Big Bud -yields

yo dudes i gt a lil pickle need some help with.

im trying to predict soley by figures given to me what my yield should / could be from 10 plants of "Big Bud" strain.
ive had like a million arguements with people saying i chat shit and blah blah blah etc etc.

if half of the seeds are female you should get 10-20 oz

its an uneducated guess at best .. it depends what lights you use, how you top and prune your plants and how many females you get. Its completely circumstantial, and if one of your first grows, arent going to produce like an experienced grower

just figure on 2 1/2 oz dryied per plant and you won't go wrong.then when you end up with more then that wellbe a great thing. good luck. with my big bud i grow i get any where from 5 oz to one lbs per plant. wth a 1000wtt hps though

i got the place covered in reflectagrow sheetin, use 2 x 1000w lamps and change from mh to hps when i veg (normally veg for at least 6weeks) humidy at a constant 30% except during harvest. use standard nutes and bloom elixers, temp is always 68degrees, and i aid growth with special supports for the plant. i knwo what i get each crop but im lost on the maths. apparantly its supposed to be 1.2g/per watt for big bud...but is that per plant or per m2? im lost in the maths. i just want to set a bar as being average and keep an eye on where i am and how to improve. i only buy feminized seeds ad have never cloned. my shed is 8ft(l) by 10ft(w) by 6ft(h) any predictions for what i should be pullin? im gettin quite a lot each crop but would be nice to know how good i am. this all came about because people in the chatroom called me a liar when i told them how much i get off a crop lol. ive tried the maths and just get lost as i dont know weather its per plant or per m2
