How long should LED grow lights stay on each day? – Soltech Solutions

The daily runtime of your grow light depends on the type of plant and how much natural light it’s getting. As a general rule for the Aspect™ Gen 2:

Low to Medium-Light Plants:

Run the light for 10–12 hours per day. These plants don’t need intense light but still benefit from a steady, daily boost.

Medium to High-Light Plants:

Keep the Aspect™ Gen 2 on for 12–14 hours per day. This ensures they get enough energy for active growth, especially in darker rooms or during winter months.

Flowering Plants:

Follow a 12 hours on / 12 hours off cycle to mimic natural light patterns. This encourages blooming and supports photoperiod-sensitive species.

Use the included timer to automate your light cycle and avoid overexposure or missed days. For most homes, we recommend syncing the light to your waking hours, creating a routine that aligns with your environment and your plant’s rhythm.
