Yield Calculator

This is pretty interesting....says I'll get 3oz off a 150HPS. Not sure how close, but seems one of the best ways to guestimate.

Its calculating off of canopy sq ft meaning that you will have several plants in that space and the max yield it can produce.

Cool calc though

lmfao, stupidest thing ever.... it told me that i would get more with less lumens per sq ft than i would have with a higher amount of lumens per sq ft..... i got a yield calc for ya.... grow 5 crops of the same strain under the same conditions and calculate the average grams per crop... then you know what to expect... other than that eerything is a crap shoot man...

not accurate but something to look at i guess
