Grow Lights: How to Keep Your Houseplants Thriving (Even in a Rochester Winter)

If you’ve ever watched a plant slowly decline all winter—stretching, fading, dropping leaves—you’re not alone.

Short days + weak sunlight = struggling plants.

That’s where grow lights come in. And honestly? They’re one of the easiest upgrades you can make to your plant setup.

At Prop Me Up, every bulb in our shop light fixtures is a grow bulb; in fact, we also sell the exact bulbs we use.

🌿 What Are Grow Lights (Really)?

Grow lights are artificial lights designed to mimic the sun—giving plants the energy they need to photosynthesize.

The key thing:
👉 Not all light is equal.

Your living room might feel bright, but to a plant, it’s often barely enough to survive.

☀️ Why Your Plants Struggle Indoors

In places like Rochester NY:

• Winter daylight drops to ~9 hours
• Sun angle is weak
• Windows block a lot of usable light

Result?

• Leggy growth
• Slower or stalled growth
• Leaf drop
• Washed-out color

👉 A grow light fixes all of that instantly.

🪟 The Hidden Problem: Your Windows Are Working Against You

Here’s something most people don’t realize:

Modern windows are designed to block parts of sunlight.

That’s great for energy efficiency—but not great for plants.

Most newer windows (especially double-pane or Low-E glass):

• Filter out a large portion of UV light
• Reduce overall light intensity
• Reflect some of the sun’s energy away

Now—to be clear—plants don’t need UV specifically to survive.
But that filtering comes with a tradeoff:

👉 Less total usable light reaches your plant.

So even if a room looks bright to you, your plant is getting:

• Lower intensity light
• Shorter effective exposure
• Less energy for growth

Combine that with winter conditions, and it’s basically a slow starvation diet.

🔍 What Actually Matters

1. Full Spectrum (This Is Non-Negotiable)

You want full-spectrum LED lights (look like normal white light).

Avoid the old purple “blurple” lights unless you’re growing in a basement lab.

👉 Your plants AND your space will look better.

---

2. Brightness (The Part Most People Get Wrong)

• Distance matters more than raw power
• A weak light close up beats a strong light far away

Rule of thumb:
👉 6–12 inches from plant = ideal for most setups

---

3. Duration (Consistency > Intensity)

• 10–12 hours per day is the sweet spot
• Use a timer (seriously—this is a game changer)

⚠️ Common Mistakes

• Putting the light too far away
• Running it only a few hours a day
• Assuming a bright room = enough light
• Ignoring how much windows reduce usable light

🌱 Final Thought

Your plants aren’t dying because you’re bad at plants.

They’re struggling because:

• The sun is weaker
• Your windows filter the light
• And indoor conditions aren’t natural

Grow lights fix all three.

And once someone uses one?

They don’t go back.
