TLDR:
Dry coco bricks are hydrophobic (repel water) and must be re-wet before planting. To get coco bricks ready for planting:
- Pre-soak with warm water to expand the brick.
-
Rinse and check pH/EC for stability.
- Use Samurai Coco featuring AquaZen for superior water distribution, consistent moisture, and healthier root growth.
Bottom Line: Skip the headaches of ordinary coco — choose Samurai Coco + Shogun CalMag for the perfect start.
Why Coco Bricks Repel Water
When coco dries out completely, natural waxes coat the fibres, causing it to repel water. If you pour water straight onto a dry brick, it will bead and run off instead of soaking in.
The solution is simple: once rehydrated, coco transforms into a water-friendly medium that distributes moisture evenly across the root zone and provides the perfect balance of air and water for roots.
Step 1: Pre-Soak and Expand the Brick
- Place your dry coco brick in a large container or bucket.
- Slowly add warm water — this breaks down the waxy coating faster.
- Break apart clumps as the brick expands, making sure there are no dry pockets left.
- Let it soak for at least 30–60 minutes.
Bottom Line: Pre-soaking is essential. Skipping this step leads to uneven wetting, poor root establishment, and unstable nutrient delivery.
Step 2: Rinse and Check
Most coco available in reputable grow shops today comes pre-buffered — meaning the excess sodium and potassium have already been replaced with calcium and magnesium. This removes the need for time-consuming buffering at home.
After rehydrating:
- Rinse lightly with clean water.
- Check your pH (aim for 5.5–6.5) and runoff EC. The runoff EC should be close to your input water. If readings are significantly higher then continue rinsing until the numbers drop.
- Once runoff is stable, your coco is clean and ready for nutrients.
Bottom Line: At this point, begin feeding with the Samurai Coco powered by AquaZen, supported by Shogun CalMag, to establish a balanced foundation for strong, healthy growth.
Step 3: Samurai Coco — The Essential Upgrade
Ordinary coco can lead to dry spots, uneven wetting, and inconsistent nutrient delivery. These issues compromise root health and make irrigation less efficient.
Samurai Coco with AquaZen technology eliminates these problems. It ensures superior water flow, faster re-wetting, and uniform distribution across the entire root zone. The results are clear:
- Consistent moisture with less dry-back stress
- More efficient use of every drop of feed
- Stronger, healthier root development
Whether you’re using drippers, fabric pots, or hand-watering, Samurai Coco with AquaZen provides the precision and consistency required for high-performance growing.
Final Thoughts
Rewetting coco bricks is the first step to creating a reliable base for your grow. But the real performance comes from what you feed afterwards. By:
- Pre-soaking properly,
- Rinsing and checking your pH/EC,
- Running Samurai Coco powered by AquaZen, supported by Shogun CalMag
…you’ll give your plants an irrigation-friendly, stable, and highly productive root environment.
Bottom Line: Don’t stop at rehydrating coco — unlock the full potential of your grow with Samurai Coco powered by AquaZen and Shogun CalMag.
