Flushing

[Hedons]

First grow... I started with whatever seeds I could get my hands on, and by the looks of things I have three different strains.

In a grow with 3 different strains that are flowing and maturing at 3 different rates, should they be flushed when the first strain is nearing harvest time? Or will that adversely affect the other two?

How many days should flushing go for on a ebb and flow system?

Thanks

I am also curious to know also how often to flush an ebb & flow system

 

[trillions of atoms]

drop all nutes 7-10 days before chop giving only ph'd water.....i do it longer in soil than compared with hydro.

considered flushing in the longrun, not just a buncha water at once......altho some ppl would beg to differ. i guess all matter of opinion here.

You can usually flush out a hydro system quicker than soil since there is usually less of a "buffer" holding nutes in. 7-10 all the way to two weeks is plenty good in hydro, 2 weeks depending on how anal you are on getting every bit of nutes out.
It's kind of a line on how long you want to keep them fed to maximize output and how much of the nutes you want to take out.
