Yield Calculators and Watts/sq ft Chart

Heyy RIU


Just been searching around the net and came across this. Pretty neat!

HPS Yield Calculator

MH Yield Calculator



This was really interesting to read too, is it accurate?

Watts/Sq Ft Needed To Produce The Available Lumens/Sq Ft

Cheers

interesting, thanks.

Any idea if its accurate? Cause it told me I would grow 9 oz with 400w HPS and a few CFLS!

I do not harvest all at once but I flower 6 plants and depending on the strain get 36-56g per plant without the cfls. So it is at least close, though if you play with the lumens, your yield increases as you reduce lumens. Though this increases the sqft of canopy, I think the calculator is off in this area. Also if you use a 400w and decrease the lumens to 4000 you get a canopy of 12sqft and the highest yield for a 400w. Maybe with a mover this is true?

Very Interesting comment


Or mabe it's only for like SOG method or something. Who knows!
