This is a monster (6 feet LS). Phrag don't like me all that much but this is an exception. I grow it in a bark mix in a tiny (considering its size) plastic pot (5 inches). It sits in water most of the time. I give it RO water at (give or take)400 microsiemens (MSU fertilizer). It gets a lot of natural light (direct sun for 1 hour in the morning). It gets an occasional rinse in pure water. It was a sequential bloomer for 2 years with one bloom at a time and then this year, the spike branched off and I have 5 blooms open at the same time. It takes up a lot of room but it is very majestic.
