I would give each plant 7 to 8 inchs of space to grow in. I would use one HPS and one MH. A 400 watt is good for 4 square feet of primary light. A 600 is like 5.5 feet. Think light tracks. I would line the edges with soil so you dont waste light untill you get more sites.

karmaxul Reviewed by karmaxul on . HELP ME PLEASE. I was wandering about how big I should make the holes in this system I am putting together. The slab tray is 8inches wide 42inches long and 4 inches deep. I am setting up an aeroponics system. How many plants should I put on each tray. I might use the SOG method or I might just let them grow. Oh yeah what do you think of this light http://4hydroponics.com/clone/sunleavessatellite4.asp Thank you ahead of time for the help Rating: 5
