Most plant leaves do their best with sunlight between 3,000 and 4,000 lumens per square foot. So the question is, how many light lumens do you need for indoor plant farms?

A standard 100w lightbulb will give you 1300 lumens.

question are you going to use led grow lights or the ones with the uhm,... gases...? unfortunatly I am having a mind block and I AM NOT going to search it up. need to focus on remembering something I know for sure.

anyways...

Here is a post from hightimes about light lumens. it is worth a read.
