My well delivers 6.5 - 6.8.... I use it exclusively... always start in promix.... ALWAYS... and transplant around same time griever does... before roots get rootbound...
for example... Russian Dragon just got transplanted last night at 18 days from seed drop... they were already hitting the bottom of a 24 oz 7 inch deep cup... and had begun lateral travel.... another 3 days theyd be "rootbound" enough to stunt overall growth...
I am in bigger 32 oz cups time.(18oz last time) Two of them hit the bottom after one week and they are over two weeks now(the DDs), about the time they started taking a turn negatively. But I see people grow much longer and bigger in cups even smaller and never have problems.
