I only change my reservoirs is there's a problem, or when I switch to plain water to flush. If a pump or tubing gets clogged, I'll prepare a fresh bucket and transfer the plant if it's not something I can easily and quickly fix. Sometimes a plant's roots break a lot and clog stuff, it stops squinting water on the roots, etc. Other than that, I let it run super low, then top it off. If there aren't problems and it's not dirty, clogged, full of algie, then let it run is how I work with it...Question for all of you.... its not WHEN.... but WHY do i need to change the water outta my system? cant seem to find a clear answer online when i search for it. all the results are WHEN to change not WHY.... im trying to understand each step needed throughout the grow. As for common sense things such as alge buildup,bacteria, and of course nutrients going bad are some things i know. but is there something i am missing?
