Hi, will Grobo alert when to change H2O?
In flush you need tp drain and fill to get rid of the nutrients in the reservoir. Then unplug bottles 3 4 and 5
Good too know
(The Day Your Plant Reads Flush):…
I didn’t know you were supposed to unplug bottles 3-5 for the flush phase
You dont need to. Just drain and fill on day 1 of flush
Perfect thank you
