You can start with 15 on every 2 hours but as it gets bigger you may need to increase the nutrients availably to the plant
Zandor Reviewed by Zandor on . How long to run drip system I have a homebuilt drip system. It consists of a large rubbermade with holes cut in the lid for 8 net pots. There is a submerged fountain pump inside the rubbermade that pumps up to each of the pots. How long should I run this mother? Right now it is runnning for 15 minutes every hour. Keep in mind that I am limited to only 15+ minute intervals as thats all my timer allows. Right now the plants are pretty small. Rating: 5
