4 1000s or 6 600s

I am doing an aeroponics grow with the aeroflo 60 as well as the 60 extension. Im going to flower directly from root and lolipop them as they grow. Plants wont get more the 2.5 feet tall with pure indica purple strain. You think I will benefit more with 4 lumnatek digi 1000s or 6 lumatek digi 600s. . I think that with the 600s I will have more coverage and I will be able to put them only inches above the tops. Either way it will be aircooled. Please give educated advice. Thanks.

If you think your getting them inches away you need to do a LOT more research before buying 5k worth of digital HID lighting. 600s are more efficient if you could have all parts of all plants the same distance to the lights, but you cant, so thats why most people use 1000w lights to get deeper penetration and more bigger denser buds.

Also a pure purple indica strain is gonna be one of the lowest yielding strains you can find, and a waste of time if not grown right, although if done right can be amazing in quality.

As far as coverage, if you go with 1000w lights you will get better penetration and if you use light movers you will get a huge coverage area.
