They are actually specific hydroponic troughs that my local hydro store carries. $2 per meter. Also came with end caps, one set that are solid and 1 set that have a 1.5" drain hole at the end. If you were to look at them in profile they have a slight vee in them that moves the
nutrient to the center of the channel.
