Firstly, please check that you have added the correct amount of water into the tray at setup. It should have been 550mL. Click here to watch the setup video.
We have tried to select seeds
with similar germination times but there are some varieties which are slightly
slower to start (especially during the colder temperatures)
The Rocket, Chia, Mizuna and Kale are fast germinating while the Pak Choi, Broccoli and Mustard may take a little longer. The Cress takes the longest at about 16-21 days. It's best to plant similar germinating varieties together.
If one side is not germinating as well, please leave the lid on a little longer for the weaker side to catch up. However, even if the lid is removed early, the slower side will eventually catch up given the right temperatures and sunlight.
