How many plants in a 4x4

How many plants would be ideal for a 4X4 tent using scrog?

If I could go back in time and restart I'd do 2 maybe 3 of the same strain. Veg for 6-8 weeks

I would go with 2 if scrog-ing in 3 gal to 5 gal pots with a longer veg

2 to 3 of same strain, less issues, all can take same nutes and what not, but use a unit that can hold the weight!

Or vertical then 8.
