Crop Guide
Suited for capsicum, aubergine, and berries.
Target EC, drain percentage, and dripper configuration for the three crops this slab is engineered for.
Capsicum & Sweet Pepper
EC target
2.0 – 3.5 in-slab
Drain %
20 – 30%
Configuration
2 drippers/plant; slight generative stress in fruiting phase improves Brix
Aubergine / Eggplant
EC target
2.0 – 3.0 in-slab
Drain %
15 – 25%
Configuration
Long-season crop — flush slab mid-season if EC rises above 4.0
Strawberry
EC target
1.2 – 2.0 in-slab
Drain %
25 – 40%
Configuration
High drain; wide opening allows easy runner removal and root inspection
Drainage Setup Protocol
Pre-saturate. Set drain. Close clean.
Correct slab preparation and drain geometry make the difference between consistent drain percentage and pooling.
01
Pre-saturate
Flood slabs 24 h before planting. Drain to 20–30% of slab volume. Check EC — target < 1.5 mS/cm before introducing nutrients.
02
Drain Holes
Cut 2–3 slits (10 mm) at slab ends on the bottom face. Angle slabs 1–2° toward drain to prevent pooling. Cut after pre-saturation only.
03
Season End
Flush with EC ≤ 0.5 water for 48 h. Spent slab is peat-free and suitable for soil amendment or composting.
