This probably wouldn't be very hard to do... and I have no intention of doing it any time soon. I've had an idea that's been pottering about in my head for some time now... It involves a similar method to SCROG, but instead of using a mesh screen replacing this with a glass or plastic screen...

Would the screen work in the same way as a greenhouse?

Also, you would be able to get the plants closer to the lights as the screen would absorb most of the heat.

You been smoking again!?!?

I'm sorry but what do you mean by the screen working the same as a greenhouse?

By intensifying (concentrating) the artificial light... and yes, I take my medicine regularly... what can I say... I'm an addict.

I know that this probably makes sense to you but wtf?

At each of my grows, all my lights have glass covers. Without the glass the temp's rise incredibly. Instead of having seperate pieces of glass (plastic), i'm suggesting having 1 large sheet suspended 6" below the lights. The plants could grow to within an inch of the sheet without feeling the heat. So, they'll get maximum benefit from the light.

Ever used glass covers for your lights mogie?

Of course most people use glass covers. It was all the talk about a mesh screen that was confusing. Still don't know what that has to do with a glass cover for a light.

It was for imagery purposes... of course this screen will be solid. But it'd be suspended further below the lights than usual glass covers. Also the size of grow room I have in my imagery is 16ft x 12ft.

So, you have six 400w lamps suspended from beams that are screwed into either wall. You could get a plastic screen and suspend it from the beams, and below the lights at about 6". The heat from the lights is absorbed into the plastic and spread around, but the light still gets through as the plastic is translucent.

I'm not too clued up on greenhouses which is why I asked the question.

Oh that is what messed me up the imagery part..That part of my brain is not working at the moment due to over use of marijuana.

Honestly? I haven't written for 3 years due to having kids but I find that all my best ideas come when I am stoned... my imagination goes into overdrive.
