Plants like consistent temperatures
Make sure your plants are kept at the most productive temperature and humidity levels. The ideal growing temperatures are 21oC - 24oC (lights off) and 24oC - 27oC (lights on). The ideal humidity tends to vary according to the stage of development your plants are at - 70%-80% relative humidity is perfect for cuttings and seedlings, 50%-80% for vegetative growth and 35%-50% for flowering/fruiting plants. These settings allow your plants to function at their optimum level, so make sure your conditions are spot on with these handy measurement devices.
For digital temperature and humidity measuring equipment, please see related items (right).
