lighting question

I have a grow bow that has an area of 4ft x 8ft x 5 ft tall, I've painted the inside w/ Flat white latex and am usuing 2- 150 HPS (1 on each end)Bronze High Pressure Sodium Mini Flood Light and 7- 4ft 2tube FL's (3 on each side(vertical mount) and 1 hanging at the top/center) w/ 40w hortilux tubes.

Is this enough light?

what ive learned more is better... Never too much light, never too much fresh air ... its all about heat, i strive to maintain 74-78 at night my room gets 66
5 feet high is very small cubic feet area

I know HVAC so I got the temps to 78 lights on and 72 off hovering at 45% himid also

That high pressure sodium is listed for outdoor use. Venting is a MUST. In most cases you can't have too much light.

I installed 2- 50cfm vent fans in the box and ran them to an outside vent and added a fresh air intake.

My question was is this enough light for the area?
