    Hey Josh!

    I’m using a few autopots with a high-frequency fertigation schedule and I’m curious if my plants being in a tray their whole lives without drainage will cause salt build up over time. I only give them water mixed with solution at a relatively low EC. If I manage nutrient feeding correctly will there be any need to flush the system occasionally?

    Hi …… the salt build up occurs in the top 1-2cm of the pot so there is no effective salt build up that will affect the roots…… you should also never pour solution into the pot or you will wash the salts into the root zone…. this should only be carried out in emergencies if you have a lock out issue….

    Regards

    Josh
