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.

Nitrogen-Rich Pre-Fertilised Mix Contains a starter nutrient charge that supports early growth from transplant — reducing the gap between planting and active feeding.
Upgraded Peat & Perlite Blend Black peat, granulated peat moss, and perlite combine to give excellent drainage, consistent moisture retention, and a loose root-friendly structure.
Optimised for CANNA Nutrients Developed to work alongside CANNA Terra Vega and Terra Flores — the medium's pH and buffering characteristics are calibrated to the CANNA soil programme.
Indoor & Outdoor Use Works as effectively in outdoor containers and raised beds as it does in grow tents — a versatile substrate for year-round cultivation.

Grower Tip
  • 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.

How to Use

1
Loosen the mix — Open the bag and gently loosen the substrate before filling containers. Peat-based mixes can compact in transit — aerating before use improves root penetration.
2
Fill your containers — Fill pots to within 3–5cm of the rim to allow space for watering without overflow. Do not compact the medium.
3
Pre-wet before transplanting — Lightly water the medium with pH-adjusted water (6.0–7.0) before transplanting to activate the substrate and remove dry pockets.
4
Transplant and water in — Place your seedling or clone, water in gently, and allow 1–2 weeks before introducing CANNA Terra Vega at full strength.
5
Feed and monitor — Begin CANNA Terra Vega at the recommended rate, watering to runoff and checking runoff EC regularly. Switch to Terra Flores at the flip to flowering.

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.

Wow. This book takes time to read!!
Format: Hardcover
Ordered The Unseen Realm (Expanded Edition) and it turned out to be one of the more thought-provoking reads I’ve come across on biblical theology. What stood out most is how much it stretched my thinking on the heavenly council. The way the author walks through Scripture and builds that framework forces you to slow down and reconsider passages you may have read many times without catching the broader context. It’s detailed, but not in a way that feels inaccessible. There’s a lot of depth here, especially if you’re willing to follow the argument and check the references. It doesn’t just make claims—it works through them. I didn’t agree with every conclusion, but that didn’t take away from the value. If anything, it pushed me to think more carefully and engage the material at a deeper level. Compared to other books in this space, this one stands out for how it ties together Old and New Testament themes in a more cohesive way. For the price, it’s a great value. There’s a lot of substance here, and it’s the kind of book you’ll likely revisit rather than read once and move on. If you’re interested in the supernatural framework of Scripture and are open to having your assumptions challenged, this is a strong read.

Eye-opening Exposition of the Bible
Format: Paperback
I have the paperback which is 387 pages, plus Acknowledgments and Index. The book is well-written. I am a Christian and have read the Bible many times. Dr. Heiser's exposition on portions of the Bible were not something I had encountered before. I'll let Dr. Heiser speak for himself: "My goal is simple. When you open your Bible, I want you to be able to see it like ancient Israelites or first-century Jews saw it, to perceive and consider it as they would have. I want their supernatural worldview in your head." Pg. 13. Genesis 6:1-5, Psalm 82, Deuteronomy 32 and other Biblical passages, including New Testament passages reflect a worldview that at least to me was unfamiliar. His approach to exegesis of the Bible seems orthodox to me. Once again, I'll let Dr. Heiser speak for himself: "I still believe in the uniqueness of the God of the Bible. I still embrace the deity of Christ." Pg. 13. Nevertheless, looking at the Bible through this worldview is, for me, deeply affecting and not in a negative way. The existence of a heavenly host, not all of which honor God, God's desire for an Eden even after the failure of the first Eden, and three rebellions, not just one, all based on divine Scripture, were deeply educational and enlightening to me. The author argues for his points carefully and cites numerous scholarly treatises to support his arguments. The book also makes connections within the Bible to connect various passages, which a first-century Jew or Christian, assuming some literacy, would have recognized that a 21st century Christian, such as me, completely misses. The cosmic geography idea is not something I have encountered before. The book also provides background on the interpretation of Hebrew words and the author is careful to focus the range of acceptable interpretations. Elohim, in particular, gets careful exposition. If the topic interests you, I recommend the book highly. If you'd like to try out the late Dr. Heiser's thoughts first, he has a number of YouTube videos running from 15 minutes to 1+hour in length for you to watch.

Great Depth, Beautiful Edition.
Format: Hardcover
The deluxe hardcover is gorgeous, with art on the inside of the cover and diagrams and footnotes galore. I will say the footnotes get pretty deep, almost as many of them as there is "normal" text. But very, very well done deluxe anniversary edition. The content blows me away, and like Heiser says, I'll never read my Bible the same way again. Wouldn't recommend this book to most people, as sometimes I had to go back and re-read a passage, or got done with a footnote that was several paragraphs long and had to remember what the text was talking about before I got sidetracked by the footnote. But very glad I read it, very glad I own it. Also comes with a free digital download (though locked to their free app, Logos).

The best book so far from Dr. Michael Heiser!! A MUST-HAVE!!
Format: Paperback
This book is a must have! Dr. Michael Heiser was a great scholar that gave truth to all he taught. His book is really filled with good in depth information where you get more understanding with what you read from Scripture. It gives great detail explanation of many topics and references to where you can look into Scripture. There's many footnotes in it as well from him. He has many different books written and I think this is his best. So YES this is a must have and you should get "The Unseen Realm" from Dr. Michael Heiser.

Outstanding Book, Read Best with Careful Right Division
Format: Hardcover
Verified Purchase. I bought this book for myself and, after reading it, also purchased copies for several family members and friends. The Unseen Realm is one of the most thought-provoking and eye-opening biblical studies I’ve encountered. Michael Heiser does an excellent job restoring the supernatural worldview of Scripture and shedding light on passages that are often overlooked or misunderstood. From an Acts 9 Mid-Acts Dispensational perspective, however, the book is best read with discernment. The narrative frequently treats Acts 2 (Pentecost) as a major turning point in God’s program for the nations. Mid-Acts theology understands Acts 2 as still part of Israel’s prophetic kingdom program, with the distinct revelation of the Church, the Body of Christ, revealed later through the apostle Paul. In addition, the book’s strong emphasis on a unified, canon-wide storyline can blur the important Prophecy vs. Mystery distinction, particularly the uniquely Pauline revelation of the unprophesied mystery of the Body of Christ. Finally, while not teaching baptismal regeneration, the book affirms water baptism as meaningful for believers today, which differs from the Mid-Acts conviction that the Church participates only in the one baptism of the Spirit (1 Cor. 12:13). Overall, this is an excellent and enriching book that I gladly recommend — provided it is read with careful right division and Pauline distinctives firmly in place.
