Give your plants the clean start they deserve. The HydroLogic GroGreen Garden Hose Filter connects directly to any standard garden hose and delivers filtered water — removing chlorine, chloramines, sediment, rust, silt, mercury, lead, and PCBs — without any electricity, pump, or permanent installation. Whether you're watering a backyard garden, filling a hydroponic reservoir, or brewing a compost tea, this compact inline filter works quietly in the background to protect your plants and the beneficial microorganisms that make them thrive.
Most tap water contains chlorine and chloramines that can devastate the beneficial bacteria and fungi living in your soil, compost, and bio-teas. The GroGreen uses a dual-media system — KDF85 paired with Granulated Catalytic Activated Carbon — to tackle a broad spectrum of contaminants in a single pass, removing up to 99% of chlorine and chloramines. The customized flow restrictor ensures water spends enough time in contact with the media to maximize reduction effectiveness, so every drop that reaches your plants is as clean as possible.
Rated for an impressive 11,000 gallons (30 GPD = 365 days) and flowing at up to 2 GPM, it's built for real-world garden use — not just occasional watering. The lightweight inline design makes it portable, so you can move it between hose bibs, greenhouses, or grow rooms as needed.
"I've been using this on my raised beds for two seasons now. My compost teas are way more active and my plants look noticeably healthier. The flow rate is solid and I love that I don't have to replace it constantly."
— Marcus T., Organic Vegetable Grower
"Perfect for my small greenhouse setup. Easy to move between hose bibs and the 11,000-gallon capacity means I'm not swapping filters every few months. Highly recommend for anyone running bio-teas."
— Sandra K., Greenhouse Hobbyist
"I run a small hydro operation and water quality is everything. This filter handles chloramines — not just chlorine — which most cheap filters miss. Game changer for my reservoir fills."
— Derek M., Hydroponic Cultivator

What contaminants does the GroGreen filter reduce?
It reduces chlorine, chloramines, sediment, rust, silt, mercury, lead, and PCBs (organic chlorine). KDF85 media also inhibits bacterial and algae growth within the filter itself.
How long does the filter last?
The GroGreen is rated for 11,000 gallons — equivalent to 30 GPD for a full year (365 days). Actual lifespan will vary depending on your water quality and usage volume.
What is the flow rate?
Up to 2 gallons per minute. The built-in flow restrictor is intentional — it ensures adequate contact time between the water and the filtration media for maximum chlorine and chloramine reduction.
Does it remove chloramines as well as chlorine?
Yes. The KDF85 + Granulated Catalytic Activated Carbon combination removes up to 99% of both chlorine and chloramines — making it more effective than standard carbon-only filters for municipal water treated with chloramines.
Does it require electricity or a pump?
No. It connects inline to any standard garden hose and operates entirely on water pressure. No electricity, pump, or permanent installation required.
Can I use this with a hydroponic system or compost teas?
Absolutely. It's specifically designed to protect beneficial bacteria in organic compost, soil amendments, and bio-teas, and is well-suited for hydroponic reservoirs, greenhouses, and container plants.
