Hydrofarm's Dirt Pot Box offers value and versatility, whether they are used for raised bed gardens or as tray liners for hydroponics systems. Featuring porous breathable fabric, they allow your plants to thrive by promoting exceptional root health and vigorous growth. While these work well outdoors, they also fit standard hydroponics trays for use indoors. The Dirt Pot Box is stronger than similar products, with a PVC frame that supports the entire structure.

Flow rates of RO systems are based on source water @ 65 psi / 77° / 500 ppm

RO output depends on the source water temperature. At 77°, the system should produce 100% of the rated output. As the temperature drops or increases, so does the output

Our best-selling High-Flow system just got better! Improved Dry Membrane design now with 20% increase in flow rate. Up to 1,200+ GPD!

• Capable of producing more than 1,200 GPD (gallons per day) or 50+ GPH (gallons per hour) of pure water, perfect for medium to large hydroponic operations (Flow rates of RO systems are based on source water @ 65 psi/77°/500 ppm)
• Highest flow rates and the most efficient system in the industry!
• Lowers parts per million (ppm) of total dissolved solids (TDS) by 95%+
• SAVE MORE WATER by running a 1:1 waste to product water ratio
• Includes ChloraShield™ carbon filter for 100% chloramine removal

The Hydro Logic Replacement GreenBlock Coconut Carbon Filters are made using high performance coconut shell green carbon which has more micro pores compared to other types of carbon and features a unique binder system delivering a product with superior absorption capacity and kinetic dynamics.

Use this to replace your carbon filter for the Hydro Logic Merlin filtration units.

• Rated at 2 GPM
• Replace after 1,500 gallons

• 98+% PPM Rejection
• 1 membrane for stealth-RO150 and 2 membranes for the stealth-RO300
• Filters up to 150 GPD (gallons per day)
• Replace between 6 months to 2 years

THERE ARE TWO INDICATIONS AS TO WHEN TO CHANGE YOUR MEMBRANES

1. Test the RO and source/inlet water to see what percentage of the inlet water’s PPM the Stealth-RO150 is filtering out (rejection %). You should see approximately 98% of the inlet PPMs being removed when the membrane is new. If the rejection % falls under an acceptable level (typically 90%) it’s time to change the membrane
2. When the flow rate of the product water slows down significantly. This can also happen if your pre-filters are clogged. If you change your pre-filters and the product water still flows slowly then it’s an indication you need a new membrane. When it doubt contact HydroLogic
