More about sprouting

Looks a bit complicated, but your shaded rinse table/buckets can be different from your soak table/buckets. I'd use buckets with taps on the bottom, since these can be easily emptied or hung from faucets down stream from a solenoid valve operated by timer. Note that sending the water from the sprout/rinse cycles to the cattle for drinking would give them even more vitamins and nutrients.

Sprouting For Healthier Birds:

"# INSPECT and remove broken and damaged seeds which will not sprout and can cause spoilage.

# RINSE well until the water runs clear.

# SOAK overnight in pure water (and antibacterial solution if desired). Water level should be well above the top of the seeds to allow for swelling. Houseplants can benefit from the nutrients in the soak water.

# RINSE well in the morning.

# SPREAD seeds in colanders, glass jars, or pans and place in a dark, well-ventilated area.

# RINSE well several times a day.

# HARVEST when small tails appear, usually in one or two days.

# DRAIN UNTIL DRY before serving

Field corn: Soak for 12-18 hours. Very hard corn and slow to germinate"

SOIL SPROUTING
Sprouting in soil will produce sunflower "greens," buckwheat greens, fresh pea shoots, or wheat and barley greens. These greens provide variety and a good change from the usual supermarket variety of greens. They sometimes are available in health food stores ready-to-serve. Here are the easy directions for growing nutritious greens in a limited space:

Fill large trays with drainage holes two thirds full of pesticide and chemical-free potting soil. Soak wheat berries for eight hours, peas, buckwheat or sunflower seeds for twelve to eighteen hours and spread loosely over the surface of the soil. Water well and cover with plastic with one side unsealed for ventilation. Water daily with a fine mist. After three days uncover the trays and place them in indirect sunlight or bright indoor light for five to eight days. The crop will be five or six inches tall. Keep the soil moist and cut as needed while the plants are young and tender.
