on a HLG-185H-C1400B.

This will need to be actively cooled as well.

You have a few options on reaching 200W - they are all slightly different and depend upon the coverage area size and constraints of your growing area.

(4) @ 50W each - great efficiency (56.3%), passively driven, good spread/coverage
(2) @ 100W each - low efficiency (43%), need to be actively cooled, intense beam needs sufficient distance from plants
(3) @ 75W each - so-so efficiency (46.3%) - can be passively cooled, would need a 250W Meanwell power supply to drive 225W (leaves 25 W of unusable power supply)

We offer kits of each type - the (2) COBs at 100W/ea is $299 - the (4) COB kit @ 50W/ea is $399. The (3) COB kit @ 75W/ea would be $399 as well.

Hope this helps - if you need additional info or have questions I'd be happy to assist.

Regards,
Dan

Nobody...? :/

if u r on 240v i suggest you look at the ELG 150 2100 for 2 cobs each at 75W

its a nice middle ground

Just ordered the mau5-V kit from cutter should be in next week

WOW, thanks for all the great information!
I am so appreciative, and yes you explained in a manner that was very easy to understand! This closet is off my bedroom, in our home in the country. I really have no worry about people entering my home or smells, so was not very concerned about venting the room.. There is air-conditioning into the closet, and I was simply going to use a fan or two. How much difficulty is there in using CO2 if you do not mind me asking, and what is the expense of that per month. I assumed the room would never get too hot with the LEDS, so was not really thinking about any kind of major ventilation system. I have another room in the home that is not being used, a regular bedroom, but I did not think it necessary to dedicate a room for growing...

whats your opinion on this light? i read somewhere that heatsink is too thin and that isnt good idea driver on top of it... i wanna buy it as side light for my photon 6 http://www.todogrowled.com/gb/led-grow-lights/8-led-grow-light-tgl-220.html

Ya those do seem to be the 4.850" styles and is using cxb(a?)3070's.
I never like it when a company claims to use "CREE" chips... And nothing else. It's sketchy. And at this point, anyone not using 3590's by now is just behind on the curve. But I know that there obviously is a length of the 4.850" that can definitely handle 4 of them and a very minimal amount of heat from the driver where it is on top of the fins, not creating much if any where heat rises. I just don't know what that length is. I'm sure @Rahz could tell you in an instant.

 

[Diskokobaja]

it says it is cbx 3070 at 3500k.. i dont belive that they are scamming anything i'm just concern with those statements that i read about heatsink and driver.. you can choose cxb 3590 but its 150€ more.

Oh I didn't see that. I just scrolled down and read what's on the page you posted. Didn't click anything.

 

[mauricem00]

at the risk of being accused of blasphemy I have a question about using LEDs as supplemental lighting to florescents or induction lights. some growers use 660nm LEDs to supplement the spectrum of these lights.any opinions on using these full spectrum leds instead of 660nm http://www.ebay.com/itm/231650820816?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT seems they would be more efficient since they use a royal blue led to drive a phosphorus down converter and 70% of the output is in the red band with a broad peak at 655nm.

 

[linky]

I am replacing all my 1k hps's. I am torn if I should be running 3590's at 1050 mah or 1400. I watch growmau5 channel and he recommends 1050 mah for efficiency but I would need/want nearly 1 cob per sq foot of space. If I were to drive them at 1400 to start with how many cobs per sq f would be recommended to give equal coverage/power of running them at 1050? I do not want to be short on light.

thanks all
