Wilma XL 4 (90×90cm) — 70L Tank, 18/25L Pots

Wilma XL 4 (90 × 90cm) — 70L Tank, 18 or 25L Pots

The XL version of the famous Wilma 4-pot system — bigger 70L nutrient tank and larger 18L or 25L pots for handling the biggest plants you can grow. A bestseller for good reason: simple timer-driven drip irrigation that delivers predictable results grow after grow, now sized for serious production.

Why growers choose the Wilma XL 4:

• 90 × 90cm footprint, 4 pots — fits in 1.2m tents with room to spare for access
• 70L nutrient tank — triple the volume of standard Wilma, fewer mid-grow top-ups
• 18L or 25L pots — room for proper root development on large flowering plants
• Improved pot spacing — better airflow between plants, easier management
• Bestseller in the UK hydroponics market — proven design, parts widely available
• Timer-driven feeding — plants fed little and often through the drippers
• Easy access to reservoir — designed for low-fuss maintenance

Who it's not for:

For tighter spaces or smaller plants, the standard Wilma 4 with smaller pots will fit better. For 8 plants in the same footprint approach, see Wilma 8 variants. Needs space for the full 90 × 90cm frame plus reservoir — plan your tent layout accordingly.
