The Origin Large Wide 8 Pot System 8x 18L is a dripper irrigation watering system that is suitable for use with any media. Origin Systems have always been a popular choice for growing for their ease of use and low power consumption. Bring your plants on so they are a suitable size for the pot and then transplant them using the substrate of your choice. Place the pots in the recesses on the top of the system and rig up the dripper system. With a dripper in each pot, the pump delivers water and nutrients when you switch it on. For even more convenience, a segment timer will switch the pump on and off as you want.
