i wasnt to justifying my mistakes i am asking for reasoning behind what you have said, im sorry but if im going to be told something is true then id have to have a reason why it is true to fully believe in it, im not going to just blindly follow it.

Im not saying ur wrong and i never have, i just want to know why your opinion conflicts with the author of the book so that i better understand.

and it was you who gave me an example involving maths!
you need 40watts per sq ft
i just tried to use the guideline u gave me, now my setup didnt add to enough light on your scale so its fair enough im left wondering why the bridge between the two seemingly common guidelines are so different.


a wise man learns from his mistakes
a wiser man learns from others

i dont want to make mistakes when i dont have to through a bit of knowledge.
