need to know

i want to have veg and flowering in the same room in two flood trays.
i want to know if i have to separate the two with a wall cause i have seen pics of peoples grow rooms and they dont have a wall up or they took it down to take the pic

Ur gonna have to separate em somehow unless ur gonna flower em all at the same time as well.

They definitely need seperation, when in 12/12 they are supposed to have 12 hours of complete darkness, not even a pinhole of light is acceptable. Doing that in a room with light on 24/7 is going to be a little tricky.

yea that def sucks a big one
