• Direct filling — use the potting soil as is, without adding fertilizer during the first 2-3 weeks of cultivation.
• Moderate watering — the 700ml/L water retention requires spaced watering, check deep moisture before watering.

• Gradual transition — after 2-3 weeks, gradually introduce your favorite fertilizers to maintain growth.

You will achieve steady and vigorous growth, with a developed root system and resilient plants.

Joseph's Tip: "I recommend never adding fertilizer during the first two weeks — this potting soil is rich enough and you risk burning your young roots. Patience is rewarded!"
