SF1000D vs SF1000 2022 revisions ¿Is there much of a difference?

There's changes in this year's SF1000D revision

PPFD Map is quite similar.
210 vs 218 leds, both use the same LM301B leds now
199umol/S vs 250.43umol/S
2.5 umol/J for both
SF1000 with a dimmer, SF1000D without dimmer
You can see the full specs in the Spider Farmer website

Yeah a much better mean well power supply with a dial

The other is el cheapo. No dial. No circuit redundancy..

Way longer lifespan on the other. Trust what I am saying.
I was talking to some rep from Spider Farmer about the SF1000. And they say "Hi friend, now we have all upgraded to the Spider Farmer drivers". So it looks like they ditched the meanwell ones.

I was with you until you said "Trust what i am saying" :bigjoint:
Good response bubba. I like your style
But in this regard I was trying to give the short answer

The drivers in the updated version is pretty good actually even if it's not a mean well... Anything is better than the base light and if you're going to veg get the better one....


The logic in the second light is much better

You want the second one with far red.

And every part of the grow/Bloom process. It's Necessary to be a Horticultural Les.
Agree fully but if I was going to make a choice I would lean into red not blue light...

The full spectrum covers that nice and I will always take a little less dry weight that's higher in quality.

The engineering in these lights are often missing the mark on far red. Cause the engineer doesn't grow much cannabis. Or at least not really well

Get yourself an agromax two foot pure UV t5 and put it in there alongside the LED and you'll see a huge gain

Plus it will control mite's and or fungus

Only true when the short, broad wavelengths are misused.

Labs say much different bro. I think many believe this because the few running a broad spectrum are not doing it right therefore the results reflect little differences. Take GLA vs Mars for example. 1oz gain & i know the labs will be higher but not nearly what they could have been. They lead RIU in spectral knowledge now that the "A" company isnt here.
Those bunk sumplemental bars aren't matching a true SSL, desighned specifically leading lighting CEA technology.
This first time led grower in living soil was gifted some leds for winning the cannabis cup. One was of the Highest Electrical Efficiency light out at the time & still is. Also a bar configuration of x6 bars. 2.45-5umol/j vs 2.9-3umol/j. He yielded 12oz more, 30% more flower sites, more color, stocky buds, Aroma, 12% higher thc (not Even trying) doubled the terps & Cannabinoids as well as popped for cbg/d/n when the white plus heavy 660 more electrically efficient lamp did not at all.
Labs came out high so a second one was done & sure enough the first lab inflated. One thing remained though. The differences.
Its been common to retrieve ones Roi (or free light) when comparing harvested dry weight or yeilds since the 3rd bar light & still the only fully modular, Hortri-Centric, glass covered, doubled up thermal mngmt, sliding, pivoting, no gap spectrum light out. This has been very consistent with proof of growers averaging 8oz more of a better product in a 4x4 since 2018. That's a fixed spectrum too. With a 10% light loss but diffusion gain ( much more benificial then raw photons), the two 660w lights did x4 sbs's here on riu by an unbiased, more of a fan of the competitor do to fan base. Yeah, until results & even veg results rolled in. Each even parameter sbs resulted in higher quality, bag appeal & 1/2# more in the 4x4. Shit, that's just one guy here on riu in 2018, NM the rest of the growers who are highly recommended to sbs vs their favorite les & if not fully exceeded your expectations then you get your full refund with shipping. Tough to do with led newbs but the transitioning is 50% easier so almost never a hiccup when following recommend instructions. Another thing companies have wrong. How to use their lights Now that the Hortri-Centric series has been out since 2020 & since 2021 with full pre-programmed spectral control on a controller of real spectrums. One similulates the morphological effects of the sun but better for indoor use. Nothing can touch it. Literally. They're trying to copy but just keep botching it. Breaking the so called laws of lighting science. Lol! I can Garuantee you no uvb can touch what is achieved within 400-750 only. And the benefits of violet is 10:1 as a whole to the grower & environment.
In this last sbs, The other light had a 70w veg advantage & was at least .5umol/j higher. Not to mention the competitors lights spd is similar to your description of red heavy tho Lil n/ir. It was a complete blow out.

Short version

UVB increases Terp oil and THC quality and complexity...

I'll try a Terp hog over 35% THC flower that doesn't get me there

I have both old and new. Both with dimmer. But I like new one better. Idk what it is. But I see a difference in my plants now that I use the 2022 for sprouting seeds.

I've spent tens of $k on LEDs for fifteen years now and have had shit custom built by myself. I also fuck with building computers and electronics for decades


I read the science and advancement in technology also but go with what produces real results


That's all I can speak about

Good man! Nice flowers BTW! Logically speaking & hypothetical for the more sensitive folk. If Shane from Mi-Gro, Or even better, The Brucester tells you an spd is optimal for cannabis and instead you use your own common sense, compare the two & yours comes out on top by a long shot. Consistently too. Can any of us honestly say that a fixture of 3.0 umol/j or whatever is more efficient then one at 2.3 umol/j if the latter is bringing home better & more???

Keep your ppfd and efficiency in g/watts bubba


I can construct a better light with a stack of cookie sheets and be 97-99% as efficient and with superior results verses weight

It's apples verses oranges in my mind. I'm all about the results, inter nodes, hormonal response.... What makes the plants happy

Key is color of the full spectrum... plus IR 660 and UV ratio. Anything over 3800k is overrated IMO

Personally I like the lm301h 3500k the best

Plus every grow situation and footprint. Cultivator selection ECT varies for what's ideal. There's a lot of variables to consider is what I'm saying
