it took awhile for me to get my seeds from the uk, but i got them. idk about your light problems, it seems like you might need a a/c to cool them down idk if fans will work. as long as you have a/c in that room fans should work though. if it's just a hot ass room then hell nah.
Thanks jiggsaw, but I have an AC unit. I live in a 12x24 (U.S. feet... this is an international site so dont know where your from) log cabin with a window AC unit. It does great cooling the house for my comfort, however the grow box is more suitable for fried eggs then Master Kush. Running the 160cfm fan through the 6" ducting only reduced the temps by about 10 degrees (from running the same light in the unventilated box before the fan arrived today). Granted I am in the US Southeast in July where the current outside temp is about 90 degrees with near 100% humidity (its freakin HOT!), but I would like to grow my ladies year-round not just in the un-human temps the summertime US Southeast can provide. (BTW I hope your right about the seeds... I'm getting a bit worried.)Quote:

Well it helped... dropped the temp down to 90. I guess thats as good as its gonna get. I put a couple fans in there too. I went ahead and put the 4 bagseed plants (they are 33 days into flower) under the new 600w. They were under a 150w, not sure if the extra light will help in this stage or not, but we'll see.

one of the biggest problems you have going is there is no exhaust other than for the light itself, the box is going to need a fan pumping out the heat the light is throwing off otherwise the box will become a oven, theres 2 things you can do to make it work more efficient.
i saw you had a 90 degree angle duct, on the outside of your grow cab place that facing upwards on the vent that pushes the hot air out, forcing the air upwards keeps it from re-entering so you dont keep recirculating hot air.
this next step is up to you, theres 2 options, the 2nd option is far easier, but option one works well too.
disconnect the vent from the cab that lets in the fresh air, remove that end from the cool tube as well, we are leaving the end of the tube open so air from the inside of the cab gets removed as its stale air as it stands now, cut 4" hole at the bottom of one of the walls opposite the out-take vent, this is your new air in-take.
air now flows from the bottom side of the cab into the chamber then exits out the cool tube thus exchanging all the air inside the unit keeping it much cooler and running more efficient.
OPTION 2
simply add a out-take fan in the middle on the back wall of the cab slightly below the light, the radiant heat from the light can now escape the cab keeping it cooler.
Thanks but I dont think you have read the entire post (no worries, I'm guilty of posting while drunk too. :cool: ). I have already put the cooltube fan inside the box and there is already a vent in the back. As I said, doing that dropped the temps 10 degrees. I was thinking about doing what you suggested... dropping the fan from the inside top of the box to about halfway down (under the light) about canopy level. I think that might drop the temps even more. I dont want to cut more holes for fans if I dont have to... the lower the light bill the better. Also trying to keep it as light proof as possible (trying to stay stealthy). As it is right now there is no visible light during daylight hours and its only a slight leak reflecting off the back wall at night.
Well I ordered the seeds from Attitude July 18th, they got to New York on the 21st, sat there till the 31st, and arrived at my house TODAY! :thumbsup: Mes a happy camper! lol. Put the two Blue Widows in the paper towel zip lock, but when I gently squeezed them to check them out, one sounded like it cracked. You think it will still germinate?

Well I got some good news and some bad news... The bad news is of the two Blue Widow seeds, only one germinated. The good news is... one germinated! lol (see pic below)
Because I planned on putting two plants in the new box I started to germinate the other feminized freebie seed... the Blue Hash.
