Ok can't seem to get an answer to this question!!? You take PVC, drill holes of some size? support it outside of your PVC fence tubes where the plants will go, drill a hole inbetween each net pot spot, size? but the real question is what tube do you use to go from the feed PVC line to the grow tubes??? How do you secure it in the feed line so it wont leak and then how do you put sprayers and what kind, size, in them inside the grow tubes. I have seen many pictures of the set ups but no close ups of the connections or specifics on items needed to get the connections done. Thanks for your expert advice. IF you wish to direct me to a link please be specific and not just a photo of the set up because like I said have seen the photos, Once again need the details on hole sizes and gromets if you use gromets, size ect ect ect...... Worried about that type of set up leaking. I have feed lines inside but want to change them to top and from outside. I think that is clear. Thanks...

Remember its friday just wate until tommorow and you might get some answers

I use 1/4 inch inside diameter grommets in the channel. On the sprayline i use 1/4 inch i.d. instant fit tees. This way it feeds two channels at the same time.
