Houseplant quick-lookup tool

Indoor Plant Growth Reference

Filter 20 common houseplants by natural growth pace, DLI, humidity and temperature. Calculate your light total or VPD, then compare up to four plants side by side.

Quick reference

Use these as starting bands, then watch the plant and adjust for season, substrate, pot material and local conditions.

Tropical room target18–27°C · 50–70% RH · roughly 0.8–1.2 kPa VPD
DLI ladderLow 3–8 · medium 8–15 · bright 15–25 · high 25–40+ mol/m²/day
Root-bound responseRepot only when indicated, usually into a container 5–7 cm wider.
Seasonal ruleFeed during visible active growth; reduce water and pause feeding when growth stops.

Translate room measurements into plant metrics

These calculators turn grow-light readings and room conditions into the same units used in the lookup table.

DLI calculator

Daily Light Integral = PPFD × light hours × 0.0036.

6.5 mol/m²/day Low-light band

VPD calculator

Estimates air VPD in kPa, assuming leaf temperature equals room temperature.

Side-by-side comparison

Select up to four plants from the table. The cards retain your choices while you change filters.

Growth-stall troubleshooting

Start with the measurable condition most closely connected to the visible symptom.

Long, pale or leaning growth

Check first: DLI and distance from the window or grow light. Increase usable light gradually.

Wilting while soil is wet

Check first: drainage and roots. Saturated media can deprive roots of oxygen and lead to rot.

Crisp edges in a warm room

Check first: VPD. High temperature plus low RH can create leaf-water stress.

No new growth in winter

Check first: seasonal DLI. Reduce watering and do not force growth with extra fertiliser.

Roots visible; soil dries very fast

Check first: root binding. Move up one pot size rather than overpotting.

Brown tips after feeding

Check first: fertiliser strength and salt buildup. Pause feeding and flush a draining pot.
