Same Quality as Plagron Cocos Premium
Cocos Brix and Cocos Premium in bag format are identical in quality. Both undergo the same double-rinsing and buffering process that removes all unwanted salts and locks in a low, stable EC. This ensures that Plagron Cocos A&B nutrients are absorbed under optimum conditions from day one, with no pre-treatment required beyond rehydration. The low initial EC also prevents calcium deficiency, a common issue with lower-grade coco substrates.
Versatile Applications Beyond the Main Substrate
Cocos Brix aren't limited to use as a standalone grow medium. Once rehydrated, they can be mixed into existing soil-based substrates to improve structure, water retention and aeration — particularly useful for growers transitioning to coco or looking to upgrade a peat-based mix. Combining Cocos Brix with Plagron Perlite creates an exceptionally airy, fast-draining blend ideal for cuttings, seedlings and high-frequency watering schedules.

Is the quality of Plagron Cocos Brix the same as Cocos Premium in a bag?
Yes, the quality is identical. Both products share the same composition, the same double buffering and rinsing process, and the same EC and pH parameters. The only difference is the format — Cocos Brix are compressed for compact transport and storage, then rehydrated before use. Performance in the grow room is exactly the same.
