Troubleshooting Indoor Tower Garden Growing Issues 🌿💡
Growing indoors with your Tower Garden is a fantastic way to enjoy fresh, homegrown produce year-round. But sometimes, things don’t go as planned. Maybe your lettuce looks leggy, your tomatoes won’t set fruit, or you’ve spotted an unexpected guest (hello, gnats 👋). Don’t worry—these are common hiccups, and most can be solved with a little troubleshooting.
Here are the most common indoor growing issues and how to fix them:
1. Weak, Leggy Plants 🌱➡️📏
Cause: Not enough light, lights placed too far away or not enough complete darkness.
Fix:
-
Position LED grow lights equidistance from the plants. It will be about 6–8 inches from the plant canopy.
-
Keep them on 14–16 continuous hours per day to mimic natural daylight.
-
Ensure your plants have complete darkness for the rest of the 24 hour period.
2. Yellowing Leaves 🍋
Cause: Could be nutrient imbalance, pH off, or overwatering.
Fix:
-
Test pH (ideal range: 5.5–6.5).
-
Add Tower Tonic Mineral Blend according to the feeding schedule. Full details can be found here.
-
Empty and refill the reservoir every 1-2 months to prevent Nutrient Lock.
-
Ensure the pump is plugged into a timer. Set the digital timer to "I" for indoors or set an analog timer to 15 on, 45 minutes off.
3. No Fruit 🍅🍓
Cause: No pollination due to no wind or bees indoors.
Fix:
-
Hand-pollinate with a soft brush or gently tap flowers.
-
Use a small fan to circulate air and encourage pollen movement.

4. Pests Indoors 🐞🐛
Yes, even indoors you may encounter pests like aphids or fungus gnats.
Fix:
-
Inspect new seedlings before adding them to your tower and rinse in a mild neem and soap solution.
-
Check your Tower daily for pests.
-
Treat for pests at the first sign using an appropriate pesticide.

5. No Growth or Stunted Plants ⏸️
Cause: Nutrient lockout or low oxygen.
Fix:
-
Clean and refresh your reservoir.
-
Check that the pump is circulating on a timer. Continuous watering reduces the amount of oxygen the roots can absorb.
-
Avoid over-fertilizing—too much of a good thing can block nutrient uptake.
