so he needs to get at least an ounce from each of 5 plants to be considered a success?.....can't see that happening with the amount of CFL's he has.....
i would not view it as how much per plant , but how much in the space and light he has, some plants may yield more than others
so its pretty pointless working it out "per plant"
if you think he would yield less than 5 oz from almost 500w of light i would consider this wasteful of power and not a success IMO
and you are underestimating what CFL can do, also he has a 180w led, these combined lights i would suggest is going to give him atleast the equilivlent of a 400w hps
which can easy yield 15 oz if you know what you are doing, he has almost 1m2 of space
but IMHO he will be a success with whatever amount he harvests
if he yields 1 gram it will be a success LOL?
5 oz from 480 watts is something like 0.3 grams per watt if you cant acheive this, i would suggest a re-design
since much higher yields can be achieved than 0.3 grams per watt
i believe it is possible to be realistic and encouraging at the same time, rather than patronizing someone by telling them any yield is a success
that's the way folk speak to children to encourage them , i believe adults deserve more of the truth than sugar coated white lies
peace
