Growing Basics

Light Cycle

Photoperiod strains need 18/6 for veg, 12/12 for flower. Autoflowers do 18/6 or 20/4 throughout.

Nutrients

More nitrogen in veg, more phosphorus and potassium in flower. Start at half strength.

pH Level

Soil: 6.0-7.0. Hydro: 5.5-6.5. Test and adjust regularly for optimal nutrient uptake.

Harvest Window

Check trichomes with a loupe. Cloudy = peak THC. Amber = more sedative. Clear = too early.
