## Overview

The Canna Coco Brick is a premium, natural coco coir substrate that expands from 8 liters dry to 40 liters when hydrated. Pre-rinsed to reduce salt content, it offers excellent drainage and aeration, making it ideal for indoor and outdoor gardening. Packaged in a reusable, easy-carry bag, this eco-friendly medium supports healthier root growth and can be mixed with pearlite for optimal plant performance.

## Description

Premium fine compressed Canna CoCo into block, not steamed. Pre-rinsed for salt content. Packaged in easy to use plastic bag with carry handles. One CANNA COCO Brick makes 20 liters (0.7 cu. ft.) of coco medium.

Review: First time growing vegetables indoor with this product. I’ve used soil bases before and this product is much better. It does not compact like soil and if you mix it with 15-20 percent pearlite and water till 10 to 20 percent run off, it holds well. You can separate the block in half and that will give you enough mix coco/pearlite and that will fill a 3 gallon planter to about 1 inch from the top. So you can get 2, 3gallon planters from one coco brick plus the pearlite for drainage and retention.
Review: It's very convenient to get these in bulk,add water wait a few minutes and you are ready to go

## Questions & Answers

**Q: How many of these 40L would it take to fill 4, 5 gallon buckets?**
A: Two of these will fill four grow bags that are 5 gallon size very well.    Inside there are two dried bricks that are meant to break in half as needed, making a total of four squares half the length and the same width as shown.     Each of the four squares in the package will fill a 3 gallon grow bag, or two each in two separate 5 gallon grow bags or the whole package fills one ten gallon grow bag.      

I recommend going twice as large as you think you need.     One 10 gallon works better than two 5 gallons if it fits.     I would try two 10 gallons instead and let them live a little and reach capacity easier while draining better so that you can water them "just what they need" everyday instead of all they can handle every two or three days.    Drier is better.    Daily helps more.     Watering modest amounts daily adds more total water volume so you can get by on lower ppms while increasing uptake and keeping it so dry it is never too wet.    Ent wisdom!

**Q: If i soak this in boiling RO water will it kill any fungus gnats it comes with? i read in the reviews that some may contain fungus gnats**
A: Never had that problem.  I soaked it in water and liquid fertilizer. Plants took off quickly. This stuff is really clean.

**Q: Do i use regular water to expand the coco or must i use a mix of full strength nutrients. i was told i'm not supposed to expand it with just water?**
A: I've used coconut coir for 2 outdoor gardening seasons.  I blend with various compost and vermiculite and fill buckets or grow bags. I expand the brick with rain water or tap water that I have allow to sit for a day or two. When I make my blend I add organic feritilizer to the mixture but don't expand the brick with a mineral/fertilizer/nutrient rich solution. That being said, what you use would probably depend on your purpose.

**Q: What is the dry weight of the bricks?**
A: about 8lbs

It’s not just the coco that canna makes that’s great. They are well studied and create top to bottom nutrients that work fantastic together. This is well worth the price. I usually put a few bricks in a large storage bin and water then cover for a night. The next day it breaks down into a beautiful substrate. Add some perlite and you’ll have one of the best mediums you can grow in. It’s honestly relaxing to break down after an overnight bin. It’s smells rich and clean. Big fan of everything I have used from Canna. Thankful I found them early on and have never felt the need to look elsewhere. I don’t think there’s another coco that can compete with them.
