Don't know if this would be remotely correct, but I think I might have stumbled upon a harvest calculation to give a rough guesstimate to your final weight at harvest. Of course everything depends on your strain, etc, this is most likely complete bullshit, but here goes.

Here's the formula:

Code: 
Approx Dry Weight *per M2  = 0.001 x watts x flower light period x days in flower
So an example would be:

Code: 
0.001 x 1000watts = 1 x 12 hours of light x 56 days = 672 grams (1.4 lbs) *per M2
Example 2:

Code: 
0.001 x 100watts = 1 x 12 hours of light x 56 days = 67.2 grams (2 Oz) *per M2
*A square metre is approximately 10.7 ft2

Thoughts?
