CANNA Terra Professional is a nitrogen-rich, pre-fertilised potting mix engineered for indoor cannabis and high-performance plant cultivation. It blends upgraded black peat, granulated peat moss, and perlite into a structure that drains well, holds moisture evenly, and gives roots the loose, aerated medium they need to establish fast. Unlike standard potting mixes from garden centres, Terra Professional is developed specifically for the feeding schedules and growth rates growers expect from a CANNA nutrient programme — arriving in a 50L bag ready to fill containers and get to work.
Specifications
- Allow 1–2 weeks after transplanting before introducing full-strength nutrients — the pre-fertiliser charge in Terra Professional gives young plants what they need in the early stages without risk of overfeeding.
- Water to runoff on each feed and monitor runoff EC to track salt accumulation — Terra Professional holds moisture well, which means salts can build up faster than expected if feeding is too frequent.
- For best structure and drainage in larger pots, lightly loosen the mix before filling — peat-based substrates can compact slightly in the bag during transport.

Frequently Asked Questions
How long does the pre-fertiliser charge last?
The starter nutrient charge in Terra Professional typically lasts 1–2 weeks from transplanting, depending on pot size and watering frequency. After this period, begin feeding with CANNA Terra Vega at the recommended rate on the CANNA feed chart.
Can I use Terra Professional with other nutrient brands?
Yes. Terra Professional is a substrate, not a nutrient system — it works with any soil-compatible nutrient programme. It is optimised for CANNA Terra nutrients but performs well with other brands designed for soil or peat-based mediums.
What pH should I target when feeding in Terra Professional?
Target a feed pH of 6.0–7.0 for soil-based growing. CANNA recommends 6.2–6.8 specifically for the Terra range. This range keeps the full spectrum of soil nutrients available to plant roots throughout the grow cycle.
Is Terra Professional reusable between grows?
Yes, with preparation. Used Terra Professional can be flushed, allowed to dry, and amended with fresh perlite and a small amount of new mix before reuse. The structure degrades with each cycle, and the pre-fertiliser charge is depleted — factor both into your approach for subsequent grows.
What is the difference between Terra Professional and Terra Professional Plus?
Terra Professional Plus contains a higher perlite ratio for improved drainage and aeration, making it better suited to growers who water frequently or run larger containers where compaction over time is a concern. Standard Terra Professional suits most indoor soil grows without modification.
