How to Grow Fresh Sprouts
at Home
Nutrient-dense sprouts on your kitchen counter. No garden, no experience, no fuss.
What You Need
A jar, a lid, a way to drain, and seeds. That's it.
Wide-Mouth Jar
Ideally a quart-size mason jar. Gives seeds room to expand.
Mesh Lid
Stainless steel mesh for rinsing and draining. Cheesecloth works too.
Stand or Tray
Prop the jar at a downward angle so water drains completely.
Sprouting Seeds

4 Steps to Fresh Sprouts
Works for every Seedboy variety. Check the chart below for timing by seed type.
Soak Your Seeds
Add 2 tablespoons of seeds to your jar. Cover with cool water, at least 2 inches above the seeds. Mesh lid on top. Soak 4 to 6 hours or overnight. Larger seeds (mung bean, sunflower) need 8 to 12 hours.
Cool water (not cold, not warm) gives the most consistent germination.
Drain and Rinse
Drain all water through the mesh lid. Rinse with fresh, cool water. Swirl gently, drain thoroughly, shake out excess. Prop the jar upside-down at an angle so it keeps draining.
Standing water is the #1 cause of mold. The jar should feel damp, not wet.
Rinse and Repeat
Rinse and drain 2 to 3 times per day. Morning and evening minimum. Keep the jar somewhere with indirect light and decent airflow. Avoid direct sunlight.
Tiny white tails appear within 24 hours. By Day 3, the jar starts filling up.
For sweeter sprouts, keep the jar in a dark spot. Give a few hours of indirect light right before harvest to green up.
Harvest and Enjoy
Harvest at 2 to 3 inches. Final rinse. To remove hulls, transfer sprouts to a large bowl of water and swirl. Hulls float to the top, unsprouted seeds sink. Skim, lift, and drain.
Toss into salads, sandwiches, wraps, smoothies, stir-fries, grain bowls, or eat straight from the jar.
Sprouts taste best the day they are harvested. Grow only what you will eat in a few days, then start another jar.

Tips for Better Sprouts
Small adjustments, big difference.
Temperature
65 to 75°F is the sweet spot. Too warm = slimy. Too cold = slow. Kitchen counter, out of direct sun.
Airflow
Stale air breeds mold. Keep the jar propped at an angle so air flows through the mesh. Avoid enclosed cabinets.
Stagger Your Jars
Start a new jar every 2-3 days for a constant supply. Rotate varieties for different flavors and nutrients.
How to Store Your Sprouts
Handle them right and they stay crisp for up to a week.
Final rinse. Bowl of water, swirl, skim off floating hulls.
Drain well. Pat dry or salad spinner. Less moisture = longer life.
Sealed container with paper towel lining to absorb moisture.
Refrigerate. Enjoy within 5-7 days for peak freshness.
Troubleshooting
Not enough rinsing or drainage. Increase to 3 rinses per day and make sure the jar drains at a full downward angle. If the smell is strong, start fresh.
Probably root hairs, which are normal. Fine white fuzz at root tips, especially on broccoli, alfalfa, and clover. Mold is gray or black, smells musty, and sits on the sprouts themselves. Root hairs rinse away. Mold does not.
Totally normal. Fenugreek and blends containing it (Hormone Balance, Gut Health) release a yellow pigment. It can stain light surfaces, so rinse over the sink.
A small percentage is normal. If more than 20% fail, confirm you are using seeds labeled for sprouting. Check the expiration date and soak time.
Drainage and temperature issue. No water pooling at the bottom. Keep out of warm spots. Rinse more often with cooler water.
At 2-3 inches when leaves have opened. Taste along the way. Earlier = milder, longer = more developed. No exact "done" moment.
Yes, if they have similar soak and sprout times. That is what our blends are designed for. Avoid mixing fast sprouts (fenugreek, Day 4) with slow ones (sunflower, Day 8).
