House & Garden Coco, 50 L (1.75 cu ft)

A Buffered, Washed Coco Coir Growing Medium, 50L

Unbuffered coco coir can tie up calcium and magnesium as it breaks in, leaving new plantings short on both nutrients right when they need them most, and coir that hasn't been washed thoroughly can carry enough residual salt to throw off an early feeding schedule. House & Garden Coco is a 100% coco coir growing medium that's buffered and washed before packaging to bring its starting EC/ppm down, then sifted to remove sand and fine dust that would otherwise clog drip emitters or compact the medium.

This 50 liter (1.75 cubic foot) bag is sized for a full container run or grow-bag setup. Because the starting EC is low, House & Garden recommends feeding with a base nutrient program right after planting rather than watering with plain water first, and blending in up to 30 percent perlite adds extra drainage for heavier feeding schedules.

Key Features & Benefits

• Buffered coco coir — reduces the calcium and magnesium tie-up that raw, unbuffered coir can cause as it breaks in
• Washed for low starting EC/ppm — lets growers begin feeding right after planting instead of running plain water first
• Sifted to remove sand and fine dust — helps keep drip emitters clear and the medium from compacting over time
• 100% coco coir — an organic, renewable growing medium with strong water-holding capacity relative to soil
• 50L (1.75 cu ft) bag — sized for a full container run or grow-bag setup

Who Should Use House & Garden Coco

Growers running coco coir as a standalone medium or blended with perlite, in containers, grow bags, or hydroponic troughs, will benefit from starting with a pre-buffered, pre-washed bag rather than buffering raw coir themselves.

About House & Garden

House & Garden is a nutrient and additive brand established in 1990 by William Van De Zwaan, whose family had a background in Dutch horticultural glasshouse production; the company formulates its base nutrients and additives in small batches, filtering its process water through multi-stage ceramic filtration. Hydrofarm acquired House & Garden in 2021, and the brand's manufacturing and research operations are based in Humboldt County, California, building a product line of base nutrient systems and root, flowering, and growth additives sold to growers in dozens of countries.

Frequently Asked Questions

What size does this coco coir come in?

This listing is a 50 liter (1.75 cubic foot) bag of House & Garden Coco. That size is sized for a full container run or grow-bag setup.

Why is the coir buffered and washed before it ships?

Raw, unbuffered coco coir can tie up calcium and magnesium as it breaks in, and unwashed coir can carry enough residual salt to skew an early feeding schedule. Buffering and washing the coir before packaging addresses both issues so the medium starts closer to neutral.

Do I need to feed this coco coir right away?

Yes. Because the starting EC/ppm is already low, House & Garden recommends beginning a base nutrient feeding program right after planting rather than watering with plain water first, since coco coir doesn't hold nutrient reserves the way soil does.

Can I mix this coco coir with perlite?

Yes, blending in up to 30 percent perlite by volume adds extra drainage and aeration. This is useful for growers running a heavier feeding schedule or a system that waters more frequently.

How is this different from raw, unwashed coco coir?

Raw coco coir typically needs to be soaked, buffered with a calcium source, and rinsed before use to bring salt and pH levels into range. This product ships already buffered, washed, and sifted, so it's ready to fill containers directly from the bag.
