How to grow it
Scatter tiny seeds on surface — needs light. Mist. Grow light 14-16 hrs. 65-70°F. Germination 14-21 days.
Keep constantly moist. Celery wilts quickly without water. Long season crop — 120-150 days.
Harvest outer stalks individually or cut whole plant at base. Blanch by wrapping stalks with cardboard for lighter color.
