Collection: Green House Mineral Line

The Bio Line works with organic raw materials and is designed for slow release in the substrate, while the Mineral Line is water-soluble and makes nutrients available more quickly. Green House Feeding positions the Mineral Line for soil, coco, and hydro, and the Bio Line primarily for soil, coco, and similar substrates.

For beginners, the Bio Line is usually much simpler because, according to the manufacturer, it is used as a top dressing or mixed into the substrate, and BioGrow/BioBloom each release nutrients for about 8 weeks. In practice, it is therefore often more forgiving, while the Mineral Line is controlled more precisely and, depending on the setup, may require EC and pH control.

For the Bio Line, BioGrow is intended for the vegetative phase, while with the Mineral Line, Grow takes over. BioGrow is described as an 8-week all-in-one mix for growth, while Mineral Grow is a mineral fertilizer specifically for the growth phase.

In the Bio Line, BioBloom is intended for flowering and fruiting. In the Mineral Line, the choice depends on the plant type and flowering time, such as shortFlowering, Hybrids, or Long Flowering.

According to the manufacturer, Hybrids was developed for medium-flowering varieties and is intended to provide nutrient ratios for typical hybrid genetics. The product catalog also mentions that the formula contains more magnesium and is specifically designed for hybrid strains with a flowering time of approximately 8–10 weeks.

Yes, Green House Feeding explicitly states that shortFlowering is suitable for short-flowering and autoflowering plants. This makes the question particularly relevant for searches, as many buyers are specifically looking for a fertilizer for autos.

The booster provides additional phosphorus, potassium, magnesium, and trace elements and is designed to support flower formation, flower density, and resin production. Green House Feeding describes it as a supplement to the basic fertilization within the Mineral Line.

CalMag is particularly useful when working with soft water, in hydro, via fertigation, or for quickly correcting a deficiency. According to the manufacturer, it is a water-soluble supplement with nitrogen, calcium, and magnesium that is quickly available.

The BioEnhancer is primarily intended to improve nutrient uptake, act as a soil conditioner, and, according to the manufacturer, can also be used for germination, cuttings, root development, and as a foliar spray. The official composition lists humic acids, seaweed extract, Trichoderma harzianum, and Bacillus subtilis.
