Grow Mediums Hydro question ...

[steelrat]

Any experienced hydro-growers care to comment on this observation and conclusion ?

My EC has been going up by 0.3 (1.2 to 1.5) over a couple of days.

I then realised i hadn't cleaned the res on the previous week so it just had top-ups for about ten days.

I think the rapid rise in EC must be due to salt build-up ?

Did a thorough clean today and will observe.


Cheers,

steely.

Yeah that is probably what caused the rapid rise in EC, it's the only thing I can think that would make the EC rise without adding something to it.
