Lights, Plants, Action: Indoor Grow Lights Guide
Not all homes are blessed with bright, all-day sunlight — and that's perfectly okay. From south-facing rentals to cosy winter corners, grow lights make it possible for your indoor plants to thrive no matter the season or floor plan. Think of them as a natural sunlight understudy: ready to step in whenever your plants need a little extra glow.
If you're new to the world of grow lights, or you've been wondering whether your plants could use a boost, this guide walks you through everything you need to know — from how they work to which type suits your space.
Why Grow Lights Matter
Indoor plants rely on light as their primary energy source. When natural light isn't enough, growth slows, leaves pale, and overall plant health takes a hit. Grow lights fill this gap by providing the wavelengths plants need to photosynthesise — especially during winter or in low-light rooms.
Grow lights help:
- ✔ Prevent leggy, stretched-out growth
- ✔ Encourage new leaves and steady growth
- ✔ Support plant recovery after repotting or stress
- ✔ Maintain compact, healthy shapes
What Type of Light Do Plants Actually Need?
Plants respond best to wavelengths in the blue and red regions of the spectrum. These support balanced growth, strong stems, and lush foliage — the kind of healthy development you won't get from standard household bulbs.
Good grow lights mimic full-spectrum daylight. Even better, grow lights do it efficiently, with low heat and minimal energy use.
Two excellent full-spectrum options include:
- We The Wild Instant Sun Grow Bulb – a simple swap-in bulb that fits most lamps and radiates plant-friendly, full-spectrum light.
- We The Wild Instant Sun Grow Lamp – a stylish, minimalist lamp explicitly designed for plant growth, perfect for shelves or desks.
How Long Should You Leave Grow Lights On?
Most indoor plants thrive with 8–12 hours of light per day. But don't leave them on around the clock — plants need a dark period to rest.
Light recommendations:
- 🌿 Low-light plants (ZZ, Pothos): 6–8 hours
- 🌱 Medium-light plants (Philodendrons, Syngoniums): 8–10 hours
- 🌞 High-light plants (Calathea, Alocasia, Ficus, succulents): 10–12 hours
Pro tip: Add a timer so your grow light switches on and off automatically. Your plants will appreciate the consistency.
How Far Should Grow Lights Be From Your Plants?
Distance matters! Too close and leaves may scorch; too far and the light won't be strong enough.
- 💡 Grow bulbs: 20–40 cm away from foliage
- 💡 Grow lamps or panels: 30–60 cm away
Aim for a soft, even glow — not a harsh spotlight.
Where to Use Grow Lights
You don't need a greenhouse or elaborate setup. Grow lights work beautifully in:
- ✨ Dark corners where plants refuse to thrive
- ✨ Bookshelves, sideboards, or plant stands
- ✨ Offices with minimal natural light
- ✨ Bedrooms with shaded windows
- ✨ Winter months when daylight fades fast
The We The Wild Instant Sun Grow Lamp is especially handy for styling low-light plant zones without losing aesthetics.
What Plants Benefit Most From Grow Lights?
Almost every indoor plant appreciates a little supplemental light, but these groups benefit the most:
- 🌞 Light-sensitive varieties – Calathea, Alocasia, Ficus
- 🌿 Trailing plants – Pothos, Philodendron, Hoya
- 🌵 Succulents & cacti – prevent stretching and fading
- 🌱 Propagation cuttings – faster root development
- 💚 Plants recovering from stress – repotting, pests, relocation
And yes — even "low-light tolerant" plants do better with some artificial light during winter.
