Frequently asked questions

• What is Atami's Bi Grow Mix?

  It's a 100% organic professional substrate with a medium dose of fertilisers already built in, and free of pathogens and fungi. It's formulated with organic matter, sphagnum peat, coco coir and lime. Its coco coir guarantees optimal aeration and extensive, strong root development.

• How long can I grow without fertilising?

  The built-in nutrients let you grow for the first 3 weeks without applying any additional fertiliser. During that period, watering with plain water is enough. From the fourth week onwards, you start adding liquid nutrients.

• What pH and EC does it have from the start?

  It comes with pH 6 and EC 1.3, ready to use from day one. You don't need to correct or prepare the substrate before planting. That saves you time and reduces the risk of mistakes when starting your grow.

• How do you use it step by step?

  Apply it directly to the pot or the growing bed, with no previous mixing. Water with plain water only for the first three weeks and, from the fourth week, introduce liquid nutrients at mild doses. Gradually increase the dose according to how the plant responds.

• What fertilisers should I combine it with to get the most out of it?

  It's recommended to combine it with Atami's organic fertilisers to boost results in the later stages. Being an organic substrate, it naturally fits with fertiliser lines of the same type. Always start with mild doses and increase them gradually.

• Is it safe for organic growing?

  Yes, it's a 100% organic substrate and free of harmful pathogens and fungi. Its base of organic matter, sphagnum peat and lime is high quality. It's a very safe choice if you're after an organic grow from start to finish.
