5x9 Gorilla Tent with 2 Blackdog LED 600s

Any recommendations for medium? Objective is to scale quickly with highest quality, low volume perpetual harvests. Inline fans and dehumidifier along with rotary fans included in this new setup. I've got 7' of clear height so I can't use the Tent extender. Targeting the most organic/sustainable of products for the grow and intend to run two to three strains - Haze Berry, OG Kush and Jack Herer to kick it off.

Thanks for any comments and suggestions. Your counsel if much appreciated.

All of the above named seeds are Fems
