The word “flush” can mean two things. It can mean to simply keep adding water to your plant until you have a low EC and have flushed all of the nutrients out of the soil/substrate. Or flush can mean simply starting the process of only adding plain water to your plant with no nutrients. The second option is what I do for my tent grows. For the Grobo, it stops adding nutrients as soon as it starts flush and only feeds the plant plain water.
