Wanting to water hanging plant and planter with 4 shrubs. I thought I could just run 4 way manifold in planter and use 1/4" tube cut off at each shrub. Also planned same simple arrangement to run 1/4" tube up to hanging plant. Now I wonder if I will get enough water to plants. Was told they need to run on a longer timed circuit than the 10 minutes I normaly run my circuits. Can I run a line from each of my two circuits and get 20 minutes to be adequate? How long are the timed intervals typically? It just seems things are getting complicated.

Thanks Greg
