you should not put others at risk without their knowledge. This goes
for your wife, kids, parents, live-ins or roomates. When LEO busts a
grow, usually everybody goes to jail.
Next, make sure your space is secure. That means either lockable or hidden. You don't want the Orkin man finding your grow room.
Your grow space needs to have adequate ventilation and electrical
resources for the size grow you intend on having. If you can't vent to
outside of the space or you have 15 amp circuit that the tv is also on,
don't look to put a 1000w hps on a mover in there.
Closets can make really good grow spaces, but heat usually is a big issue.
There used to be a site put up by a guy named Iguana who described
coming home from work one day and smelling growing bud from his
driveway. Have a plan for dealing with smell in place before the
terpines become pronounced. A good ozone generator can remove the odor
from the room and the exhaust.
Chests of drawers or dressers have too little space or ventilation
opportunities to house a big (400w or bigger) HID. If you need to use a
dresser, consider a small HID or flourescents.
If you have a big light in a small space, you will need big fans to
keep it cool. Big fans make noise. Make sure that the noise from your
grow doesn't tip people off as to what you are doing.
