Alocasia Silver Nebulas are pretty flexible with lighting conditions. They can survive in low light but truly thrive in bright, indirect light.

If you’re aiming for rapid growth and those signature large leaves, place it in a well-lit area but out of direct sunlight. Direct sun can scorch the leaves, and no one wants that.


When it comes to watering, timing is everything. Wait until the top two inches of soil feel dry to the touch, then give it a good soak. These plants like their soil to stay consistently moist but not waterlogged.

If you notice the leaves starting to droop, that’s your cue to water immediately. Don’t procrastinate on this!

Tip: This is also why semi-hydro is best for Alocasias.


Alocasias are fans of nutrient-rich, well-draining soil.

Opt for a mix that includes organic matter like coco-coir, peat moss, or shredded leaves. Avoid soils that have moisture-retaining crystals.

If you find the soil draining too quickly, it’s time to re-pot in a compost-rich mixture with fewer drainage materials.

Tip: Consider using LECA/Pon for Alocasia for the best experience.


Originating from subtropical regions, Alocasia Silver Nebulas prefer a warm environment. Keep the room temperature above 60°F, and they’ll be content.

If you’re thinking of giving them some outdoor time in the summer, make sure to bring them back inside before temperatures dip below 50°F.

Sudden temperature changes are a no-go.


These plants love humidity—think above 50%. If you’re in a dry climate or your indoor air lacks moisture, consider using a humidifier or setting up a pebble tray filled with water. This will help maintain the humidity levels that these plants crave.


When your Alocasia is in its growing phase, regular feeding can make a world of difference. You can use a diluted liquid fertilizer, a fish/seaweed emulsion, or even slow-release granules. If the plant is dormant, skip the fertilizer; it won’t need it.

Growth Rate

Once the Alocasia Silver Nebula is comfortable in its new home, you’ll notice quick growth, especially during the warm months. However, don’t expect it to turn into a towering giant; indoors, it usually maxes out at around 3 feet.

Pet Safety

Attention pet owners: This plant is toxic to animals. Make sure to place it somewhere your furry friends can’t reach.

Grow in Semi-Hydro

  • Alocasia plants excel in Semi-hydroponics (LECA/Pon) due to their natural inclination for root growth and humidity.
  • Successfully transitioning Alocasia to Semi-hydroponics is enhanced with a Nutrient Stagnant Wicking (NSW) setup.
  • Alocasia roots adapt seamlessly to the water in LECA/Pon, with quick resolution of any root hair issues in NSW setups.
  • Fertilization protocol includes a nutrient mix concentration of approximately 800-1000ppm.
  • These plants are versatile in different temperature and humidity settings, thriving in controlled environments.
  • Long-term care involves maintaining a constant water reservoir and performing occasional system flushes for sustained growth.


  • Rotate the pot a quarter-turn every time you water to ensure even light distribution.
  • These plants like to be a bit root-bound, so don’t rush to re-pot them.
  • Alocasias have rhizome-type roots that store extra water. To propagate, simply cut a section of the root and plant it.
  • Keep an eye out for pests like mealybugs. Organic solutions like neem oil are your best bet for prevention.

And there you have it—your comprehensive guide to caring for the Alocasia Silver Nebula. With the right care, this plant will be a showstopper in your collection.

Happy planting! 🌱
