In short: Light is a plant's most important source of energy – more important than water or fertilizer. Without enough light, a plant can't produce energy, no matter how well you water or fertilize. How bright a spot really is for a plant is hard to judge by eye, because glass, curtains and the season change the amount of light considerably.

Why light matters more to plants than water or fertilizer

Many plant lovers make a crucial mistake: they believe their plants mainly need water and fertilizer to grow. But the most important thing plants need to survive is light. Light is to plants what food is to us.

Fertilizer? That's just the dietary supplement. And without the "basic nutrition" provided by light, your plant can't produce energy – no matter how often you water or fertilize.

The problem: choosing a location by gut feeling

Many people place their plants wherever it looks nice or wherever there's still room. But:

• Not all windows are the same
• Light conditions change with the seasons
• Glass, curtains and neighboring buildings drastically reduce the amount of light

We often think a plant is in a bright spot. But from the plant's point of view, it's already too dark for healthy growth. The consequences:

• Leaf discoloration & leaf drop
• Leggy growth & instability
• Stunted growth
• Susceptibility to pests and diseases

FYTA measures what you can't see

A lack of light is hard for us humans to detect. Our eyes automatically adapt to different lighting conditions. Plants can only do so to a limited extent. That's why the FYTA Beam G2 and the FYTA Sphere show you in real time how much light actually reaches your plant's location.

And not in lux, but in a plant-relevant unit (PAR):

• Daylight quantity over 24 hours
• Intensity and duration
• Matched to plant needs

Find the best location with FYTA

FYTA analyzes the light values at your location and compares them with your plant's needs. You get clear recommendations, for example:

• “Too little light for growth”
• “Ideal for light-loving plants”
• “Location too dark in winter”

You can test different spots to find the best place – and FYTA's live mode tells you instantly whether it's a good fit.

Conclusion: good light, healthy plant

If you want your plants to thrive, you have to give them light. FYTA helps you find the perfect balance of location, watering and fertilizing.

No more guessing, no more googling – relevant plant knowledge right in the FYTA app.
