3000 PER SQUARE FOOT is the minimal reccomended. It all depends on how many plants and how big your space is. Lower amounts will work but you will need many more to get anything harvestable. Lots of light is required in the flowering stage.
i thought thats what we were talking about 3700psf and if thats so and thats 3700psf over a 13sqft area than that means each sqft is getting 3700L and 13 plants would rock
