## Overview

The Nutrifield Coco Mega Brick is an 11 lb pre-buffered coco coir growing medium that meets RHP standards, ensuring high purity and performance. Designed to prevent nutrient lockout, it offers superior water retention and an odorless, lightweight experience, making it ideal for professional seed starting and sustainable cultivation.

## Description

Nutrifield Coco Mega Brick is your ultimate pre-buffered natural growing medium. This guarantees the best start for any cultivation. Pre-buffered to prevent calcium and magnesium lockout. Lockout occurs due to the coco coir having a negative charge complex that is surrounded primarily by Sodium and Potassium.

Review: This is going to be my go-to for when I start my seedlings each year going forward. This does a great job holding onto water as compared to the garden variety bagged seed starting mix that you get from a box store. All of my seeds that I have planted this year in this medium have thrived. The block that you get is a great size and you do not need to use a lot for when you start your seeds. The coco coir block does not have a smell and is not heavy at all. It does take a little bit of chipping away to break off pieces to use, but other than that it is a great product. Highly recommend this for anyone who is starting seeds for their flower or vegetable gardens.
Review: Good soil amendment for gardening- particularly for starting seeds or using in pots. Breaks apart easily when left to soak for a bit in warm water. I go through a decent amount of this so I appreciate the value of the large bricks.

*by R***. on 21 July 2025*

Excellent product. Second purchase, consistent quality, good blend of pith and coir. I use it in a drain to waste system and it works great. it is buffered, but you will need to add calmag right away because it looses the cations quick
