GROW!T Loose Coco Coir, 1.5 cu ft

Washed and Buffered Loose Hydroponic Growing Medium, 1.5 cu ft

Raw coco coir carries enough natural sodium that feeding a full nutrient program into it right away can lock out other cations and stall early growth, so growers either wait out an unbuffered medium or take on the extra step of buffering it themselves. GROW!T Loose Coco Coir is a 100% coco coir medium with no additional substrates, washed and buffered to displace sodium and bring ppm/EC levels down before it ever reaches the bag.

Because it's already washed and buffered, this 1.5 cu ft bag lets growers apply nutrients and supplements the same day they plant, without a separate pre-treatment step for a soilless medium with low EC and stable pH.

Key Features & Benefits

• 100% Coco Coir — no additional substrates mixed in.
• Washed and Buffered — displaces sodium for low ppm/EC readings.
• Stable pH — supports consistent nutrient uptake from planting onward.
• Same-Day Feeding — apply nutrients and supplements right after planting.

Who Should Use GROW!T Loose Coco Coir, 1.5 cu ft

This bag fits hydroponic growers who want a ready-to-use, loose coco coir medium without an extra buffering step, since the low EC and stable pH mean nutrients can go in on planting day rather than after a waiting period.

Frequently Asked Questions

Is this coir pre-buffered?

Yes, it's washed and buffered to displace sodium and bring ppm/EC levels down before packaging. That pre-treatment is what allows immediate nutrient application rather than requiring growers to buffer it themselves.

When can I add nutrients after planting?

Its low EC and stable pH support applying nutrients and supplements the same day you plant. There's no waiting period needed to let sodium leach out first.

Is anything else mixed into this coco coir?

No, this is 100% coco coir with no additional substrates blended in. It's sold as a loose-fill medium rather than a pre-mixed blend.

What size bag is this?

This listing is a 1.5 cu ft bag of loose coco coir. It's sized for growers who want to fill containers or hydroponic trays without handling a full compressed block.
