You have over 600w majority is HID. on a 4x4 tray. He has 255 in a 3x3 which is less than 225 after drivers. Big diff. Your opinion isn't of much value until you finish your grow.
Whatever man! Your idea that he needs 3 x P450's in a 3ft area is stupid, whether you finish your next grow or not, that info isn't much value!!!
What are you talking about anyway? 4 x 4 tray? It's a 5ft x 5ft tent, not a 4ft x 4ft tent or tray.
You said he needs 3 x 450w leds in a 3ft x 3ft tent! Complete and utter bullshit! Sorry to offend you by disagreeing with you, I just couldn't stand the smell of fresh bullshit being spread round!
