I bought these (they have pressure compensation) because I have pots/plants with more consumption and can regulate them more precisely than with the number of drippers.
Gardena Adjustable Row Dripper (Dripper)
(use the ones with approx. 1.5 to 2 times the flow as the supplied ones with fixed flow)
The original ones are also available individually.

these are included with the city Gardening (apparently without pressure compensation), I'll have to try them out to see if they are compatible with the aqua bloom.
the City has a pump directly in the bucket and only runs for a few minutes, and these 2l/h drippers are almost flowing,
while the blue ones on the aquabloom drip much slower - I don't know if that's because they are
I don't know if it's because they don't have pressure compensation, or if the city gardening pump is more powerful - the city definitely makes a lot more noise.
I'll have to connect a blue dripper to the City and the other way round connect this one to the aqua bloom and try it out.
Gardena Micro-Drip-System Row Drip (Distributor)

have bought these adjustable ones for city gardening: 0 - 10 l/h (without pressure compensation)
Gardena Row Drip (Row Drip)

at gardena: - not sure if the aqua bloom needs the one with pressure compensation,
or if the other ones work as well - maybe contact Gardena support
https://www.gardena.com/de...

the ones that come with the aqua bloom are these (https://www.gardena.de):
Polybag row dropper (20x)
Spare part no. 13300-20.703.00

if they are not available here, just go to the migros doit garden centre,
they have the whole range at the one in bern/wankdorf, including the blue ones.

You can also buy the row droppers individually.
