let me ask u this where did u get the rr's at?? were they that size or are they the ones from home depot/walmart type where there compressed and u have to soak them in water?? if there the compressed ones then i know what ur talking about there junk and i don't like them i use the real peat moss rr from gh but i've noticed the compressed ones stays to wet or too dry u can't seem to get them just right.other than that ur set up looks fine i was thinking u had the 5inch net pots but the drip line looks fine where they are to me
