I do still flush even with the rain mix. That's not because I seem to need it, but because I'm following Ray's advice. I thought (I might have got this wrong) that he flushes with MSU and as rain mix says it's the same as MSU I still flush. Surely whatever you use and however weak it is, it could still build up over time 
I know Ray does not flush with S/H because the water flow through the pot when watering means you don't need to. My greenhouse orchids tend to get water poured through rather than soaked like the indoor ones, so maybe that is what makes a difference
I find this really interesting, I'm doing what has worked for me but maybe when pouring through it would not need flushing... not sure. |
Rain mix feed strength recommendations are not the same as MSU recommendations, hence Rain mix can be used on all orchids at every watering with no flush needed.
