Stage Guide

Germination

Typically 7–21 days.

Seed leaves open above the plug while the first pale root grows downward.

  • 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 14–16 hours under a grow light; keep seeds at the plug surface and reseed empty holes on day 21.
  • What to doKeep the plug evenly moist and the jar cool. Check each hole from day 7 through day 21; reseed empty holes on day 21.
  • Ready for next stageAt least one seedling has opened its seed leaves and is beginning to produce narrow true leaves.

Rules That Apply at Every Stage

  • Provide 14–16 hours of grow light daily, followed by 8–10 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 60–70°F (16–21°C); avoid temperatures below 60°F (16°C). Use ordinary indoor airflow and keep the plant away from heating or cooling vents.

Harvest & Regrow

Harvest flower stems

Cut flower stems just above a leafy green node; keep healthy foliage, avoid woody stems, and remove no more than one-third at a time.

Support regrowth

Remove spent flower stalks and lightly shape green growth, leaving the woody base and lower foliage intact.

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 21

Keep the seed at the plug surface, maintain 60–70°F (16–21°C) and 14–16 hours of light, and reseed empty holes on day 21.

Tall, weak seedlings

Increase usable light and rotate the jar weekly; keep the lamp close enough for strong light but not touching leaves.

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 and improve airflow. 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.

No flower buds

Maximize light and allow the plant to become established and branch; do not add extra nutrient to force flowering.

Flower stems decline

Remove spent stalks, keep lower foliage intact, and avoid cutting into woody stems.

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.
