Description
Every nutrient recipe starts with the water. Get it clean.
If your source water carries a load of dissolved solids — and municipal, well, and most surface water all do — you’re fighting a moving target every time you mix nutrients. Background calcium, magnesium, sodium, and chlorides stack on top of what you’re dosing, throw off your EC, and leave you guessing at what the plant actually gets. Reverse osmosis gives you a blank slate: strip the water down, then build your recipe up exactly, batch after batch.
The FMV series is our high-efficiency line — engineered for a low reject ratio, so you turn more of your feed water into usable permeate and send less down the drain. In a facility running thousands of gallons a day, that water savings is real money, and it’s the difference between an RO system that pays for itself and one that just runs up your bill.
Size it to your daily demand. Seven capacities from 1,800 to 14,400 GPD. The right pick depends on your canopy, your irrigation events per day, and your storage — undersize it and you’re waiting on the tank; oversize it and you’ve tied up capital you didn’t need to. Frame-mounted and skid-ready for a clean install against a wall or in a mechanical room.
Not sure which capacity matches your grow? That’s exactly the kind of sizing we do every week — tell us your canopy and daily water budget and we’ll spec it. Water treatment is the front half of good fertigation, and we build both.
