3 X 600 hps = how much bud?

[blackone]

ok thanks blackone i get that now, but the light is still diminished on its way to the reflector by the inverse square law i would have thought. also i imagine it would be very hard to get perfect parabolic reflection in a prismic tunnel with a light source that only comes from one point or even 2 or 3 lights. basically what i am saying is that it would work in theory but almost inpossible to get it to work in practice!

Indeed you're right - it's a prism not a parabolic bowl. A grow tunnel is only parabolic in one dimension - so light will follow the inverse square law for the rays going towards the ends too. Still as long as the sides are also reflective I don't think it will matter much - as long as no light escapes it will still be confined within the growing area. Shallow angles with multiple reflections will of course take its toll.
Someone really has to do a computer calculation / simulation of this

you guys gave lost me right bout page 2...

take your time and this is probaly not the best page to start with, here we have two differing opiions on how to achive a yeield based goal one claims the other is bullshitting the rest is mostly good perpectives on how to maximise the use of light available, most of thses er arguement are based on using 2 600 wat lights on a light mover possibly three, oh yes one dude doe s not use a light mover and rekons he is better off, so to sum up you have avariety of opinions

He's probably smashing it now fella that was 6 years ago
