Can you tell me do i need to buy fan on it and some kind of "ductingpipe"?
Peace Love and Big Crobs..

all cooltubes are is a aircooled light, most any hid lighting should have aircooled lights in enclosed areas
go to the place you bought your setup and they should have the cooltube, duct piping, and exhaust fans. while you are at it, it would be smart to also hook up a carbon filter for added security.
So i told that i have this problem should i buy cool tube, i got ventilation on this room. i made this space from sauna. it have pipe to getting air flowing in and one for out flowing.. :D it is really good space i wrapped all the walls with white plastic...
it depends on your situation, hid lighting produces lots of heat. lots and lots
yes white plastic should be fine
read from the links in my sig theres all the info you need on growing and these boards

What are you're temps like when your lights are on? Measure the temp where the top of the plants will be. If your temps are in the 75-80F range you don't need a cooltube but if your temps are 85-95F you need a cooltube.
ok.. i had window in that room too.. does the fans help to cool up room=? this is my first crob what i am going to grow and i need all the help i can get.. and i dont want to mess this up.. i bought feminized power plant seed and those are not cheap.. :(
And i am also asking that what kind of light cycle i need to give for mother plant and what kind of minium light it needs that i can take out the clones from it, when it is time to make second crob..
did you look at the link in my last post?
It works by pushing or pulling (preferably) air over the bulb to cool it. The bulb is enclosed in run of ducting. HID gets hot and you should plan on spending as much money on cooling as lighting. Some people just pass the air from the grow chamber over the light and out of the room, but it's best if you can have a dedicated intake for the light that comes from outside the grow room, somewhere close to the floor, and an exhaust to outside the grow room. Intake low and exhaust high, since the cooler air is lower.Quote:

This is the only place it should be used since it drastically increases drag (decreases air flow). Whenever possible be sure to use the smooth, actual ducting material available at home depot and hardware stores. It comes in 4 foot lengths and you can cut it with a hack saw or reciprocating saw. Also be sure to keep bends or elbows to a minimum since they too increase drag. A filter on the intake will increase the life of the fan, but will require a slightly bigger fan.
If at all possible be sure to overbuild in the ventilation department, so you don't have to tear apart your wall and start over like I did. There are formulas on the web to figure out exactly what you need for what you want, but I think most people just wing it. If interested search HVAC.
