Hey buddy!
I literally just got finished beating my girls up! I started a Grow Journal if you’d like to catch up.
I honestly think Spider Farmer designed that tent for that combination! LOL!
As far as I can tell the sides don’t hit the light during negative pressure and I recently upgraded to the 6" Infinity exhaust.
I only got the 1 center support also. And the short cross bar, which I don’t think I use for anything.
I only have the exhaust hanging by the center support.
I got a cheap 4 pack of ratchet straps and use those, attached to the main outer frame for the lights.
They say a picture is worth a 1000 words…
Since I recently upgraded the exhaust I grabbed a screen shot of before and after for comparison.
Before
After
I LOVE my SF lights, but I have a HLG 350R arriving tomorrow! LOL!
I bought the 2.3x2.3 SF tent so I’m putting the 2000 in there for autos while I train and scrog a photo or two in the 2x4 over the long haul - and hopefully BIG haul!
Not sure if I’ll need the 1000 in the 2x4(doubtful) or use it to really blast the hell out of the autos as a side light or use for clones and seedlings.
Currently I’m using the small tent to force flower a couple of GDP that ended up in the same pot! LOL!
Let’s see what they do! Not expecting much 
I say go for it, it’s a great combination.
Happy Growing Everyone!
