When using a segmental timer with a timed grow system the minimum feed can only be set to 15 minutes. 

When using the Imperium controller however, a larger number of shorter feeds can be set, for example: instead of 15 minutes twice a day you can feed for 5 minutes 6 times a day, or 2 minutes 15 times a day (pairing with a segmental timer is needed for this). This means that your plants won’t have to wait so long between feeds and will have oxygen refreshed 6x or 15x per day instead of 2x per day.  This action of getting more oxygen to the roots will promote healthier plants with bigger harvests.

The Imperium Timer has a simple push-button control. LEDs illuminate to let you know when you’ve switched from minutes to seconds and vice versa, while also indicating when the power is on and the feed pump is engaged. The timer will engage every time it is turned on, so the number of irrigation events can be determined by how many 'on / off' cycles you choose to create with your segmental timer, with the Imperium Timer regulating how long each irrigation event lasts for.
