In theory, yes. It is important to use seeds supported by the UrbiGo device, ie spices and selected types of mini vegetables. If you plant different seeds in all 4 UrbiGo capsules, it can happen that each plant grows at a different rate - some will grow large while the rest may be still on the "baby plant" level. If you want to try this, we suggest you contact us at support@urbigo.me se we can suggest you some of the combinations of plants that grow at the same or similar pace, in order to get the best results. We do not currently ship 4 different plants with the UrbiGo starter pack.
