Plagron Light Mix 50 L – Airy Substrate for Maximum Control

Plagron Light Mix 50 L is the professional substrate composed of the finest selection of peats and perlite, designed to offer you total control over your crop's nutrition from day one. If you are looking for a blank canvas to apply your own feeding chart without interference, this is the growing medium you need.

Why choose this substrate for your grow?

Have you ever suffered the frustration of seeing your seedlings or recently rooted cuttings burn because the soil was too "hot" or loaded with salts? It is a common mistake that can ruin weeks of work before you even start properly.

Starting with an overloaded substrate not only stresses the roots but also limits your ability to correct deficiencies or excesses, turning the crop into a guessing game that generates anxiety and poor results. You don't want to play Russian roulette with your genetics.

The solution is Plagron Light Mix. By containing only a minimum amount of mineral nutrients for the first week, it eliminates the risk of burns and allows you to be the one who decides exactly what, how much, and when your plants eat. It is the perfect foundation for a professional, error-free crop.

Features and Benefits (FAB)

• Contains Perlite: This volcanic glass improves the structure of the Soil For Cannabis, creating air pockets. Benefit: Your roots will grow faster and breathe better, resulting in a more vigorous plant.
• Low EC (0.7 - 1.1): A low level of electrical conductivity. Benefit: You have absolute freedom to apply Cannabis fertilizers from the beginning without fear of blocking the roots.
• Balanced pH (5.5 - 6.9): Adjusted acidity level. Benefit: Ensures that nutrients are available for absorption immediately, avoiding deficiencies.
• Selected Peats: A mix of black, white, and fibrous peat. Benefit: Provides optimal water retention, keeping the medium moist but not waterlogged.
• Pre-fertilized for 1 week: Contains just enough for the start. Benefit: Ideal for Cloning and germination, giving the plant a gentle start before you start the heavy feeding.

How to use Plagron Light Mix correctly

Using this substrate is very simple, but requires you to be active with fertilization:

1. Fill the pot: Do not compress the soil excessively; let the perlite do its job of aerating.
2. Watering: Before planting, moisten the substrate slightly.
3. First week: You do not need to add liquid fertilizers, just water (preferably with a root stimulator).
4. From the second week: Start applying your favorite fertilizers according to the manufacturer's chart, as the initial nutrients will have been consumed.

Frequently Asked Questions

Is it suitable for autoflowering plants?

Yes, absolutely. Autoflowering plants have sensitive roots and prefer a light substrate like this one to expand quickly without nutrient stress.

Do I need to check the pH if I use this soil?

Although Plagron Light Mix comes with a stable pH, it is always recommended to measure and adjust the pH of your nutrient solution (water + fertilizer) to ensure maximum absorption.

Can I mix it with other substrates?

Yes, many growers mix it with worm castings or bat guano if they want to enrich it naturally, although it works perfectly on its own if you use liquid fertilizers.

Personal Experience of Pevgrow’s CEO (Alan)

I have used Plagron Light Mix in countless crops, especially when testing new genetics or when I want to be very precise with mineral fertilization. What I like most is the peace of mind it gives me during the seedling phase; I know I'm not going to burn them.

My trick is to use it for transplants: when I move a plant from a small pot to the final one, Light Mix ensures that the roots expand into the new medium immediately because it is very fluffy. If you like to control every milliliter of fertilizer you give your plants, this is the best substrate you can buy.
