Cultivation and Growth Guidance

To ensure optimal development and mitigate common growth challenges such as weak stems or poor germination, please follow these horticultural practices:

• Germination Environment: Maintain a consistent soil temperature between 70°F and 80°F (21°C–27°C). Use a sterile, well-draining seed starting mix to prevent fungal issues that can cause leaf spotting.
• Light Requirements: Provide 12–16 hours of direct light daily. If seedlings appear stringy or elongated, increase light intensity or move the light source closer to prevent etiolation.
• Watering Practices: Allow the top inch of soil to dry out between waterings. Avoid overhead watering to keep foliage dry, which helps prevent the development of dark spots or fungal pathogens on leaves.
• Nutrient Management: Once true leaves appear, apply a balanced, water-soluble fertilizer at half-strength to support steady, robust stem development.
