OXYPOT BLANKING CAP

Description

OXYPOT BLANKING CAP is the simple but essential accessory for growers using Nutriculture Oxypot DWC systems who want to operate with fewer net pots than the unit’s maximum capacity. We have been supplying Oxypot system components to UK hydroponics growers since 2017, and the blanking cap is one of those small parts that prevents a surprisingly common and frustrating problem — light leaking into the reservoir through unused net pot holes, triggering algae growth that compromises root health and system hygiene.

Why Blanking Caps Are Essential for DWC System Hygiene

Oxypot systems are designed with a fixed number of net pot positions. When a grower chooses to run fewer plants than the system’s maximum — either for larger individual plants that need more space, or during a smaller-scale run — the unused holes expose the nutrient solution in the reservoir directly to light through the gap around the missing net pot. Even indirect or low-level light entering the reservoir is enough to initiate algae development in the warm, nutrient-rich solution, leading to green slime on root surfaces, blocked air stone outlets, and a rapid deterioration in dissolved oxygen levels that can cause root rot. A blanking cap snaps securely into the unused net pot hole and eliminates this light entry completely.

Fitting and Using Oxypot Blanking Caps

Blanking caps are sized to fit the standard Oxypot net pot hole diameter and snap in place without tools. Fit them before filling the reservoir for the first time in any cycle where not all positions will be used. Check that the cap sits flush and fully covers the hole — even a small gap is enough for algae light contamination. Remove and clean blanking caps with each reservoir change to prevent the accumulation of algae or nutrient residue on the underside where they contact the solution surface. Stock several caps so you always have clean replacements available at the start of each cycle.

Keep Oxypot Blanking Caps alongside your Oxypot replacement net pots, air stones, and reservoir cleaning solution for a complete DWC system maintenance kit that keeps your roots clean and healthy from day one.
