Is there such a thing as too much quantum?

[Buds.on.a.budget]

I've upgraded my 4x2 flowering tents lighting set up!
I'm now covering it with 4x QB 288 boards with a dimmer switch, according too my meter when turned up full it's pulling 550w.

So that would give me 68w per square foot.

Is this advisable? I know the recommended amount is around 35wpsf

I'm debuting this set up with my favourite strain, cream manderine f1 fast version. Meanwhile in the small veg cupboard (1.5'×2.5') I'll be sticking two "think big" autos with a QB 288 to each plant

I'm hoping to be able to keep on top of a diary with these grows, I started a diary before with an auto ultimate but let's not talk about that haha!

There’s is a point where there’s too much light regardless of the type used.68 watts a sqft is fine.

I knew there would be a limit at some point but wasn't sure if 68 would be okay, I can always dim it down to 35/40

I run my QBs in the 45 to 50 watt/ sq ft range with great results. I've seen people make it work as low as 25 and as high as 75, but for me, that 45 to 50 range seems to be the sweet spot. Good luck.

I’ve experienced burn at 40 watts per sq ft with my 320 XL. I’m at 35.

This is at 14” though. My lights can’t go any higher

This was my last run, hoping to beat This, double the amount of light this time round I'm currently vegging two clones from the pictured grow
