I wouldn't say this is fact but from personal exprerience, i have a large unused sink that i used to mix up 15l of nutrients in and that would last me weeks, so i don't think it would do much harm. But if anyone knows or has experienced different then I'll be happy to be proved wrong.(also i always leave my water standing for days before watering them)
cornish_dope Reviewed by cornish_dope on . wasting nutes i dont like wasting nutes down the drain every time i feed my plants. or having to mix them every time. is it ok to hold my nutrient solution for a day or to and use it then? will it hold its nutritional properties, or will it go to shit and be bad for the plants. im using fox farm grow big and big bloom. and thrive alive B1 sometimes.
