Ive run 18 SLH in a 4 x 8 like you have, got tight at the end but pulled it off. Making a trellis was essential though.
I got the Jardin DR240. Excellent buy with no complaints aside from the carry bag which could be a bit thicker material. I also really like how may options for ducting, electrics and irrigation etc it has. There is also a removable floor that has velcro fasteners which is very handy.
