General guide values for herbs, vegetables and houseplants. Always check the needs of your own plant and the nutrient maker's instructions.
| What | Guide value |
|---|---|
| Most houseplants, day | 18–24 °C (65–75 °F) (MU, Cornell) |
| Most houseplants, night | 16–18 °C (60–65 °F) (Cornell) |
| Lettuce indoors | at most 24 °C by day, 18 °C at night (UK CCD) |
| Humidity | 40–60 % RH (MU) |
Practical tips
- Keep plants away from drafts, radiators and heaters (Cornell).
- Humidify dry winter air with a humidifier or a pebble tray under the pot – pot bottom above the water (Cornell, MU).
- Lights produce heat: take care of ventilation and air circulation; a fan at canopy level helps (VCE).
- In winter plants grow slower and need less water and fertiliser (Cornell).
