I'd be most grateful for advice about setting up irrigation on my balcony, 1.8m x 2.2m. I'm in a tiny retirement unit and not permitted to instal or attach anything permanent. I have no outside tap. My watering can doesn't fit in the sink, it's a palaver to fill, heavy, and needs three trips. I found a hose connector which works, but the hose hangs off a hanger from the balcony rails - hard to wind, and it's a trip hazard too. I suspect there is no streamlined answer, but I've lived a Heath Robinson lifestyle for much of my 74 years, so I don't care how it looks, I just need a work-around! The kitchen sink is at the opposite end of the unit, 7m from the cat flap where any irrigation pipe will emerge! (I did say Heath Robinson!) Can I get away with using a smaller diameter pipe than 13mm (which I do realise is the best (and why) though we are talking only pots, which will need to run via drippers from the pipe). Many thanks in advance for any suggestions!
