Essential Materials for Growing Red Amaranth

High-quality supplies ensure vigorous growth and bold hues.

Trays and Growing Medium

Shallow 10x20-inch or 8x8-inch trays with drainage holes, using 1–2 inches of moist coco coir, peat, sterile potting mix, or germination pads.

Seeds

7–8g non-GMO red amaranth (Red Garnet or Burgundy) per tray from suppliers with 85%+ germination rate.

Equipment

Red-blue or full-spectrum LED grow lights (6–12 inches above), oscillating fan, spray bottle, sharp scissors, pH 6.0–7.0 water. Optional: vermiculite topcoat and diluted organic fertilizer (4-4-4 NPK).

Step-by-Step Growing Guide

Maintain 21–29°C (70–85°F); use a heat mat in cooler spots.

Step 1: Prepare Tray

Moisten medium until firm (few drops when squeezed), level the surface, and ensure good drainage.

Step 2: Sow Seeds

Broadcast 7g evenly (1–2 seeds per sq cm) by hand or sifter. Press lightly and mist without burying.

Step 3: Germinate (Blackout Phase)

Cover with a dome or inverted tray. Keep in a dark, warm spot for 3–5 days — mist if dry, watch for white hooks emerging.

Step 4: Introduce Light

Uncover and provide 12–18 hours of intense light (200–400 PPFD). Bottom-water 300–400ml every 2–3 days.

Step 5: Grow Out

Maintain 21–24°C day / 18°C night with constant airflow. Add vermiculite if needed. True leaves appear in 5–10 days.

Step 6: Harvest

Harvest at 2–4 inches with 2–4 true leaves (total 7–16 days). Yields 340–510g per tray.
