It's formulated specifically for indoor grow-room conditions (though it performs outdoors too) and is built to work hand-in-glove with the Terra nutrient line: the mix carries a mineral starter charge with its ratios matched to Canna Terra feeds, so your plants transition seamlessly onto the schedule.\u003c\/p\u003e\n\u003cp\u003eThe blend is airy white peat moss with graded tree bark. The bark isn't filler — it has a natural antiseptic action in the root zone and does the aeration job perlite does in ordinary mixes, promoting exceptional root development and noticeably thicker stems. The medium is pH-adjusted with a lime charge sized to hold stable for an entire growing cycle, and it carries trace elements and chelates that protect plants through growth.\u003c\/p\u003e\n\n\u003ch3\u003eGenuine UK Stock\u003c\/h3\u003e\n\u003cp\u003eWe only sell genuine UK-market Canna, supplied through Canna's official UK distribution — current UK bags, fresh stock rotation, dispatched fast from our UK warehouse.\u003c\/p\u003e\n\n\u003ch3\u003eProfessional Plus vs Terra Professional — which one is this?\u003c\/h3\u003e\n\u003cp\u003eCanna makes two main Terra mixes and the names cause endless confusion, so here's the actual difference. \u003cstrong\u003eTerra Professional\u003c\/strong\u003e (the standard mix) is nitrogen-rich and blends upgraded black peat, granulated peat moss and perlite. \u003cstrong\u003eTerra Professional Plus\u003c\/strong\u003e — this product — is the premium tier: the purest raw materials Canna uses, built on top-quality white peat with antiseptic tree bark taking the place of perlite.
