Plant spinach seeds in a shallow container with rich potting soil, ensuring good drainage. Keep the soil consistently moist and provide at least 12-14 hours of light daily using grow lights to encourage rapid growth.

Transplant artichoke plant starts into larger pots with well-draining soil and ample space for root development. Artichokes require plenty of sunlight, so position them under grow lights for 10-12 hours a day and maintain consistent moisture.

Harvest spinach leaves when they are young and tender, usually within 3-4 weeks from planting, by snipping the outer leaves. Artichokes can be harvested when the buds are tight and firm, typically within 2-3 months after planting, by cutting the stem a few inches below the bud.
