Plants under SCROG

I have 3,3 x 3,3ft grow space with 250W HPS, will setup SCROG (2,25 x 2,25ft) and grow Lemon Skunk. From SCROG topic found that 1 plant needs 1 sq ft, so my total of plants is 2? Correct me if I'm wrong.

2.25 x 2.25 is just over 5 sq ft so if you want to do 1 per sqft then you'll want 5. I would probably do 4 in that space for a SCROG grow. Put some pots in the space you want to use and do what seems right.

My grow is in a 4' x 4' Jardin tent and I'm using two plants to fill my screen. Details, pics and all that are in my thread, linked in my sig if ya want to take a look. A single plant can cover a much larger area than one square foot. Good scrog growers can fill 5' and more, easily. The trick is to train the plant to branch. It also needs to be in the correct sized pot to allow the roots to support it and the number of tops it will generate. AS you retrain the tops, more tops will form and your longest tops will grow to fill the outer portion of your screen. Many branches will form along it and they too will fill the screen and so on. Because you are forcing the plant to grow sideways, the hormones encourage all of the nodes to attempt to grow straight up, forming new growth tops that will become colas.

With a 2.5 x 2.5 screen set up, place a single plant in a 5 gal container in the center and work it for 30 days or so in veg. Flip to 12/12 when about 80% of the screen is full of tops. Continue to train for about another 7-10 days. The plant will quickly fill any remaining screen as it attempts to get direct light. This is when you go below the screen and prune all side growth off. Cut off all sucklings, fan leaves, small stems, everything that is not going to get light under the screen. This will allow the air to move freely, remove hiding spots for pests, and allow the plant to focus on the colas.

After all, we aren't growing for leaf....
