If your seeds germinated but plant growth is stalled or the plants look unhealthy, it's not because they are "defective;" either they are not getting something they need, or they are getting something they don't need. Here's what to check:
CFLs (compact fluorescent lights) should be replaced after six months of use. While they may still appear to be bright, they lose a significant amount of their full- spectrum light over time. A plant's growth depends on getting sufficient energy from two parts of the light spectrum - red and blue - that are invisible to us. Without that energy, they can't flourish.
LEDs (light emitting diodes) are the red, white and blue 'pinpoint' lights in the hood, and will last 3 - 5 years.
If you have checked all of the points above (Water, Lights, Aeration, Nutrients) but the growth of your plants is stunted, or if their leaves are yellowing or browning, there could be other reasons:
1) Your nutrient solution has become too strong. This can occur if there are lots of dissolved minerals in your source water, or if your Seed Kit has been growing a long time without a rinse-and-refill. Nutrient imbalance usually manifests as yellowing of the leaves or browning of leaf edges, and if not corrected can lead to plant death. You can correct this imbalance by doing a Rinse-and-Refill.
2) Your plants have attracted an insect infestation. If you suspect that you may have insects on your plants, click here for more extensive troubleshooting information.
3) The water temperature is elevated to 80 degrees or above. If your AeroGarden is located in a sunny window, the water can heat up and oxygen levels in the water bowl can be severely depleted. Move the AeroGarden to a cooler, shadier location.
3) Your plants have a plant or root disease. Plants grown in the AeroGarden are not immune to the airborne and soil-borne plant diseases that afflict outdoor plants, but because they lead a sheltered life indoors, diseases are much less of a problem. The field of plant pathology is extensive, and short of microscopic examination of plant tissue by an expert it is impossible to diagnose exactly what plant disease may be affecting your plant. However, here are some plant diseases that can affect indoor plants:
