Lumen Tester readings

[knowledge]

I was looking to see if anybody has info on what amount of lumens I should be looking for with a 1000w hps.

Not 140,000 either, I am looking for what amount to look for if I am using a lumen tester to properly arrange everything with the space I have.

And if anyone knows the lumens preffered by clones, I have read that clones do not need intense light.

Thanks

No takers?? Everything seems fine anyways. I am just looking to remove a light if I can for the summer. So I want to maximize my lumens with the remaining light on the space that i have to work with.

If anybody didn't already know.

I found a few sites stating that most plants will achieve their maximum growth rate before 5000 lumens. But anything over 3300 lumens on a leaf surface should suffice. I imagine that having all other limiting factors maximized, would allow for higher rates of photosynthesis, but I could not find conclusive evidence for cannabis, or the types of plants used to get these stats.
