Stage Guide

1 / 5

Germination

Usually 5–10 days.

Two long, narrow seed leaves open while a pale root extends through the plug.

  • WaterBegin at 16 fl oz. At about 8 fl oz, add plain water back to 16 fl oz.
  • NutrientUse 0.5 mL per 16 fl oz at setup; do not add another dose during germination.
  • LightProvide 12–14 hours of grow light daily; reseed empty holes on day 10.
  • What to doKeep the plug evenly moist. Check for sprouts from day 5 through day 10; reseed empty holes on day 10 without disturbing nearby seedlings.
  • Ready for next stageAt least one seedling has opened its seed leaves and is beginning to produce true leaves.

Rules That Apply at Every Stage

  • Provide 12–14 hours of grow light daily, followed by 10–12 hours of darkness.
  • When the jar reaches about 8 fl oz, add plain water back to 16 fl oz. Never exceed 16 fl oz.
  • Refresh the nutrient solution every 2–3 weeks; add the stage-specific nutrient dose only during a complete refresh.
  • Between complete refreshes, add plain water only; do not add extra nutrient.
  • Keep the cork sleeve on to shade roots and the reservoir, and rotate the jar one-quarter turn weekly.
  • Shake ClearGro Indoor Plant Nutrient (3-2-5) before every use.
  • Maintain 60–75°F (16–24°C); sustained temperatures above about 75°F (24°C) may accelerate bolting. Use ordinary indoor airflow and keep the plant away from heating or cooling vents.

Harvest & Regrow

Harvest outer stems

Cut outer stems near the base; preserve the center and healthy foliage.

Support regrowth

Harvest moderately; restart when bolting persists.

5

Regrow or Restart

Option A — Continue the same plant

Continue selective harvesting while preserving healthy foliage and the plant's growing points. At the next complete refresh, use the established-plant dose for this crop. Replace the plant if growth becomes weak, leaf quality declines, or root health deteriorates.

Option B — Start a new cycle

Discard the old plant, plug, and roots. Wash and rinse the jar, band, net pot, and wick. Install a fresh plug and seeds, then return to the setup steps. Do not reuse the old plug.

Troubleshooting

No sprout by day 10

Confirm 60–75°F (16–24°C), the 12–14-hour light schedule, and the 16 fl oz maximum water level. Place one fresh seed in each empty hole on day 10.

Tall, weak seedlings

Increase usable light, rotate the jar weekly, and retain only the strongest 2–3 plants.

Yellow or pale leaves

Check light, roots, water level, and the stage-specific ClearGro 3-2-5 schedule; do not add an unplanned dose.

White fuzz or mold on plug

Remove visible growth gently, improve airflow, and avoid pouring water onto the plug. Replace the plug if growth is widespread or seedlings decline.

Brown, slimy roots or odor

Wash the jar and replace the solution if roots are badly damaged; keep the reservoir shaded and never exceed 16 fl oz.

Green algae

Keep the cork sleeve on and block light from the reservoir; clean the jar during a complete refresh.

Early bolting

Keep temperatures at 60–75°F; sustained temperatures above about 75°F may accelerate bolting. Harvest outer stems and restart if bolting persists.

Leaf growth stalls

Check water level, light, and stage-specific nutrient dosing; add plain water only between complete refreshes.

Leaf edges look scorched

Increase distance from the grow light and confirm the nutrient was measured correctly.

Simple Weekly Check

  • Confirm the light timer works and leaves do not touch the lamp.
  • Keep water between the 8 fl oz action point and the 16 fl oz maximum fill level.
  • Check that roots are pale and fresh-smelling, not brown, slimy, or foul-smelling.
  • Retain the crop-specific number of healthy plants and remove only weak or crowded growth.
  • Use the stage-specific nutrient dose only at setup or complete refreshes.
  • Keep the sleeve on and remove flower buds promptly when the guide recommends it.
