Roots Organics 70/30 Coco & Perlite, 1.5 cu ft

Dolomite-Buffered Coco and Perlite Growing Blend, 1.5 cu ft

A straight coco medium alone can swing pH without a buffering step, and building a custom blend from raw ingredients takes more work than many growers want for a standard container mix. Roots Organics 70/30 combines coco coir and perlite in a 70/30 ratio, naturally buffered with dolomite, for a free-draining medium that still holds enough moisture for fast-growing, heavy-feeding plants.

This 1.5 cu ft bag is sized for growers running a handful of containers or testing 70/30 as a new base medium before scaling up to a larger volume.

Key Features & Benefits

• 70/30 coco-to-perlite ratio — balances moisture retention with drainage.
• Naturally buffered with dolomite — helps stabilize pH before feeding begins.
• Ready to use straight from the bag — no rinsing or amendment step required.
• Free-draining yet moisture-retentive — suited to fast-growing, heavy-feeding plants.

Who Should Use This

Organic gardeners who want a ready-to-use coco and perlite blend, or a base to combine with their own dry amendments, will find this 70/30 ratio suited to that flexibility.

Frequently Asked Questions

What is the coco-to-perlite ratio?

It's a 70/30 blend of coco coir to perlite. That ratio is set at the bag level, so there's no separate mixing step before use.

Is it pH buffered?

Yes, it's naturally buffered with dolomite. That helps stabilize pH going into the container before a grower's feeding program takes over.

Can I use it straight from the bag?

Yes, it's ready to use as a standalone growing medium straight from the bag. Growers can also blend it with their own dry soil amendments to build a custom mix.

What plants is it suited to?

It's suited to fast-growing, heavy-feeding plants that need both drainage and moisture retention. The 70/30 ratio is built to hold enough water for those plants without staying waterlogged.

How does this differ from Roots Organics CocoPalms?

CocoPalms is a straight coco coir medium without added perlite, while 70/30 already blends coco with perlite for a set aeration-to-moisture ratio. Choose 70/30 when you want that ratio built in, or CocoPalms when you want to control aeration yourself with your own amendments.
