Pitching a tent.. Grow tent that is

Random title, yes.. Im looking at 4 by 4 tents, and Its not telling me the size of the vent holes on the majority of them. I need one with 6" to fit all the ducting i already have. Any suggestions on reasonably priced tents with 6" vent holes?

Peace in the middle east..

i dont know about any 4*4 tents but i have a brand new secret jardin dr40 (dark room dr40) for sale for $60 thats never been used. from what i see it says it has a 5" vent hole that can be easily cut slightly to fit your 6". i know this is smaller than the 4*4 but it could be used and saves some money as im selling it new for cheaper than wat i got it for and no shipping cost.

I have a 4x4 HydroHut and a SJ DR150, both have 6'' ducting ports! The HH has about 3 times the amount of ducting ports of the Secret Jardin! I like them both!
