Question about Gardena NatureUp!

I have 2 small hoses connected to the pump and use them to water about 10 planters

Yes, there are hose extensions, couplings, nozzles, etc. I have about 35 drip nozzles attached for about 20 pots on the balcony and a €0l rainwater barrel as a source.

There is plenty of hose that comes with the set. Otherwise, if not enough you can always buy single items from a home supplier who offers Gardena products. I used this watering system on my porch with three plants several meters apart from each other. All together I used about 10 m of hose.

Forget it, it's absolute rubbish, already junked !
