01 / Super washed
Six washes, EC under 0.6.
The coco is washed six times to strip salts, fine particles, and impurities, finishing below 0.6 mS/cm. You start from a clean, predictable baseline instead of fighting the media.

Why LooseFill
Clean coco, measured and proven.
Same coco peat that goes into QuickFill, in a loose bag you fill your own way. Washed six times, held to a low EC, and tested every batch so the medium behaves the same from one pallet to the next.
02 / Lab verified
Heavy metals: not detected.
Every batch runs an ICP-MS heavy-metals panel — arsenic, cadmium, lead, and mercury all return Not Detected at a 0.05 mg/kg limit. CDFA-approved input, traceable to its test report.
03 / Ready to use
Open, fluff, and plant.
No rinsing, no re-hydrating a compressed brick. Loosen the bag, saturate to runoff, and plant. Buffered blends go a step further and arrive pre-charged for day-one feeding.
04 / Fertigation ready
Built for drip and recirculation.
High porosity and stable air space make LooseFill a clean fit for hydroponic systems, drip irrigation, and high-frequency fertigation — pair it with FloraFlex dry nutrients and drippers.

How to use
Open the bag. Start growing.
LooseFill drops into pots, grow bags, beds, and hydroponic systems. Four steps from pallet to planted — and the same coco pairs cleanly with FloraFlex dry nutrients and drippers.
01
Prepare
Open the bag and loosen the coco if compacted. Fluff to aerate and break up any clumps.
02
Plant
Use the media directly in pots, grow bags, beds, or hydroponic systems — no rinsing required.
03
Hydrate
Saturate with clean, pH-adjusted water or nutrient solution until runoff to prime it for planting.
04
Monitor
Keep a regular feed schedule and watch moisture. Avoid letting the coco dry below ~20% VWC.

FAQ
Buyer questions, answered.
What growers and resellers ask before they choose a blend and place an order.
LooseFill is FloraFlex's line of loose, bagged coco growing media for growers who fill their own containers and systems. It comes in two blends — 100% coco coir at 60% water-holding capacity and a 70/30 coco + perlite blend at 52.5% — both Signature, pre-charged and feed-ready, in 50-liter (1.8 cubic foot) bags.
The 100% coco blend holds more water — 60% WHC — and suits growers who want maximum retention. The 70/30 coco + perlite blend holds 52.5% WHC and adds drainage and aeration from the perlite, which helps in high-frequency fertigation and setups prone to overwatering.
The 100% coco blend holds 60% (±2%) water by volume with about 40% air space, 85% porosity, and 31% aeration. The 70/30 coco + perlite blend holds 52.5% (±2%) by trading some retention for extra drainage and aeration.
Yes. The coco is super-washed to an EC below 0.6 mS/cm and CDFA approved. Each batch runs an ICP-MS heavy-metals panel — arsenic, cadmium, lead, and mercury all return Not Detected at a 0.05 mg/kg limit of detection — traceable to its test report.
Open the bag and fluff the coco to aerate it and break up any clumps, then use it directly in pots, grow bags, or hydroponic systems. Saturate with clean, pH-adjusted water or nutrient solution until runoff before planting, and keep moisture from dropping below about 20% VWC.
LooseFill works across cannabis, vegetables such as tomatoes, peppers, cucumbers, and leafy greens, culinary herbs, ornamentals, and greenhouse crops. It's suited to hydroponic systems, drip irrigation, and high-frequency fertigation, as well as traditional container growing.
Each bag is 50 liters (1.8 cubic feet). Net weight is approximately 22 lb (10 kg) for most SKUs; the 70/30 blend is around 25 lb (11.3 kg). All bags are packaged in the USA and available in pallet quantities for commercial operations.
QuickFill is a pre-filled, pre-drilled grow bag — the bag is the container, and you expand and plant. LooseFill is loose coco in a bulk bag that you use to fill your own pots, beds, or systems. Both use FloraFlex's super-washed, batch-tested coco; LooseFill adds blend and treatment options.
LooseFill is sold through FloraFlex authorized distributors. Use Find a Reseller to locate a stocking partner, or request a quote and FloraFlex routes it to the nearest distributor that carries your products. Bulk and custom quantities are available for commercial-scale operations.
