Can i vegg and flower in same "room"?

My room is 11' x 5'. I have plenty of space. Do i need a petition of some sort to block the lights from one side to another?

Yes. You'll need separate areas.

Yes, and no. You don't need to partition anything off if you don't plan to run crops perpetually with dedicated rooms for veg+flower. But if you want to be preparing the next batch while your current batch is flowering then you do need to partition the room into at least 2 spaces with separate air exchange/environmental controls to do it right.

what groerr said...or perhaps run autos instead (head over to the autoflowering section and make a pass through the thread titled "Autoflowers indoor - It really is that simple"

Stick a small tent in there for vegging.

My friend is using a medium size cabinet that is light proof and has four baby girls that just were super cropped to control the height until flowering is done in a couple weeks. he just installed inside the room that's flowering. He has a 10w warm LED to keep them smaller right now. He was thinking of adding a couple more possibly since he has them lying around. Once main lights come on, the babies go into the main room.
