Description

Replaceable cores for the Plant Watering Indicator that measures the moisture level in the soil of your potted plants. 

One pack includes two cores.

Compatible only with size M Plant Watering Indicator.

The core of the indicator will deteriorate over time. The deterioration rate may vary depending on the soil s bacterial content.

• Organic culture soil – 6 to 9 months
• Inorganic soil – 6 to 12 months
• Hydroculture – 1 to 2 years
• Bog moss or bark – 1 to 2 years
• Peat moss – 1 year

• We recommend keeping an eye on the core and replacing it as indicated above to avoid the situation where the core is already depleted and the indicator doesn’t show an accurate moisture level. 

  It’s ok to take the indicator out of the soil occasionally and check the condition of the core.
