|Pour Expanded Shale into grow bed and level. To reduce evaporation and algae growth, keep maximum flood level 1″ below the surface.
||Like traditional soil, dig a hole and place seedling in hole. (Rinse dirt from roots if started in soil.) Carefully backfill hole. If seeding directly, following seeding instructions on package.
||Keep Expanded Shale moist until roots develop or seeds sprout. Flood nutrient water every 1-1.5 hours for 10-15 minutes. Flood more frequently under hot conditions.
