Sf4000

[Ryguy]

Growing 2 ak-47 in soil the rest is zkittlez in a 5x5 under a sf4000. Started 12/12 a few days ago. I wanted to see the different yields at different heights. Is this to many for this light? Should I put my 600 hps next to it?
just looking for advice.

It specs a 4x4 for flowering.
I don't use that exact fixture, but my QB fixture is almost identical to it.
I run it 20" @ 50% power during veg and 20" @ 100% during flower.
Almost all of the plants I run indoors occupy a 2x2 footprint, so I'd say you should have plenty of light to fill a 4x4 canopy.
Time to practice your trellis skills...

The sf4000 is plenty of light for what you are growing in your tent right now, wall to wall corner to corner probably not but how your tent is there should be plenty. Your plants look happy in there

Good luck with the plan, that's a nice light.
