Fast-growing hydroponic bok choy in DWC system

Bok choy is a hydroponic speed star, producing crisp, mild Asian greens in just 30-45 days. This versatile vegetable adapts perfectly to hydroponic systems, delivering restaurant-quality produce with minimal effort.

Why Bok Choy Thrives Hydroponically

Bok choy loves the consistent moisture and nutrients hydroponics provides. The controlled environment prevents the bolting that plagues outdoor-grown bok choy, ensuring tender stems and leaves every time.

Fastest Bok Choy Varieties

Baby Bok Choy (21-30 days)

Compact heads harvested young for maximum tenderness. Perfect for stir-fries and salads.

Shanghai Bok Choy (30-35 days)

Light green stems with spoon-shaped leaves. Mild flavor and quick growing.

Pak Choi (35-40 days)

Traditional variety with white stems and dark green leaves. Slightly slower but excellent texture.

Tatsoi (30-35 days)

Rosette-forming Asian green with spoon-shaped leaves. Excellent cold tolerance.

Growing Conditions

Maintain nutrient solution at 60-70°F for best results. Bok choy tolerates light frost, making it ideal for cooler growing environments or unheated greenhouses.

Nutrient Management

Use a balanced nutrient solution with EC of 1.5-2.0. Calcium is especially important for preventing tip burn on inner leaves.

Harvesting Options

Harvest baby bok choy whole at 4-6 inches tall, or wait for full-sized heads at 8-12 inches. For continuous harvest, remove outer leaves while leaving the center to regrow.
