Strawberry is one of the most popular hydroponic crops in India — and for good reason. With the right substrate and consistent EC management, commercial growers across Mahabaleshwar, Himachal Pradesh, and Ooty are producing premium-quality berries year-round.
This guide walks you through substrate setup, EC and pH management by growth stage, and the most common problems Indian strawberry growers face.
Strawberry is a shallow-rooted, moisture-sensitive crop. It needs consistent moisture at the root zone — any dry period during flowering or fruiting directly reduces fruit size and uniformity. At the same time, it cannot tolerate waterlogging. The substrate must balance both.
| Crop type | Annual/perennial berry — typically run as an annual in Indian conditions |
|---|---|
| Crop cycle | 6–8 months crop cycle |
| Growing system | Hydroponic growbag — 100×20×12 cm |
| Growing regions | Mahabaleshwar, Himachal Pradesh, Ooty, Kashmir Valley, Nainital |
| Season | North India: Plant Oct–Nov, Harvest Jan–Mar |
| Farm types | Small polyhouse to large commercial operations |
Strawberry needs high water holding capacity — it is a moisture-loving crop with shallow roots that cannot buffer long dry periods. At the same time, it needs adequate drainage to prevent root rot. AquaHold (100% coco peat) is the primary recommendation.
| Recommended blend | Kultyv AquaHold (100% coco peat) — maximum WHC |
|---|---|
| Alternative blend | Kultyv RootPrime (70:30) for warmer zones with higher irrigation frequency |
| Growbag size | 100×20×12 cm — designed for strawberry’s shallow root system |
| Wash grade | Triple Washed — EC < 0.5 mS/cm (strawberry is very salt sensitive) |
| Substrate EC target | < 0.5 mS/cm before planting |

Step 1. Place Kultyv AquaHold blocks in the 100×20×12 growbag.
Step 2. Rehydrate slowly with clean water — EC < 0.5 mS/cm, pH 5.8–6.0. Add 4–5 litres per kg.
Step 3. Allow 15–20 minutes for full rehydration and expansion.
Step 4. Check substrate EC — should be < 0.5 mS/cm. If higher, flush with more clean water.
Step 5. Check substrate pH — target 5.5–6.0. Adjust with pH-up or pH-down as needed.
Step 6. Pre-buffer with Cal-Mag (2 mL/L) — soak 30 minutes, drain, then plant.
✓ Substrate EC must be below 0.5 mS/cm before planting — strawberry roots are highly sensitive to salt.
✓ Use the 100×20×12 cm growbag — a minimum of 2 litres of substrate per plant is recommended for commercial strawberry.
✓ Never compact the substrate when filling growbags — keep it loose for adequate AFP.
Strawberry EC management changes significantly between vegetative growth and fruiting. Too high EC during establishment damages young roots. EC is raised gradually as the plant develops. Consistent pH around 5.8–6.0 is essential for calcium uptake — which prevents blossom end rot and tip burn.
| Growth Stage | Target EC | Target pH | Notes |
|---|---|---|---|
| Transplant (first 2 weeks) | 0.8–1.2 | 5.8–6.0 | Very low EC to avoid transplant shock |
| Vegetative growth | 1.2–1.5 | 5.8–6.2 | Gradual increase as plant establishes |
| Flowering | 1.5–2.0 | 5.8–6.0 | Consistent EC — fluctuation causes flower drop |
| Fruiting | 1.8–2.5 | 5.8–6.2 | Higher EC concentrates sugars in fruit |
✓ Keep EC consistent during flowering — any sudden rise or drop can cause blossom drop.
✓ Higher temperature = lower EC. In hot months, reduce EC by 0.3–0.5 mS/cm to compensate.
✓ Measure leachate EC at least twice a week during peak fruiting. Target leachate EC: 0.5 above irrigation EC.

These are the most common issues strawberry growers face when using coco peat substrate — and how to address them.
Cause: Sudden EC fluctuation or moisture stress during flowering causes plants to abort developing flowers.
Fix: Maintain steady EC 1.5–2.0 mS/cm during flowering. Ensure substrate never dries out between irrigations — AquaHold’s high WHC helps significantly.
Cause: Calcium deficiency caused by inconsistent moisture or high root zone EC blocking Ca uptake.
Fix: Maintain pH at 5.8–6.0 for optimal calcium availability. Reduce EC if above 2.5. Ensure consistent irrigation frequency — avoid long dry gaps.
Cause: Overwatering in warm conditions creating anaerobic root zone. More common in summer polyhouse setups.
Fix: Reduce irrigation frequency. Ensure growbag drainage holes are open and clear. Consider switching to RootPrime (70:30) in warmer growing periods for better drainage.
✓ Remove runners regularly — runners drain energy from the mother plant and reduce fruit production.
✓ In warmer months, increase irrigation frequency rather than EC — keep the substrate moist without excess salt.
✓ Flush substrate with clean water once every 3–4 weeks to prevent salt buildup.
✓ Use a drip emitter per plant — not a single dripper per bag — for even moisture distribution.
✓ Check strawberry substrate EC at transplant. If above 0.5 mS/cm despite using washed grade, flush again before planting.
