Description
CANNA Terra Professional Soil 50 Litre is CANNA’s standard professional soil medium — a high-quality, ready-to-use growing substrate that provides an excellent foundation for intensive indoor plant cultivation. Terra Professional is formulated with the same careful attention to structural composition, pH stability, and nutrient profile that characterises CANNA’s approach to growing media development, delivering the consistent, reliable performance that growers relying on soil-based systems require across every growing cycle.
The CANNA Terra Professional Formulation
CANNA Terra Professional is built around a base of carefully selected peat and bark that provides the physical structure, moisture retention, and aeration profile optimal for intensively grown indoor plants. The formulation is pH-adjusted to the ideal range for soil-based growing, eliminating the starting pH correction that generic composts often require. A baseline nutrient charge provides fertility for the early stages of plant development — supporting rapid establishment without requiring external nutrient input for the first two to three weeks of the growing cycle. The medium is screened to remove coarse material that could create inconsistent drainage through the pot profile. Consistent particle size distribution ensures even moisture distribution and root penetration throughout the container, preventing the waterlogged lower zones and dry upper zones that improperly structured growing media can develop. CANNA Terra Professional is the step below their Professional Plus range — providing excellent performance for serious indoor growing at a more accessible price point. Many growers run Terra Professional through their vegetative phase and switch to Terra Professional Plus for their flowering containers where the premium performance of the Plus formulation adds the most value. At The Horticulture Company we stock both CANNA Terra ranges and can advise on which suits your specific growing system and budget.
Compatible Nutrients and Practical Use
Fill containers directly from the bag. Begin feeding with CANNA Terra Vega after the initial nutrient charge is exhausted. Transition to CANNA Terra Flores at the start of flowering. Compatible with CANNA’s complete additive range for a fully matched growing system.
