^^^^Thats how my plant looked in its 3rd-4th week of flower, now I'm not saying don't scrog, I'm just telling you that if its too much trouble for you to make a screen then you can still get a nice even canopy without doing an actual scrog. The reason I didn't use a screen is because I have my bucket in another bucked to catch runoff, so if I did a scrog it would be very difficult for me to take all the branches out of the screen, empty the runoff, then put them all back in the same spot, imagine me doing that 3-4 times a week. So if you have your room setup where you don't have to move your plants, then a scrog would be a great idea, but, if your like me and you have to move your plants to empty runoff or for something else, then its not a good idea to use a screen because you don't want to go through the trouble of moving every single branch out of the holes then you have to put them all back in the same spot.
So either scrog or do what I did, and I think 2 plants would be perfect for the size of your space, I would veg for 3-5 wks, depending on strain, just make sure you don't veg too long because during the bloom stretch they can easily overcrowd that space.
As for the sog technique that someone said use 1 plant per sq.ft., I wouldn't recommend doing it the way he said, "veg for 2-4 wks", I would veg 2 weeks MAX and that technique is alot more effective when growing with clones. He also said you can easily get over a lb., well, thats true only if you got the right strain, all your other factors are dialed in and your using clones and there in hydro, not soil. If you are using soil and growing from seeds, then the scrog, or topping and tieing the way I do, would be your best bet, not sog.
Give us a lil more info on your setup so we can help you make the right decision, but only if you didn't started already, good luck.
