I live in Oklahoma and i'm running a similar system. I used four 4' lengths of gutter on a 6'x 50" wood frame. I also found it difficult to water after 2 weeks of growth so i ran a length of schedule 40 pvc along the back of the gutter for easier watering. I've been growing black seeded simpson well in my indoor rack and simpson select on my outdoor rack.
