How Often Should You Water Indoor Plants with Grow Lights?

If you're growing indoor plants under artificial lighting, chances are you’ve asked: How often should I water them? It's a simple question—but the answer depends on more than just a calendar. With grow lights like those on the amoyls VerdantGlow S-Shaped 8-Tier Plant Shelf, the watering schedule is more about observation than routine.

1. Grow Lights Change the Game

Grow lights simulate sunlight, encouraging healthy photosynthesis. But more light = more growth = more water demand. If your plants sit under the VerdantGlow’s integrated grow lights for 12–16 hours a day, their soil will dry out faster than plants in a dimly lit room.

💡 Tip: Use your finger or a moisture meter. If the top 1–2 inches of soil are dry, it's time to water.

2. It Depends on the Plant Type

Succulents and cacti? Once every 10–14 days. Ferns and calatheas? Every 3–5 days. Herbs like basil? Likely 2–3 times per week. The VerdantGlow stand makes it easy to group plants by watering needs with its multi-tier design and ample vertical spacing.

🌿 Organize smart: Top shelves for low-water plants; middle and bottom for thirstier greens.

3. Container and Soil Matter

Drainage holes and the right potting mix make all the difference. Overwatering is the #1 killer of indoor plants. With the VerdantGlow shelf’s sturdy build and open-frame design, pots drain well, and air circulates naturally—helping soil dry evenly.

🪴 Pro tip: Use well-draining soil and avoid decorative pots with no drainage unless you double-pot.

4. Lighting Schedule Affects Watering

Using your VerdantGlow grow lights 16 hours a day? You'll need to check soil more often than if you're running them for 10 hours. Light drives evaporation and growth—so adjust watering when you change your lighting hours or seasons.

5. Humidity and Airflow Count Too

Indoor air, especially with heaters or AC running, can dry soil faster. The open S-shaped layout of the VerdantGlow allows for good airflow, but you may want a humidifier nearby for tropical plants.

Final Thoughts: Don’t Rely on a Schedule—Watch Your Plants

There’s no one-size-fits-all answer. Your best tools? Your eyes, your fingers, and a little patience. With the amoyls VerdantGlow Plant Shelf, you’ve already got a great foundation for healthy indoor gardening. Just remember: grow lights boost growth—but that means your plants are thirstier, too.
