UPDATE:
Well the venting took quite a bit longer than i expected.. but after two days and several late night trips to the HD, venting is done.. for now..
the little one was transplanted a lot later than the others.
I'm in the process of sealing up the closet now, just taking my temps!
I decided to blow through the light because i couldn't fit the fan inbetween floors. I did however add a 6" inline duct fan on the other side of the light, so it's blowing and pulling through the light.
They got their first taste of 12 hours dark last night, and FINALLY i'm flowering!!
I highly recommend noobs, like myself, get things like this worked out ahead of time! Could have been flowering for weeks..
and now i'm broke as a joke with no gaunja to smoke
