yes you can, however i still flush for two reasons
1) its free
2) somthing about using more chemicals to get rid of the old chemicals seems odd.

I've used Final Phase with the last few times I've flushed and have actually noticed a difference in the quality of my final product. Whether it's actually worth the extra time and effort I suppose would depend on how heavy you go on the nutrients during your grow. I've used it only with my soil grows and can confirm that it helps give a higher quality, cleaner burning smoke...but that's just from my own experience. If you grow 100% organic then this is likely a waste of time.

i grow in soil. how do you use final phase and when ??
