Plagron Allmix produces the highest yields when used with Plagron Alga Grow, Alga Bloom and the additives from Plagron.

Plagron Allmix contains sufficient organic nutrients for the first six weeks of your cultivation. Because Allmix is richly fertilized, it is not suitable for very young plants. Wait one to two weeks before you put your plant in Allmix, or flush the Allmix before use. After this, you can start growing immediately without having to worry about whether your plant is getting enough of the right nutrients. We advise to start fertilizing from week 4, because it takes about two weeks for organic nutrients to be absorbed by the plant.

Because of the addition of unique worm humus, Plagron Allmix contains a high organic content and a rich soil life. This ensures vigorous growth. In addition, Allmix has a finer fibre structure. This ensures better water retention.

Plagron Allmix is organic and certified by Control Union. This means that this base nutrient is suitable for organic cultivation and is good for people, animals and the environment. Plagron Allmix contains a rich soil life because of the added worm humus, and organic fertilizers which support this soil life. This means your plant grows and flowers in a natural way. This benefits the taste of the final product.

Yes, you can use Supermix to upgrade your peat substrates. Unused, these substrates are prefertilized. This means you don't need to use Supermix for your first grow on any of these substrates.

No, combined with our 100% NATURAL Grow Style you don't have to regulate the pH and EC value of nutrient solutions.

When you need to start giving nutrients depends on conditions such as the amount of light per square meter, the type of plant and other factors. It takes about two weeks for organic nutrients to become available to the plant. If you start fertilising from the fourth week, the nutrients will be available in week six, right at the point were the pre-fertilisation of the Plagron Allmix runs out. Check the grow schedule to find out if you need Alga Grow or Alga Bloom and in what dosage.

Plagron Allmix is fully fertilized. Young plants that are not yet accustomed to high EC-values may struggle when they are suddenly planted into a maximally fertilized soil. Therefore we recommend that you flush the Plagron Allmix before putting the plant into the Plagron Allmix. This is done by filling the pot (eg 10 liters) with Plagron Allmix and rinsing it with 5 to 10 liters of water. After this, the plant can be planted directly. The directly available nutrients will be flushed out with the water. Within the following days, the EC value in Plagron Allmix will rise again and gradually the non absorbable fertilizers will be released.
