I have a vertical garden in my back patio & during the growing season it does pretty well.  Unless I’m out of town.  It always suffers greatly when I’m gone even 3-4 days . The hot sun dries them out.  This year I decided I would add a drip irrigation system.  Not only would it help with keeping the plants happy while gone but drip irrigation systems also help conserve water.

My video below describes my plan

What I bought to create my drip irrigation system:

2 xxAGSIVO Drip Irrigation Kits: https://smile.amazon.com/dp/B07NXZNCVX/ref=cm_sw_r_cp_apa_i_peHZCb253H0XD

2 x Rainbird 25psi pressure regulators: https://smile.amazon.com/dp/B0049C5FZA/ref=cm_sw_r_cp_apa_i_yfHZCbCTHFJJK

1 x Eley 3 way faucet splitter: https://smile.amazon.com/dp/B06X9X5MCY/ref=cm_sw_r_cp_apa_i_AgHZCbTR370BC

1 x hose shut off valve: https://smile.amazon.com/dp/B0786HP6J9/ref=cm_sw_r_cp_apa_i_fhHZCb296XRE9

I hope this helps you plan your own Urban Vertical drip irrigation system!
