HWS Inner Pot 25L

A Drop-In Inner Pot That Keeps Flood and Drain Cycles Running Cleanly

The HWS Inner Pot 25L is a durable replacement or spare inner pot for HWS (Hydro Water Systems) and IWS flood and drain hydroponic systems. It sits inside the matching 25-litre outer pot, holding your growing medium while letting nutrient solution flood through the root zone and drain away freely on each cycle. A worn or damaged inner pot is an easy route to waterlogging, weak roots and patchy uptake; swapping in a fresh pot restores clean, free-draining flow for stronger growth through veg and flower.

Key Benefits

• Direct fit for HWS and IWS 25L flood and drain systems
• Heavy-duty injection-moulded plastic built for repeated flood cycles
• Free-draining design that supports healthy root development and oxygenation
• Works with clay pebbles, coco or 60/40 mixes, depending on the pot variant
• Prevents waterlogging by draining fully between floods
• Ideal spare or replacement when expanding or refurbishing a system

Fixing Poor Drainage and Root Health in Flood and Drain

A damaged inner pot disrupts drainage, root health and system performance. The HWS Inner Pot 25L lets solution circulate freely around the roots during each flood cycle then drain efficiently, preventing waterlogging, improving oxygen availability and encouraging stronger roots, faster veg and better flowering.

How to Use

1. Place the inner pot inside the compatible 25-litre outer pot.
2. Fill with your chosen growing medium.
3. Transplant your rooted plant into the centre of the pot.
4. Connect to your flood and drain system as directed by the manufacturer.
5. Ensure solution floods and drains freely through the pot each irrigation cycle.
6. Clean the pot between grows to prevent salt build-up and maintain healthy roots.
