Plagron Promix is a mix of the very best, carefully selected types of peat. The addition of various types of fibre results in a lightness and oxygen level found only in Plagron quality substrates. No nutrients have been added to Promix, only Plagron worm castings. The worm castings stimulate the growth of soil organisms and activate the organic fertilizers which have to be added from the first day. This makes Promix the perfect potting soil to fertilize organically according to your own judgement and choices. The result is a 100% organic yield. Promix produces the highest yields when used with Plagron Alga Grow, Alga Bloom and the additives from Plagron.

Because no nutrients are added to Promix, it is suitable for the more experienced grower. You are directly in control of the fertilization. So start fertilizing from day one with our organic grow phase nutrient Alga Grow.
Promix has a low EC value since it is not pre-fertilized. This is ideal for young plants, because they will experience little stress. Your plant can root quickly and therefore has a healthy basis for stable growth.
Promix is organic and certified by Control Union. This means that this substrate is suitable for organic cultivation and is good for people, animals and the environment. Promix is not pre-fertilized, contains a high organic content and is rich in soil life thanks to the added worm humus. Add organic nutrients from day one to support this soil life and your plant will grow and bloom naturally. This will benefit the taste of the final product.
