Premium Substrates at Reasonable Prices

 At Holland Horticulture we believe that every grower deserves access to the highest quality substrates at prices that won’t break the bank. Whether you’re a seasoned pro or just starting, the foundation for healthy, thriving plants begins with the right growing medium. We’ve made it our mission to provide the best premium substrates on the market, ensuring that your plants get the perfect environment for growth at every stage. Our new, cutting-edge mixes are designed to outshine anything else available, offering growers the ultimate solution for cultivation success.

Why Quality Substrates Matter

The substrate you choose has a direct impact on the health, growth, and yield of your plants. It’s the foundation that supports everything from root development to nutrient absorption. Poor-quality substrates can lead to issues like waterlogging, root rot, nutrient imbalances, and slow growth, all of which can set your plants back and reduce yields. That’s why we focus on delivering only premium substrates, each designed to eliminate common growing challenges while optimizing conditions for vigorous, healthy plants.

The 100% Coco Advantage

If you’re a grower who demands the best, our 100% Coco substrate is a dream come true. This isn’t your average coir—it’s deeply buffered, RHP-certified, and free from any harmful viruses or soil diseases. What does that mean for you? A smooth growing experience from day one. With its perfect pH of 6.0 and ultra-low EC of 0.1, your plants will thrive with enhanced nutrient uptake and faster growth. The superior water retention ensures your plants get the moisture they need without risking overwatering. Ready for use straight out of the bag, no reconditioning required, this is the premium solution for growers looking to take their results to the next level.

Kaizen 70/30: The Best of Both Worlds

For those who want even more versatility, the Kaizen 70/30 mix combines the benefits of coco coir with the added power of perlite. This blend uses 70% RHP-certified coco, ensuring deep buffering and protection against common coir-related issues. The real secret sauce? The 30% perlite. Perlite is a natural aerator, improving airflow to the roots, which prevents compaction and encourages faster, stronger root development. The improved drainage also reduces the risk of waterlogging, a major issue for many growers. With a perfect pH of 6.0 and a low EC, this mix is tailored for both the growth and flowering stages, making it ideal for any type of plant. Whether you’re growing indoors or outdoors, the Kaizen 70/30 blend creates the optimal environment for vibrant, healthy plants.

The Revolutionary Kaizen 50/30/20 Mix: The Future of Substrates

Now, we’re excited to introduce the next evolution in substrates—the brand-new Kaizen 50/30/20 mix. This is the game-changer you’ve been waiting for. It combines the finest 50% RHP-certified coco coir, 30% perlite, and 20% clay pebbles, offering an unmatched balance of water retention, aeration, and drainage.

The 50% coco delivers all the benefits you expect from a premium coir, with its deep buffering and low EC ensuring your plants get exactly what they need. But what really sets this mix apart is the combination of 30% perlite and 20% clay pebbles. The perlite promotes superior aeration and prevents compaction, allowing your roots to breathe and grow rapidly. Meanwhile, the clay pebbles take drainage to the next level, creating the ideal water-to-air ratio—especially important for hydroponic systems or those prone to overwatering.

This unique blend ensures that your plants receive optimal oxygen at the root zone while maintaining just the right amount of moisture, reducing the risk of root rot or waterlogged conditions. With its perfect balance, this mix works wonders across a wide range of growing systems, from hydroponics to soil.

Why This Mix is a Game-Changer

The Kaizen 50/30/20 mix is not just a substrate—it’s the future of plant cultivation. By combining the three most effective growing mediums into one, it solves all the common problems growers face when using coco alone. No more worrying about poor drainage or compacted roots. No more dealing with the hassle of reconditioning. This mix is ready to use straight out of the bag, offering growers the perfect foundation for healthier plants and higher yields, all with minimal effort.

Not only does it deliver superior results, but it also offers peace of mind. Knowing that your substrate has been rigorously tested and RHP-approved means you can trust it to consistently perform, every time you grow. It’s the perfect balance of quality, innovation, and affordability.
