Startrex contains a large number of soil bacteria that immediately work to improve the soil and ensure better uptake of organic fertilizers. Most potting soils are sterilised in order to kill weed seeds and germs. This also kills all the beneficial soil bacteria and fungi. The result is that the soil life potting soil takes a long time to become established. By mixing your potting soil with Startrex, you can ensure that your soil comes to life immediately, for your plant to take root more quickly.

The 3 most important components of Startrex are fulvic acids, hummus and silicon. Fulvic acid is natures major transporter. It enters plant cells bringing the nutrients to the cells.

Mix 2 table spoons (25 gr) with each 5 litre of potting soil or coco.
