"Be not simply good - be good for something." ~ Henry David Thoreau How Long Can I Store Nutrient Water? Link to full article: https://www.growweedeasy.com/how-long-can-i-store-nutrient-water by Nebula Haze If you’re growing cannabis plants with nutrients, you may wonder, “How long does a nutrient solution last before it goes bad?” Will old nutrient water hurt your
plants? Making nutrient water can be time-consuming so you might want to make extra to use in the future. How long can a nutrient solution be stored before it needs to be tossed? A few factors determine how long your nutrient water lasts before you should make more. - Lasts a long time in a closed container with minimal air – Nutrient water is best stored in a container that’s filled to the top (as little air as possible), with the cap on tight.
- Countdown starts when nutrient water is stored with air – Once you’ve used up some of the water, there will be air
in the container even if you close it tightly. This closed environment with air and nutrient water creates a perfect home for microorganisms that make your water go bad.
- Mineral-based nutrients last longer – Organic nutrients tend to go bad faster than mineral-based nutrients, but all nutrient water will go bad once the wrong environment is formed (microorganisms like nutrient water too!)
As long as your container is filled to the top and closed tight, nutrient
water acts a lot like milk. It stays fresh a long time before you open the container. But just like milk, once it’s opened, you’ve started a countdown until it goes bad. Also like milk, if nutrient water smells bad or looks different, it’s bad regardless of the “best by” date or how long it’s been stored. So your nose and eyes are the final judges. If nutrient water looks weird or doesn’t pass the smell test, it’s time to make more. Plants react poorly to bad nutrient water How to maximize nutrient solution storage
Mixing nutrient water is time-consuming, but making 1 gallon takes a similar amount of work as 5 gallons. That means you can save time by making a lot of nutrient water, then watering plants as needed. This section will teach you how to make your nutrient water last as long as possible so you don’t have to
make it as often.
1.) Cap on or off?
It may not seem like this would matter much, but the cap of the nutrient container actually makes a difference when storing nutrient solution. Here’s what to do to maximize storage. - Screw the lid on tightly when the container is full (or close to full) to keep air out. A full container of nutrient water with the lid on tight and kept in a cool dark place lasts for a long time.
I’ve kept nutrient solution like this for weeks.
- Keep the cap unscrewed when nutrient solution is low because making it airtight at this point would trap too much air in the container. At this point, the nutrient solution will last longer if it gets access to fresh air. If nutrient water is trapped in a container with a lot of air, it creates anaerobic conditions that encourage microorganisms to grow. You’ll immediately be able to smell their yucky musk when you open the
cap.
A completely full container of nutrient water with the cap on tight (and stored according to the instructions below) will last a long time. Once the nutrient solution is low, the cap traps too much air inside and should be kept unscrewed to keep nutrient water from getting smelly Mineral Nutrients Are Our Favorite!Don't get me wrong, I love organic growing and organic nutrients. But mineral nutrients (like General Hydroponics Flora Trio) has been the bread and butter of our grow room for over a decade. If you've ever needed a tested formula that's known to work, this is it! FoxFarm, the markers of our favorite organic nutrients, joined the party with Cultivation Nation! They also have a line of 100% mineral nutrients that work well and last a long time in pre-made nutrient water. If you're looking to make nutrients in advance, you can't go wrong with either of these two nutrient lines. Plus, they've both been tested by use with real cannabis grows, so you know they work! Autoflowering Grow Day 73: 1 Week to Harvest! Here are the plants at 73 days old from germination. Here's a closeup of a Zkittlez Auto bud. The hairs have mostly turned dark, but they haven't all fully curled in yet. I believe the buds need one last week yet for max potency and bud size. Get ready for tons of harvest pictures next week! ~Nebula We'd love for you to join us with your own photoperiod grow! Think of it as a grow challenge we can all go through together. If you're a little ahead (already sprouted) or behind (can't germinate yet this week), that's okay! We can still be together in spirit :) HIT REPLY if you're joining us, and let us know your setup and strains. We'd love to hear what you're up to, and
we may feature you in a future newsletter! ~Nebula
