Life Period
Timing depends on variety, production system and environment, desired size of
plants, and planting density.
Recommendations for Indoor & Greenhouse Environments
Lighting
- Management of light intensity throughout all growth phases is critical and has lasting effects on plant maturation and yield.
- We recommend 23-30 DLI (i.e., 350-450 PPFD in an 18:6 vegetative cycle) at sowing with an optimal increase to 28-43 DLI (i.e., 650-1,000 PPFD during the 12:12 flowering cycle), depending on inputs (e.g., CO2) and plant health.
- The flowering cycle requires a 12:12 dark period.
- Any interruption with light exposure during the dark period may result in a hermaphroditism event.
- Supplemental lighting is helpful during shorter day lengths or in low-light regions.

Additional Recommendations
Growth Media
Phylos seeds germinate best in a well-draining, soilless media that allows
for good seed-to-soil contact.
Sow/ Transplant
- Sow seeds in 50-72 cell plug trays directly into growth media at an ideal depth of¼ inch but no deeper than½ inch.
- Seedlings need high light intensity immediately after germination to prevent plant stretch: 350 – 450 PPFD after seed sow.
- Transplant within 14-21 days after emergence dependent on the plant size and root development.
- Avoid saturated conditions, but keep the growth media evenly moist. We advise against using rock wool due to the difficulties of maintaining proper seed-media contact. We do not recommend using propagation domes as it keeps humidity levels too high for seedling health.
Soil Salts and pH
- Media pH should range between 5.8-6.2, and EC 0.5-3.0. See Table 1 for recommended EC.
- Frequent media and pour-through tests will help determine appropriate EC and help with fertilizer calculations. It is good practice to calculate the base EC of the water source to add into the equation.
- A reputable fertilizer provider will have personalized feeding recommendations based on your specific grow conditions. Follow a balanced feed plan like FloraPro Grow, FloraPro Bloom, and FloraPro Cal+Micros per their recommendations.
Lighting Regime
- Unlike clonal production, seeds require higher light intensity immediately at emergence.
- Apply an 18:6 light cycle during the vegetative period for optimal results.
Vegetation
- Pot size and density used for clonal propagation can be applied to seed production.
- Seedlings and clones can be grown using the same production schedule.
- Follow de-leafing schedules to ensure proper airflow for proper under-canopy maintenance.
