Nutrient film technique rail system
Aloha,
So my space is very small. I tried using 4" downspouts , it cannot be cleaned good enough. So after checking some premade systems. I decided to make my own.
I chose 5" vinyl fence posts. The plus is the endcaps. Since they need to be able to be cleaned, I cut them lenthwise. Put some 2 5/8 holes on the topside and 1" drainholes.
Here is what it looks like
