The hydroMazing smart garden system is designed to monitor and manage your growing environment by automatically controlling fans, heaters, lights, water pumps, and now, the nutrient solution.
The nutrient solution level of the hydroponics container system must be monitored.
As the nutrient solution level decreases it needs to be replenished with fresh water, otherwise the nutrient solution becomes more concentrated and some plants won’t respond well. The hydroMazing Nutrient Controller can activate a pump that adds fresh water to bring the concentration back to the level it was when started, often referred to as “topping-off.” The hydroMazing Nutrient Controller will also monitor your pH and EC, activating pumps to manage the solution, and notifying you when you need to make changes.
There is no need to adjust your pH or EC until it is necessary.
This is a big one! There is a lot of misinformation out there about keeping the pH and EC regulated. If I were paranoid, I’d say it was a conspiracy from hydroponics manufacturers and retailers who want to sell more consumable product. Don’t get me wrong, proper pH and EC is important, even critical, to the success of a plant.
The pH of water is an important measurement whether you are gardening indoors or outdoors, soil or soil-less, because it affects whether a plant can properly take in nutrients. Even though hydroMazing monitors your pH and EC, I still recommend a handheld pH tester such as the Oakton EcoTestr pH 2 Waterproof pH Tester, which is excellent for the home gardener and has been proven time and again to be accurate.
The electrical conductivity (EC) of water estimates the total amount of solids dissolved in water, or TDS (Total Dissolved Solids). TDS is often measured in ppm (parts per million). In hydroponics, this measurement is used to determine the approximate concentration of nutrient solution to water. There are many hand-held EC devices available as well.
When do I need to adjust the pH?
Only under the following conditions:
pH is at or below 5.0 or above 6.5
AFTER at least 30 minutes from the time of topping-off or changing the nutrient solution.
How to adjust? I highly recommend using pH Up and pH Down from General Hydroponics sparingly and only when necessary.
Flushing means to literally flush empty the nutrient solution from the hydroponics system and replace it with fresh “good” tap-water. Then return the nutrient solution back to what it should be for the phase of growth.
When in doubt, flush the system and refresh the nutrients. Otherwise, it’s recommended to flush your recirculating system every 7 – 14 days. When I grow, I try to keep the nutrient solution working as long as possible, however, salts build-up over time and it is good to flush with fresh water from time to time.
