What Size Smart Pots To Fit 10 Plants In 3X3 Table?

[Sweetgreen]

I have 10 seedlings and would like to be able to fit them all on a 3x3 table. I want to sex them as early as I can, kill the males and then turn the remaining females into moms.

What size Smart pots should I use so I can fit 10 on a 3x3 table, but then also allow enough room to grow into moms? I'm hoping to take up to 10 clones off each mom in time for summer.

They will be under a 600w

Thanks
