Storing water with nutrients left in?

Hello I have a question trying to get a response. Is it ok to let my water sit with nutrients in it?been 6 days. I made 5 gal only used 3. Also I use a gallon per plant roughly if I’m mixing a five gal jug does that mean each plant is getting what it need from the gallon of water? Sorry new to the grow world…

Try not to mix more than you will use in 2-3 days. If you adjusted pH it will need it again after 4-5 days. If you do have it mixed for days you need to keep it moving, pump, wave maker, air pump. Wouldn’t use it if it’s been stagnant.


I find when i use Mantis Buffered Nutrients I can mix up a gallon and use it over several days. As long as i put it in the fridge so it doesn’t sit any longer than 2 days. But also before i use it again i shake it really well to mix it all up again. But if you refrigerate it let it sit out for a bit so its not ice cold on your roots.

Thanks fellas I am just going to use a gallon at a time. Each plant takes about a gallon.


I mix 30 gallons of nutrients a week and keep in a 35 gallon reservoir.
I have 2 wave makers in there to help mix the nutrients in there 24 hours a day.
I do check the ph daily as it does go up after a day or two.
Good luck and happy growing.

Thank you
