Very sorry about the delay on the pumps / tutorial - what with the Raspberry Pi Pico launch, warehouse moves and various Covid/Brexit complications it’s been an incredibly busy time for us since the Grow launch!
The good news is that the software tweaks we’ve been waiting on to release the Grow auto-watering stuff are sorted now so we should be able to get the tutorial up and the tubes/pumps listed on the shop very soon - working on them now!
