Programmable Sunrise & Sunset Controller for Indoor Plants. Bring the rhythm of nature into your home.

The HappyBird SunCycle Timer helps your plants thrive by simulating natural daylight — with gentle sunrise and sunset transitions that reduce shock and support healthier growth. Instead of an abrupt light switch, your grow lights will gradually brighten and dim over a 20-minute period, just like the sun.

Simply plug the timer between your grow light and its power source, set your custom on/off times, and let your lighting run automatically — every single day.

⚠️ Please Note:

The Timer is only compatible with DC (Direct Current) voltage lights.
It will not work with standard AC-powered lighting or wall plug systems.

With a maximum load of 36W, it’s the perfect fit for low-voltage LED grow lights used in indoor plant setups — from herbs and seedlings to tropical foliage.

Tired of guessing your plants' light needs?

Most indoor plants suffer from irregular light schedules — especially during winter or in low-light rooms. Manual timers and inconsistent setups stress your plants and stunt growth.

The Right Light Cycle = Healthier Plants 🌱

The HappyBird SunCycle Timer isn’t just a convenience — it’s a growth essential. By replicating the natural rhythm of daylight, it gives your plants the stable environment they need to truly thrive.

🌿 Mimics the Natural Day-Night Cycle

Instead of a harsh on/off switch, the timer gradually brightens in the morning and dims in the evening — just like the rising and setting sun. This smooth transition reduces stress on your plants and supports their internal biological clocks (photoperiodism), which directly affects growth, health, and energy storage.

🍃 Helps Prevent Leaf Drop and Weak Growth

Sudden changes in lighting can shock sensitive plants, often leading to yellowing leaves, stunted growth, or shedding. A stable light routine promotes stronger, more resilient foliage by giving your plants time to adapt gently to light changes throughout the day.

🌸 Encourages Flowering and Fruiting (When Conditions Are Right)

For light-sensitive plants, a consistent schedule is key to triggering blooming or fruiting. The SunCycle Timer supports optimal photoperiod timing, helping you stimulate growth phases naturally — especially helpful for herbs, ornamentals, or flowering species.
