How To Grow Sunflower Shoot Microgreens Indoors
11 Easy steps for growing your own sunflower shoot microgreens indoors.
- Measure 2-3 cups of dry seed per 1020 grow tray.
- Sanitize your sunflower seeds by submerging them in The Poor Man’s Sanitizer Solution for 10 minutes. Sunflower seeds float so agitate the soluion a few times.
- Pour the sanitized sunflower seeds into a mesh strainer to rinse well with potable water.
- Pour the sunflower seeds into a tall pitcher or bowl, submerge in pH 6-7 water and soak for 4-12 hours. The seeds will float on the surface so stir occasionally . Remove any floating debris.
- Pour the sunflower seeds into a pasta colander.
- Rinse and drain thouroughly 2x per day. Leave the sunflower seeds in the collander until the root tips are showing.
- Lay the sunflower seeds out on pre-moistened, sanitized grow media in your grow tray. Your seed density should be about 5-8 oz. per 1020 tray and the sunflower seeds should not be clumped together or touching each other.
- Blackout for 2-3 days until shoots start to appear.
- Expose the sunflower seeds to 6500k white light for 18 hours per day, with 6 hours of darkness.
- Water from the bottom up 5-6x per day.
- Harvest your sunflower seeds after 10-14 days when the first or second set of true leaves appear by cutting the shoots just above the grow medium with scissors or a sharp knife. Your sunflower shoots should be 3-4″ inches or more in height by this time.
Your freshly harvested Sunflower Shoot Microgreens should be stored in a closed container in the refrigerator @ 36-40° and will keep for up to 10-14 days.
