Wheatgrass Grow Kit 2 – Seeds, Trays & Fertiliser

Wheatgrass Grow Kit 2 includes the seed, tray system, paper liners and liquid fertiliser required for repeated wheatgrass crops. You will need to supply your own suitable growing medium.

What You Need

Included in the kit:

• 3kg wheatgrass seed
• 2 drainable grow trays
• 2 matching solid drip trays
• 20 paper tray liners
• 250ml liquid fertiliser
• Growing instructions

You will also need:

• Coco fibre, quality seed-raising mix or another suitable growing medium
• Clean drinking-quality water
• Bowl, jar or container for soaking seed
• Clean scissors or knife for harvesting

Seed Quantity

Use approximately 150–200g of dry wheatgrass seed per grow tray as a practical starting point.

Adjust the quantity slightly according to seed size, growing medium and your preferred crop density.

Aim for dense, even coverage without creating thick overlapping piles of seed, as excessive density can restrict airflow.

Step 1 – Rinse & Soak

1. Measure approximately 150–200g of wheatgrass seed.
2. Rinse thoroughly with clean, cool drinking-quality water.
3. Cover generously with fresh water.
4. Soak for approximately 6–12 hours.
5. In warmer conditions, the shorter end of the range is generally sufficient.
6. In cooler conditions, a longer soak may be appropriate.
7. Drain completely after soaking.

Step 2 – Pre-Germinate

1. Leave the drained wheat in a clean container for approximately 12–24 hours.
2. Rinse and drain during this period as required to keep the seed moist and fresh.
3. Sow once small white roots begin emerging.
4. Do not allow the roots to become excessively long or tangled before planting.

Step 3 – Prepare the Tray

1. Start with a clean drainable grow tray.
2. Place one paper liner flat across the bottom of the tray.
3. Add approximately 1–2cm of coco fibre, soil or another suitable growing medium.
4. Level the surface without compacting it heavily.
5. Place the drainable grow tray inside the matching solid drip tray.

Step 4 – Sow the Wheat

1. Spread the pre-germinated wheat evenly across the growing medium.
2. Aim for dense coverage without excessive overlapping.
3. Water thoroughly.
4. Allow excess water to drain through the upper tray into the drip tray below.
5. Empty excessive standing water where necessary.

Step 5 – Cover During Early Growth

1. Place a second paper liner directly over the freshly sown wheat.
2. Mist the paper until it is evenly damp.
3. Keep the paper and seed moist during early germination.
4. Check regularly rather than allowing the paper to dry completely.
5. Remove the upper liner once the young shoots begin lifting it.

Step 6 – Light & Watering

Once the covering has been removed:

• Move the tray into bright indirect light.
• Avoid prolonged hot direct sunlight.
• Maintain good airflow around the crop.
• Keep the growing medium evenly moist without waterlogging it.
• Once a healthy root mat develops, begin bottom watering through the solid drip tray.

Bottom Watering

To bottom-water established wheatgrass:

1. Lift the drainable grow tray briefly.
2. Add a moderate amount of clean water to the solid drip tray.
3. Replace the upper tray.
4. Allow the roots and growing medium to absorb moisture through the drainage openings.
5. Check moisture regularly.
6. Avoid leaving the crop continuously sitting in excessive water.

Water requirements will vary according to temperature, airflow, crop size and growing medium.

Step 7 – Optional Fertiliser

Additional fertiliser is not always necessary.

If using the supplied liquid fertiliser:

1. Follow the dilution and application instructions on the fertiliser label.
2. Do not exceed the recommended concentration.
3. Use only where additional nutrition is appropriate for the growing medium.
4. Never apply concentrated fertiliser directly to young wheatgrass.

A nutrient-containing growing medium may provide sufficient nutrition for the relatively short wheatgrass growing cycle.

Step 8 – Harvest

Wheatgrass is generally ready to harvest approximately 7–10 days after sowing, depending on growing conditions and your preferred harvest stage.

The grass will typically have developed dense, upright green blades by this stage.

To harvest:

1. Use clean scissors or a sharp knife.
2. Cut the wheatgrass just above the growing medium.
3. Avoid cutting into the growing medium or root mat.
4. Wash harvested wheatgrass thoroughly under cool running drinking-quality water before use.
5. Use promptly after harvesting.

Staggering Two Crops

The two-tray system allows you to maintain overlapping wheatgrass crops.

For example:

1. Start the first tray normally.
2. Begin the second tray several days later.
3. Harvest the first crop when ready.
4. Clean and prepare that tray for another crop.
5. Continue rotating the two trays as required.

This can provide a more regular supply than starting both trays at the same time.

Cleaning Between Crops

After harvest:

1. Remove the wheatgrass root mat.
2. Dispose of the spent growing medium and used paper liner.
3. Empty all remaining water from the drip tray.
4. Wash both trays thoroughly.
5. Rinse with clean water.
6. Allow the trays to dry completely before beginning another crop.
7. Use fresh growing medium and a new paper liner for each crop.
