Light questin(lumens and such)

[Weezard]

I am just curious but, how much lumens per plant would you say is a good amount. I have read that really 25,000-50,000 is good.

You have read right.

But you must define "per plant" in terms of area.
Prolly better to use square feet or meters.
And you need to be talking about full spectrum, (white), light.
The Tropical sun, at noon, exceeds 91K Lumens,per square (um, I forget), and that is too much for Cannabis.
