Are you tired of testing your pH?
There's an easier way!
The Importance of pH
Once you've added water and Tower Tonic, it's time to test the pH!
If the pH is too high, or too low, your plants cannot take up essential nutrients. Even though you're adding minerals to the water, if the pH is off, the plants cannot use them. Getting the pH 'just right' is important!
Did you know? The pH of your household water is influenced by the bedrock under your feet. Most of Florida is built on limestone, which is alkaline. If you test the water coming out of your tap, it most likely has a high pH (7.8-8.4). You need to lower the pH to 5.5 in order for your plants to grow healthy. To do this, you need to add "pH Down".
Note: some people are lucky and do not need to adjust their pH. If your pH is 5.5-6.2, you don't need to adjust!
Here are some simple steps to take to adjust your pH:

1. Fill up your Tower Garden basin with water. Use non-softened, chlorine, and chloramine-free water.
If you have the FLEX, add 200ml of Tower Tonic A and 200ml of Tower Tonic B. If you have the HOME, use 130ml of Tower Tonic A and 130 ml of Tower Tonic B.
3. Plug your pump in to circulate the water. Wait a few hours for the pH to adjust.
4. Test your pH. Add a small amount of pH down or pH up if needed. I use the cap to 'measure' but you can also use a tsp or tablespoon.
5. Test again. If needed, repeat #4 until your pH is 5.5.
6. Note how much pH down or pH up you need to add to reach a pH of 5.5.
The number you use (for example, 2 capfuls) is the number you need to add every time you fill up your Tower Garden.
If your Tower Garden is half empty, then you'll add half as much water. Add half as much pH down or up.

Never test again? Going forward, ONLY test your pH if you observe a problem in the color of your plant leaves. The leaves should be the same color as the veins.
As long as the veins in the leaves and the leaf is the same color, you're doing fine. If your veins and leaf is the same color, you don't even need to test your pH. JUST ASSUME IT'S GOOD.
The Tower Garden FLEX holds 20 gallons of water. The Tower Garden HOME holds 13 gallons of water.
