Well, I ended up just buying a 3' x 3' tent and calling it a day. It was only 80.00 and it will stop my issues on this, and any future grow. I guess it's a good problem to have

outgrowing my space.
The problem started when I decided to only grow one plant at a time (that would have been fine) but then I decided to overlap so I could have harvests closer together...then after buying the AutoCobs and MegaCrop nutes, I guess I did better than I thought I'd do and my NL Auto got much bigger than I had anticipated after her less-than-impressive start. That's how I got here
So I guess I have GreenLeaf Nutes and BigSm0 to blame for costing me 80.00 more!
