    Top Mix is a high quality potting soil which has been fertilized by Mills. Once spread over the garden, it needs no looking after. Apart from black and white peat, Top Mix also consists of perlite. This volcanic rock substance has the ability to absorb large amounts of water and oxygen. It will gradually distribute these elements and, by doing so, enrich the soil. Top Mix makes sure the crop will have all it needs at its disposal.Top Mix is suitable for both short- and long-term cultivation and is available in a 50 litre package.Supplier source: https://erithhorticulture.com/product/top-mix-50l-70-per-pallet/

    TriPart® MicroAvailable in Hard or Soft water composition, TriPart® Micro is the foundation of the “building- block” system, providing micro and sub-micro nutrients and some complementary macro-nutrients. Use TriPart® Micro as directed all the way through growth and bloom.3-part “Building Block” nutrient system: T.A. TriPart® gives the best possible balance between concentration and flexibility.Why buy grow nutrients, bloom nutrients, a CalMag and a PK, when you can grow from start to finish with just three bottles!TriPart® nutrients allow you to perfectly match the changing needs of your plants by varying the mix as your grow progresses: more TriPart® Grow during growth, and more TriPart® Bloom for flowering and fruiting: simple and incredibly effective by design.Used by the most prestigious research laboratories and universities, including NASA, the TriPart® is an evolving system that we constantly update in line with the latest scientific discoveries, and improve through exhaustive testing in-house and with our partners in professional horticulture (see more on our pedigree in real-world food production and research here)Many nutrients claim  to  include  everything  that  your plant needs for healthy growth, but unlike most competitors, the TriPart® includes not just the primary and secondary nutrients necessary for basic plant nutrition, but a full range of micro and sub- micronutrients as well – and we chelate every possible element for enhanced uptake and stability. This is why the TriPart® delivers such impressive and reliable results in specialist markets where enhanced flavour, aroma, potency, and essential oil production are vital.The TriPart® is available with hard or soft water formulations of TriPart® Micro to ensure that calcium levels in your nutrient solution remain optimal preventing the lockout / deficiency problems that universal nutrients can provoke.Supplier source: https://erithhorticulture.com/product/tripart-micro-hard-10l-aka-flora-micro/
