awesome journal! brilliant grow!

"I tied up all the holes except for one.. making a vacum effect, meaning that the air is extracted without need of a venti that extracts it.."
thats f***ing brilliant. No less that a major break through in the science of venting grow tents!
let me get this straight - u have a 400 hps in a cooltube - in a 60x60x140 tent - and without a fan(!!!!) u are keeping temps down...??!!
how do u go about sealing the intake/outake holes off?
I am very courious about this - i just got my darkroom - thinking i was gonna use it just for veg - i hate the sound of noisy fans (got one in my pc, one in my xbox, one in my kitchen - that will have to do.)
then i read ur journal - enlightment big time!
. I know you said no LST or anything but I really recommend tying down that central cola of yours, tie a string to the main branch and pull it down to however low u want it, this will allow you to lower ur lamp a lot and in the end your yield will be much much bigger by allowing those nice nugs at the middle level of the plant to become massive as well. Also tying down the main branch doesn't really stress the plant at all since your not breaking or damaging it at all. Ive had great success with this method.
