Will a SF2000 adequately flower a 3x3x72 tent?
That’s 22 watts per square foot. I think you should be shooting for 50 ish watts per square foot you would need 2 of them to be close to that, somebody else may say different I have no idea how efficient spider farmer lights are
How bout for 2 Autoflower?
Should be okay for 2 autos as long as they don’t get massive.
Would the HLG 260W QB V2 RSPEC kit be a huge upgrade?
Yea its quite a bit better even though the par is similar the increase in red spectrum makes a big difference in flower . Personally I like the xl version its 2.75 ft wide and gets the edges really nice and gets a more even spread( and if you ever want to upgrade it to a 3 board you just need 1 more QB 288 and a better driver)
I have a buddy who runs 2 marshydros ts 1000s in a 3x3. they pull 300 watt altogether and he has great results. looking at the sf2000 specs I bet you would be fine. they are very close
Gonna return the SF2000 and pick up a HLG 260W V2 Rspec…for the same $$$🤑
I think the qb 260 kit is superior light, but the sf would probably do fine
Would 2 135w kits give more versatility than 1 260w? I’m gonna return the SF2000 and trying to save a little money. Prolly won’t be totally satisfied with the results but could add another 135w later. Trying to get it right…
Probably. Will depend on what you’re doing and how much flexibility is needed. With two separate fixtures you can move and dim them independently if need be.
