TerraLED advice

A yellow leaf may be part of normal ageing or point to several growing problems. Start with observation and the roots; do not automatically apply fertiliser.

Start with the location and the area of foliage to light. The lamp shape, mounting and settings matter as much as electrical power.

A grow light provides light for plants. Choosing one means distinguishing power consumption, spectrum and the light that actually reaches the growing area.

A 600 W rating alone cannot determine the distance from the foliage. High-power setups require consideration of the model, coverage and heat constraints.
