You can go the sterile route and add Hydrogen Peroxide (H2O2) to the nutrient solution or you can add beneficial bacteria which will out-compete the bad bacteria. The best way to monitor the health of your reservoir is to take regular readings of EC and pH. There are two ways to handle this. Reusing that water will provide insufficient calcium and magnesium and excessive potassium. Bacteria needs light to grow, so if you keep the reservoir in the dark it won’t have much of a chance.

Hi, it depends on the soil that you have but the best option is to wait until the meter reading goes down to the range of (1-3) where usually the “2” reding is the best choice. If you run a larger reservoir or use organic nutrients then you should use a stirring pump to mix and oxygenate the solution. It is easily adjustable and plenty powerful for a reservoir up to 30 gallons. Because of the benefits of run-off, we recommend top-feed irrigation systems for fertigating cannabis in soil, coco, or other hydroponic media. If you use this “fountain style” aeration, then the pump should be run for a couple minutes every hour and prior to each fertigation event. Always measure both the EC and the pH in the reservoir before adding top-off water. 100% ECOFRIENDLY AND REUSEABLE. I suggest to start using nutes at the second or third week and start of slowly by giving 1/8 or 1/4 of the required dose. I use the hydrofarm air pump and it is perfect for most reservoirs.

After this long list you can see that there is just too many of these factors and you can’t introduce one formula for every grower but a general watering guide can be established! As I describe in our cornerstone article “Growing Cannabis in Coco with High Frequency Fertigation”, run-off removes excess salts and helps to prevent nutrient burn. With the drip emitter system, you control flow by twisting the heads of the emitters. After your water has sat for several days in that open top container and is ready to use you also need to check it’s PH level! You can accomplish this in coco or soil by pre-watering (fertigating) the new media with the same nutrient solution that is used for the plants.
