You should grow 100% NATURAL when you prefer a healthy end-product with the best smell and taste. All 100% NATURAL substrates and fertilisers are 100% organic and suitable for organic farming (CU certified). The basic plant nutrients Alga Grow and Alga Bloom are both 100% NATURAL products. These are fertilisers based on algae. They provide a respectively healthy growth and flowering of the plant.
When you choose 100% NATURAL products, you’re growing organically and it’s no longer necessary to measure the pH and EC value. An EC- meter can’t measure all organic nutrients. The biological life in the soil of the 100% NATURAL grow style will ensure that the nutrients remain available for your plants and will help to stabilise the pH value. That’s why you don’t have to measure pH values.
