I always thought the opposite.. especially since all books I have read say to change the resivor..

that being said..I always top off..
especially when the plants are late into veg and flowering.. they consume so much water and nutrient that I have never had a problem..

Although I hate to admit it, I like tormcookers thoughts about adding 1/2 strength.. and just build up...

I have always heard what Zandor said.. change resivoir every 7 days...

NEVER done it myself but....

i love you


either way, you should keep a close eye on your plants.. they will tell you what they need


i love you
Garden Knowm Reviewed by Garden Knowm on . Top off res with nutrients or just water? Hi, after mixing a fresh reservoir of nutes (in an aero system), the ppm was 1350. 24 hours later, it was just under 1000. Next day, it was under 800 â?? a pretty weak level for foot-plus plants. Iâ??m a complete newbie to hydro, so I was wondering: should I be replacing what they eat everyday (bringing the ppm level back to 1350 daily), or should I let the plants drain the drink down to ? I read on this forum one opinion that replacing what they eat is good. But logic is also telling me Rating: 5
