does everbody get massive yields with the mpb's?[/QUOTE
i keep hearing about big yeilds off mpb's too, i have just started experimenting alongside my normal methods. and once the roots get established in the nute solution they take off, but it seems to take a few weeks to get to this point and a soil grown clone after 3 weeks in soil is about four times as big as the bucket plant. also as Coxie said more lumens = more bud, and if you are running 16 x 1K i would expect to get about 18lb of bud just off soil without the expense of $1000's in chillers and other parafenalia, so in answer to your question, not if you have one plant under a 100 watt cfl
irrespective of all the kit and controls, you would get more off 1 plant in a 15ltr bucket of soil under a bigger lamp.
