I know you've seen this pic in my log, My dispensary owner buddys SCROG, he's using 600's but 1000s would work fine, just space em out more.

Those are 5 gallon grow bags under the screen, the screen is 3' wide I believe. 2 rows of plants per table, tables are about 20' long and fit about 30 plants.. You could get away with a 4' wide table under a 1000.



7 plants per 4x6 screen will get crowded quick but there's no reason it won't work depending on how big the girls are.



Good luck, just tossing my $.02 out there.
