18/6 is what I’d recommend and power draw is all that matters the bs fake numbers they knowingly lie about are the ones you are hoping them to be but trust me you would need 8 plus of those in a 4x8 to flower imo,

What about a 3kw LED panel?

Spider farmer does grow nice buds honestly seen it first hand. Not a bad entry choice from tiny clone to 3/4 ounce in half gal of soil and 72 days (mostly done just to test light I don’t normally flower plants this little first pic is day 1 of 12/12 for that clone

For autos I run 20/4 you can run them 24/7 but I find they still need a bit of a break, you also don't want to be running soil, autos prefer light airy medium, promix line is great..I run the bx..lots of people run the hp both very similar hp has more perlite, you'll also need a good nutrient line, because either of these only have mychorhaze in it..so you'll need to fees them...also 10 plants is gonna be alot of watering. One of my autos on avg is drinking 3l every 48 hrs...if yours run the same your looking at 30l every 48hrs..thats alot of water ..which you'll see is gonna be a big pain in your ass, these are bruce bannera under a sf2000 using the things I mentioned

Same it would only matter what the real power draw is and most times if a company says 2000w led its real power draw is way less less than a quarter of that probably

You get what you pay for, if you want to cover a 4x4 area you are going to spend upwards of 1000, actually maybe you can get a good quality light for 800 but I'd really look into the company, look at them as 10 year investment. 600 or more watts for a 4x4 750 w is top light saturation power from what I can figure out. Hope this helps and remember this is only my opinion, everybody has one.Anyone know who makes these? Led detail.
How does it compare?

So I just looked at the sf-1000, and the specs on that say it is only 100w power draw. Going by what you guys have previously said, that would mean that light is weaker than just one of the 600w that I already have at 125w draw. That's why I was saying earlier that draw is not necessarily equivalent to output.

My sf2000 is equal to around 600hps

No it’s not equal but spider farmer is using good top bin diodes made by Samsung your light is using old tech and no good chips you have 60 led chips in your light while the spider farmer has somewhere near 200 leds. Again you get what you pay for and you got some ok clone and seedling lights. They will not get you through flower with 8-10 plants and I guarantee that

No it’s not maybe 400 not 600
So what if I were to add a sf-2000 along with the 2 600w I already have?

Still not enough light for a 4x8 if you added that light you’d have enough for a 4x4 but only hardly

Look up ppf (same as umol/s), ppfd (ppf divided by area) and dli (plant light need per day) If you understand those you will know what kind of light you need. There really isn't much more to it.

2 4000s would probably get you where you need to be

If I were going that route with spiderfarmer I’d pick 4 sf2000 actually just for better light spread but if spending that kind of money diy led might be the better choice. But also I’m sure you could get a company like sf to discount the price if you bought 4 at the same time

Even 400 seems high though a grower with decent experience not even a great grower can land a lb off a 400w you’d have to be a pretty good grower to pull that from the 200w panel

And with the new sf200s you can daisy chain them, if my wife would let me id go with hlg550s but she'd kill me if I bough a couple of those lol
