With the 4x4 cubes on the slabs How long do you water and how many times a day?
That changes as they root out and dry down...
3 feedings a day initially, upped from 2 in propagation, if measured we want 300ml a feeding
Due to limited space in veg, we up-pot on flower day 1 when done right.
Then as they eat more of their maximium media saturation volume, we up it to 6 -8 feedings a day at anywhere from 2 mins to 5 depending on the room/table
At week 2.5 the automated room is eating 5 times a day at a 1.5min ,besides an initial fertigation of 3 min. @1ml a second
