Pro-XL Organic Fertilized Substrate – 50L Premium Coco Coir with Humus

The Pro-XL Organic Fertilized Substrate (50L) is the ultimate launchpad for your cultivation, designed to transform the way your roots develop from day one.

Why your plants are begging for a better substrate

Are you tired of seeing your plants struggle to take off during the first few weeks?

There is nothing more frustrating than investing in top-tier genetics and lighting, only to have your plants stall because the root zone is suffocated or lacking essential nutrients. A poor quality medium acts like a straitjacket for your roots, leading to slow growth, nutrient lockouts, and a disappointing harvest that doesn't reflect your hard work. It’s the silent killer of potential yields.

The solution is to switch to a medium that breathes and feeds simultaneously. With Pro-XL Organic Fertilized, you are providing a 5-star hotel for your root system. Its airy structure prevents compaction, while the pre-loaded organic charge ensures your plants have immediate access to food without the risk of nutrient burn. It’s the cheat code for a lush, healthy vegetative stage.

How to use this substrate for maximum results

Using Pro-XL Organic Fertilized is straightforward, but a few pro tips can help you get the most out of it:

1. Pre-moisten: Before filling your pots, moisten the substrate slightly and let it rest for a few hours to activate the structure.
2. Filling: Fill your pots loosely; do not pack it down tight. The goal is to keep it airy.
3. Watering: Since it holds water well, be careful not to overwater initially. Keep it moist, not soaking wet.
4. Fertilization: This substrate has a base charge. You generally won't need to add heavy liquid Cannabis fertilizers for the first 1-2 weeks, depending on the plant's size. Start feeding when you see the growth accelerate.

Frequently Asked Questions

Do I need to buffer this coco coir?

No, Pro-XL Organic Fertilized comes ready to use. It is already treated and buffered, so you can plant directly into it without the hassle of washing or buffering it yourself.

Can I use this for autoflowering seeds?

Absolutely. The airy structure of coco is perfect for autoflowers, allowing their roots to expand quickly before the flowering clock starts ticking. Just be mindful of the nutrients; the pre-fertilized load is gentle enough for most autos.

How long do the nutrients in the bag last?

The organic nutrients and humus provide food for the first stage of life. Typically, you should start your liquid feeding schedule after about 10 to 14 days, or when the plants show they are hungry.

Personal Experience of Pevgrow’s CEO (Alan)

I've always been a fan of coco for its speed, but mixing nutrients from day one can be a pain. What I love about this Pro-XL bag is the convenience. I used it recently for a batch of clones, and the difference in root whiteness and thickness was noticeable compared to inert coco.

The addition of humus is the game-changer here. It adds that biological buffer that pure coco often lacks. My trick? I mix in a little extra perlite if I'm growing in a humid environment to boost the drainage even more. It’s a solid, reliable choice that forgives small watering mistakes.
