It means to take filtered water if u have it. PH the water to 6.5-6.8.
Then pour it in untill it all drains out of the bottom.

Then do it again.
Not to sure how much you should do it, but basically u attempt to "flush" out all of the nutes u put in.

p.s. never heard of anyone putting the ferts right on the dirt. dosent seem like you would get a good mixture by doing this. my 2 cents.
bob bobbinson Reviewed by bob bobbinson on . How does 1 properly FLUSH His Herb plant?? I'm new to growing and just started w/ a 75w cfl. I messed up when I gave my plants sum nuts(24/8/16) I didnt add it to the water but put it on the soil then watered. Plants looked healthy before I left town. I called a few days later and my wife said the leafs seem to be yellowing and curlin' down. I found your site and sum 1 mentioned flushing. I figured what it meant, but don't exactly know how.Help anyone?? These are just sum sprouts I found outside my home. Doing good off the cfl around Rating: 5
