Hi @lowrisk, welcome to the Click and Grow community.
Here’s a smart garden 9 set up video. As you can see it is meant to be used with one pair of arms from the start and all plants in the selection can be grown at the same time. You can read some basic info for every plant pod on the website or download the app and once you register your garden and plant pods you’ll receive timed tips for each plant.
A few things to keep in mind for best results are, make sure all plant pods would receive enough light, harvest your edibles once they are thriving and every plant pod has its last up to date.
