Depending on the complexity of the setup I would either:

Build a very small and basic system that you can use for flush consisting of a small res and a basic pump. Focus must still be kept on circulation and oxygenation, and at the least use distilled. You can build a system like this for very cheap, you would be surprised.

Put them in bins, and manually administer distilled or RO water, depending on setup this could be laborious.

Flushing makes a noticable difference in the taste, texture, smoothness, toxicity, combustion, and body of the dried medicine.

AquaponicHerb Reviewed by AquaponicHerb on . Flushing a perpetual hydro garden? I am using a ebb and flow system with 9 plants (moving 3 in every month or so). My question is that I am getting ready to harvest my first 3 and I was wondering how I go about flushing. Do I just final flush the whole system, harvest the 3 that are ready, and just go back to my nute schedule when I'm done adding the new 3? Will that mess up the other 6 that are in there? I was also thinking about going the aroponic way and I have the same question with that system too. Anyone have Rating: 5
