The Ultimate Stealth Grow Cabinet?

So, I'm pretty happy with the Budget Stealth Grow Cab i have made, Its Cab that is very close to silent. Its Running a Tall Mountain Air Filter attached to a 4" Ebay FAN enclosed in a sealed and Sound Dead and Sound Absorbing material, all air passes though insulated ducking and also though a custom muffler and then finally though more insulated ducking out the window. (NO air whooshing and very little fan noise.)

HOWEVER I have questions about the lights. Im using a 600watt LED Mars Hydro Light, and the Cab "justs" fits another 300watt adjustable VEG/Bloom ViperSpectra LED with modification so thats a total of 900watt in a small CAB, i get that its basically under half 900 actual watts but is that to much light for a plant? Ill only be using the 600Watt LED + VEG lights on the 300watt to give it extra blue spectrum lighting and then the 600watt LED + Bloom Lights to give it extra red spectrum light when its flowering. Any ideas fam?

Attached are some photos.

Get the 900w thing out of your mind, your confusing your self. Its not a relevant figure. Combined at full power you have 406w.
Not sure on the size of your Cab but if temps are in range and plants aren't bleaching then your fine.

Also plants need less energy at the start of the grow. A two week old seedling probably only needs 25 w of energy. A mature flowering plant will need a hell of a lot more,

I'd swap the blurples for white LEDs, would be even stealthier and you'd get better results.
