Ever bought a Monstera, set it by the window, and a month later the new leaves are still small with no splits? This article answers what October bright indirect light means for Hoya and Monstera deliciosa. In short, bright indirect light is strong ambient brightness where direct sun touches the leaves for no more than 1-2 hours in the morning, and a hand shadow on the leaf has a soft, blurry edge.

What Is October Bright Indirect Light?

October is the tail end of the rainy season heading into the cool season. Skies are often overcast and afternoon sun is milder than summer, but the sun sits lower, so low-angle light reaches deeper into east and south facing windows. A spot that was shaded in June may get direct sun in October. Recheck your plant spots every month.

In plant language, bright indirect light means a bright space, not a dim room where you can barely read, and not harsh sun that burns leaves. Hoya and Monstera grow under tall trees in nature, so they like filtered light.

4 Easy Ways to Measure Natural Light at Home

1. The Hand Shadow Test (free and instant)

Hold your hand about 30 cm above the leaf between 10 am and 2 pm and look at the shadow.

Sharp, crisp shadow = direct sun, too strong for Monstera leaves
Soft, faint shadow with blurry edges = bright indirect light, just right
Barely any shadow = low light, leaves get big but rarely split

2. Use a Lux Meter App

Phone lux apps give rough readings. Accuracy depends on your phone sensor, so use them mainly to compare spots in your own home. As a general reference, Monstera grows well at roughly 10,000-20,000 lux and common Hoya at roughly 10,000-30,000 lux. These are broad ranges growers use, not fixed values.

3. Check the Distance from the Window

Light drops quickly as you move away from the window. Even 1-2 meters away can mean several times less light. Keep Monstera within about 1 meter of an east-facing window. For south or west windows, pull back and use a sheer curtain.

4. Read the Plant Itself

Plants always tell us. Use this table to check symptoms.

Symptom	Too much light	Too little light
Leaves	Brown crispy burn marks, pale yellowish color	Dark green but small, no splits, stretched stems
Growth	Curling or drooping in the afternoon	Long gaps between nodes, leaning toward the window
Hoya	Pale yellow or unusually deep red leaves	No blooms, thin long vines

Adjusting Light for Faster Hoya and Monstera Growth Into Winter

Monstera: Splits Need Enough Light

Let me be direct. Leaf splits do not come from fertilizer alone. They come from adequate light, a healthy plant, and leaf maturity. Young plants not splitting yet is normal. As the plant grows and gets good light, new leaves develop more splits and holes. Give it a wooden or coir pole to climb.

Hoya: Likes Bright, Not Scorched

Hoya (Hoya spp.) is a semi-succulent climber that stores water in its leaves. It likes enough light to push new growth and bloom, such as Hoya carnosa. In low light the vines grow but rarely flower. Gentle morning sun is fine, but avoid harsh west-facing afternoon sun.

Care Summary for October to Early Winter

Topic	Monstera	Hoya
Light	Bright indirect, gentle morning sun up to 1-2 hours	Bright indirect to gentle morning sun
Watering	When soil is dry 3-5 cm deep, about every 5-7 days	When soil is fully dry, about every 7-10 days
Soil	Airy mix with pine bark and perlite	Very airy mix with pine bark, volcanic rock, coco coir
Fertilizer	Diluted balanced fertilizer once a month	Diluted once a month, reduce in cold spells

Watering frequency is only a starting point. Air-conditioned rooms, humid rooms, and black plastic versus terracotta pots dry at different speeds. Always poke the soil with a finger first. If it is still cool and damp, do not water yet.

Light Myths to Drop

Myth: indoor foliage plants do not need light. Truth: all plants photosynthesize, no light means no growth.
Myth: room lights are enough. Truth: ordinary room lights are far weaker than natural light. If you have no real window, use a grow light.
Myth: move the plant into harsh sun immediately to speed growth. Truth: leaves will burn, acclimate over 3-5 days.

Pet Safety Note

Monstera contains calcium oxalate crystals in leaves and stems. If dogs or cats chew it, it may irritate the mouth and throat. Hoya is generally considered low in toxicity but should not be eaten. Place them on a high shelf out of reach.

If your condo has just one east-facing window, good days are waiting for your Hoya and Monstera. Come adopt one and bring some healing home. We select healthy plants and pack them carefully, ready to grow with you 🪴

คำถามที่พบบ่อย

How can I measure bright indirect light?

The easiest way is the hand shadow test. If the shadow on the leaf is faint with blurry edges, it is bright indirect light. You can also use a phone lux app for rough readings to compare spots at home, but do not rely on exact numbers because each phone reads differently.

How far from the window should Monstera sit?

Within about 1 meter of a bright window. Light intensity drops fast with distance. For harsh south or west windows, use a sheer curtain or step back a little, then let the leaves tell you whether it is right.

Does Hoya need direct sun?

No, direct sun is not required. Most Hoya grow well in bright indirect light. Gentle morning sun can help flowering, but strong afternoon sun burns or yellows leaves. If the color starts changing, move it out of direct sun right away.

Why does my Monstera not split even with good care?

The main causes are insufficient light or a plant that is still too young. Splits appear when the plant is reasonably mature and gets enough bright light. Move closer to the window, give it a pole to climb, and allow some time. New leaves will change on their own.
