Geez, did growing 'weed' come into  this?

I didn't intend it to be taken seriously.  In the immortal  words of 
Senator Claghorn "That's  a joke,  Son."  

A bit before my time, but wasn't Mr. Delmar's use of that phrase as  
Claghorn specifically to express his disdain for Northerners and a direct  
refutation of it being in fact, a 'joke'?

My suggestion of this indoor hydroponic 'booth' is specifically because  
they really CAN cut down on sound if they're placed  further inside a bigger 
room and not up against a wall. As long as  one adds a good thick base inside 
(carpeting?), and something on top  (thick  batting, perhaps?), the sound 
could even be prevented from  transmitting to the apartment (or room) above 
and below. The idea was to use  this as a starting base and with some 
ingenuity pad it out enough TO be used  as an improvised sound booth (which run 
into the $5,000 and up range  for anything close to this size).

The use of mass to prevent the transmission of sound is a  well-established 
acoustic principle.
The following is from _ 

and in your own site is a description of the 'sound curtains' I brought up  
however these are commercial products and obviously a lot more expensive  
than those I referred to. I've been discussing residential products on a far  
smaller scale as it relates to harmonica players who live in apartments. 
You  might want to look at this company's products instead:
those who've ordered them give rave reviews about the sound proof booths  
they've bought for mostly in-home, school, or small-scale  commercial 
Since most people can ill afford $5,000+ for in home use however, there are 
 ways to buy similar materials to outfit a purchased 'booth'. 
Some do-it-yourself methods:

Mass, or weight, blocks noise from traveling from one  area to another.  
Light, porous, open celled materials are  excellent acoustical absorbers which 
turn sound energy into heat  energy.  Thus reducing the sound from being 
reflected  back.  Good sound containment uses both of these _materials_ 
(  in  conjunction to reduce the sound 
levels in an area and block the  noise from  escaping.
Even if augmented by curtains, batting, or other light materials,  the 
performance of hydroponic tents  to contain sound will be  disappointing.


Have you actually done any test of this in order to make this claim? Not  
statistics but hands-on use in-house? I've had some success via use of other  
materials although I haven't yet tried one of these booths. At this point I 
 don't need to as previously mentioned and merely suggested it as a 
possibility  for someone in that position to experiment with.
Note that I didn't describe regular fabric curtains or any 'light  weight 
materials' per se, but specifically mentioned 'sound-proofing'  curtains:
and the batting made FOR that purpose since they're something else entirely 
 and could relatively easily be attached to the light-weight frame of a  
hydroponic 'room'. The idea was for simplicity, ease of dismantling and cost  
effectiveness, not to turn it into a far too expensive project. I've been a  
do-it-yourselfer since my teens and can imagine all sorts of ways to help 
cut  down on or soundproof a rental property.

There are many newer products being made to address this continuing problem 
 for those who live in apartments/condos/co-ops. While your theory is 
basically  correct (albeit a bit old-fashioned), companies have developed and are 
 constantly coming up with newer systems to address this very problem. 
No need for negativity about newer possibilities and experimentation.
