Why garbage?Spider Farmer is overpriced, but Mars is garbage. In the end a little more money will go a lot farther.
Completely unrelated but you'll be cooking those tiny plants with that much light. Save yourself some power and do them plants a favor and turn one off for now and lower the other.I went with 600 watt MH air cooled and then the other half Spider Farmer SF400 in a 5x5 tent. View attachment 4797595
Watts isn't necessarily the key measurement for lights. I personally would go with the light that has a higher output of micromoles (µmols) per second, the best light distribution, and is dimmable. Micromoles is the measurement of photons per meter per second.I'm looking to add about 200W-300W to my grow, the Mars Hydro TSW 2000W (300W) at $269 seems like a good bet... the Spider Farmer SF-2000 (200W) is 100W less and $300.
Are the Spider Farmer lights are much better over Mars, and if so, in what way?
amazon pretty good with returns thoughI was recommended this light, The GooingTop QB2000, supposedly almost as good as the Spider Farmer SF-2000, Samsung diodes and Meanwell driver, but with 240W for only $150.

Sounds like an amazing deal, but some reviews were saying the build quality was a bit shoddy (exposed wires, etc... I have to leave my apartment sometimes for a few weeks, would make me a bit nervous. My neighbor checks in for me every few days, but still).
Would be stoked if it didn't seem shoddy... $300 for 480W

In your opinion, how much do the efficiencies really matter? Between let's say a Spider Farmer and something like the GooingTop light?My experience with boards is that you have to count the actual diodes to compare them because many will list similar wattages. I got my two boards from Ecofarm and I'm pretty happy with them, they use samsung LM301Bs (It's like $15-20 per board more to swap them for LM301Hs and I'm not that bothered by the efficiency difference) and ran me ~$190 apiece with shipping, it came with a dimmer switch, and they threw in a box-fan type LED as well with 216 1-watt SMD LEDs in a mix of warm and cool whites with additional reds that seems surprisingly decent. My gripe would be that each board only has 420 diodes, but they're very reasonably priced and have done a great job so far.
I would say that for a home grower the ~ 20% increase in efficiency of the lm301h diodes relative to lm301bs is not a big deal but for canopy penetration, heat control, lifespan, and decently competitive pricing I think SMD LEDs are preferable to those two chip diodes, with or without reflectors, and get better coverage than similarly priced COB LEDs.In your opinion, how much do the efficiencies really matter?

I grow for effect, I don't mind smaller yields, still learning about all the technicalities of the lights.
Thanks Joe for the detailed explanation, I'm understanding a bit more about all this light stuff.I would say that for a home grower the ~ 20% increase in efficiency of the lm301h diodes relative to lm301bs is not a big deal but for canopy penetration, heat control, lifespan, and decently competitive pricing I think SMD LEDs are preferable to those two chip diodes, with or without reflectors, and get better coverage than similarly priced COB LEDs.
Honestly that board looks good for the price; doesn't have much to dissipate heat, but says it's made with lm301b SMDs which are a nice brand-name diode for a home grower. By my count the QB2000 has 468 diodes, with 52 reds, and therefore 416 of the lm301bs. It's all 3000k, so better for flower than veg, but will do the job. The QB1000 isn't necessarily a bad deal either, it's 227 diodes per board, 26 reds, so 201 lm301bs. Two of them as opposed to a QB2000 would have 14 fewer lm301bs but cost 10 dollars less. You could move them around, but there would be two power cords.
I forget the last time that I counted a spider farm board but I remember that they have a lot of diodes; a SF-2000 has 288 lm301bs on each half for a total of 576 lm301bs in a mix of warm and cool white, plus 28 reds, and 2 IR; 606 diodes total. It costs twice as much as that QB2000, but you can see why people pay for it. It's a well known brand and they've got a good density of brand-name diodes.
There's tons of stuff you could put with it temperature meter, smart plug a WiFi camera, an intake fan to lower temps, you can view and do actions remotely.I was recommended this light, The GooingTop QB2000, supposedly almost as good as the Spider Farmer SF-2000, Samsung diodes and Meanwell driver, but with 240W for only $150.

Wattage is just a measurement of input, what you care about is output. The two-board setups like the SF 2000 are usually rated for a 2x4 area for flowering and a larger area for veg (possibly even the entire 3x5)Thanks Joe for the detailed explanation, I'm understanding a bit more about all this light stuff.
Do you think any of these variables would have a final effect on the effect of the flower smoked? Not potency or anything, but do you think one light might make the effect more "positive" over another one? Less paranoia? Stuff like that, I wonder.
I have 1 Mars 100W light already, if I added the spider 240W one, that would be 340W... that would only be enough for 2 plants no? Was hoping to grow 3 or maybe 4 plants each run. (I grow in my tiled shower, it's about 5'x3')
Agreed. SF aren't horrible. I've got two SF 1000's in my tent I'm using for veg currently. But for flower I'll switch out to my HLG 260's 3000ks. The HLG's are easy to upgrade which can't be said for the mars or Spiderfarmer's.How big of a space do you have?
You could also spend $15 more for the HLG that's built here in America. $315 after "RIU10" discount.

The other lights will work too, but HLG is top of the line for QB's. And for $15 more, why the hell not?
