Houseplant FAQs
Clear starting points with room for real homes, seasons and climates.
Humidity
Should I mist my houseplants?
Misting raises humidity only briefly and is not a reliable fix for dry air. Grouping plants, moving them from vents, or using a clean humidifier is usually more effective. Avoid leaving susceptible leaves wet for long periods.

Light
What does bright indirect light mean?
It is strong ambient light without prolonged harsh sun striking the leaves. A position near a bright window with a sheer curtain or just outside the direct beam is often suitable, but window direction and climate change the intensity.

Can a plant survive in a room without windows?
Most plants cannot remain healthy indefinitely without usable light. A suitable grow light on a timer can make a windowless room workable; ordinary room lighting is usually inadequate.

Pet safety
Are pet-safe plants completely harmless?
Pet-safe classifications generally mean a plant is not known to be toxic, not that eating it is beneficial. Chewing any plant can cause irritation or stomach upset, and treatments on leaves may add risk.

Plant Lab
Does Plant Lab predict exact plant survival?
No. It is an accelerated educational approximation. Use it to explore interacting conditions, then observe your real plant and its roots.

Plant diseases
How do I know whether a plant has root rot?
Several clues together are more useful than one yellow leaf: mix that stays wet, an unhealthy smell, continued wilting, and roots that are dark and mushy rather than firm. Inspect roots only when the evidence justifies disturbing the plant.

Pottery Studio
Are downloaded pots guaranteed watertight?
No. Layered prints can leak, and results vary by material and printer. Inspect the STL in your slicer, test a print and use a saucer or nursery-pot liner.

Soil and pots
Do indoor plants need drainage holes?
Drainage holes make watering mistakes easier to avoid because excess water can escape. Cachepots without holes are best used as decorative covers around a draining nursery pot.

Watering
Should I water houseplants on a fixed schedule?
Use a schedule as a prompt to check, not an instruction to pour water. Test the mix, observe the plant, and account for light, season, pot size and temperature before deciding.
