The hose in the box is 20m long.
There are 20 drippers at 2l/h and 10 drippers at 0.5l/h in all.
You can programme waterings of 5min, 10min, 15min, 20min, 30min.
You can decide whether you want to water every 12 hours, every 24 hours or every 48 hours.
Each combination will give you different basic tank requirements if you want to last 2 weeks.

The constraints are to use at least 10 drippers of 2l/h to avoid overpressure and you can use a maximum of 20 drippers at 2l/h and 10 drippers at 0.5l/h.

The hose is long enough... still have plenty of hose... You need a water cistern with at least 100 litres then it should be enough... this is the big system... how many plants do you have? For the small system there are 10litre tanks... I find them too small, but for two or three plants it might be enough

I also use drippers with a higher flow rate than 2 litres and more than 20 pieces. Works tiptop.
