Question 1

Bio Terra PLUS CANNA looks great on paper with its 100% natural and certified organic composition, but how long does the substrate actually retain its fertile properties without needing to add fertilizers? Is there any feedback on the durability of the soil over several growing cycles, particularly in indoor conditions?

Accepted Answer

Bio Terra PLUS from CANNA is a 100% natural and certified organic potting mix, ready to use with good aeration thanks to its rich composition of peat, bark, and coconut fiber. It contains nutrients to start the cultivation, but its fertility naturally diminishes over time.Indoors, to maintain optimal growth over several cycles, it is advisable to provide complementary fertilizers, as the substrate does not indefinitely retain its fertile properties without additional input. Feedback has been positive regarding the quality and yield, but does not specify an exact duration without fertilization.To maximize nutrition, you can combine Bio Terra PLUS with nutrient solutions suitable for organic cultivation.

Question 2

This Bio Terra PLUS soil contains peat, special coir, and bark; it is pre-fertilized and certified organic. To optimize indoor yield with this substrate, is it necessary to add additional organic amendments during the cultivation, or is the initial formulation really sufficient until harvest?

Accepted Answer

CANNA's Bio Terra PLUS soil is pre-fertilized with slow-release organic fertilizers, providing a balanced and suitable nutrient supply throughout the cultivation. Its composition, based on peat, coir, and bark, ensures excellent water retention and effective drainage, limiting nutrient loss.In most cases, this initial formulation is perfectly sufficient until harvest, without the need for additional amendments. However, depending on your specific conditions (lighting, temperature, plant variety), it may be useful to occasionally adjust nutrition or pH to optimize yield.In summary: Bio Terra PLUS is designed for autonomous nutrient management indoors, providing you with a solid and easy-to-manage foundation for your crops.

Question 3

Does the CANNA Bio Terra PLUS substrate maintain good aeration and water retention in a compact indoor space of less than 1m² without adding amendments?

Accepted Answer

The CANNA Bio Terra PLUS substrate ensures good aeration thanks to its long-fiber structure and incorporates COCO for balanced water retention. In a compact indoor space of less than 1m², it can very well maintain these qualities without additional amendments, provided that appropriate watering is respected and perhaps slightly aerating the substrate before use to avoid any compaction. This substrate offers an ideal base for healthy root development without excessive constraints.

Question 4

What is the recommended frequency for adding additional fertilizers when using the Bio Terra Plus CANNA pre-fertilized soil in organic indoor cultivation?

Accepted Answer

The Bio Terra Plus CANNA soil is pre-fertilized and ensures a gradual release of nutrients over 4 to 6 weeks. It is advised to wait about 7 days before adding additional fertilizer to avoid overloading the substrate. In practice, liquid organic fertilizer supplementation can begin around the 2nd or 3rd week of cultivation, applying it every two or three waterings, alternating with clear water to prevent salt accumulation. During the vegetative phase and stretch, opt for a suitable growth fertilizer, possibly combined with a half-dose flowering fertilizer, to precisely meet the needs of the plants.

Question 5

What is the ideal frequency of watering recommended with CANNA Bio Terra Plus to avoid overwatering and optimize root development in indoor cultivation?

Accepted Answer

The CANNA Bio Terra PLUS soil is designed to provide an excellent balance between water retention and drainage, ideal for indoor cultivation. The frequency of watering should be adjusted according to the growth of the plant and the size of the pot. It is recommended to water moderately as soon as the surface of the soil starts to dry, while ensuring that the substrate never becomes completely dry or waterlogged.This soil promotes good aeration and limits the risks of overwatering, allowing the roots to develop deeply and healthily. Maintaining a balanced watering helps optimize nutrient availability while avoiding issues related to excess water.

Question 6

Bio Terra Plus ideal for fertilization regimen after 4 weeks of indoor growth?

Accepted Answer

Bio Terra Plus is an organic pre-fertilized potting soil designed to gradually release its nutrients over approximately 4 to 6 weeks. After 4 weeks of indoor growth, it continues to nourish your plants in a balanced manner. In the majority of cases, this potting soil is sufficient without additional input. However, if you observe signs such as a slowdown in growth or slight yellowing, a gentle supplementary fertilization with a liquid organic fertilizer may be beneficial to support your plants. It is recommended to introduce this gradual fertilization around the 3rd or 4th week, alternating with watering using plain water to avoid salt accumulation. In summary: Bio Terra Plus is ideal for managing initial nutrition, but a slight supplement of organic fertilizer after 4 weeks can optimize your indoor crops according to their needs.

Question 7

What is the effective lifespan of Bio Terra Plus potting soil once opened to guarantee its biological properties without the risk of contamination?

Accepted Answer

The CANNA - Bio Terra PLUS potting soil retains its biological properties and structure for several months after opening, provided it is stored indoors in a cool, dry place, protected from light, and in a well-sealed bag. To ensure fertilization effectiveness, the gradual release of nutrients is optimal during the 4 to 6 weeks following opening. Beyond that, the structure remains healthy, but it will be necessary to provide supplemental fertilizers to effectively nourish the plants. In summary, to avoid any contamination and preserve the quality of the potting soil, ensure careful storage and prioritize use within 1 to 2 months after opening.

Question 8

What quantity of crops can be obtained with a 50-liter bag of CANNA Bio Terra Plus soil to optimize yield and whether additional fertilizer is needed or not?

Accepted Answer

A 50-liter bag of CANNA Bio Terra Plus allows you to cultivate approximately 2 to 5 plants indoors, depending on the size of the pots (generally 10 to 20 liters). This 100% organic soil promotes good root development and healthy growth, naturally optimizing yield.To maximize production, it is important to provide additional fertilizer after the first week of growth. Bio Terra Plus contains an initial nutrient-rich mix, but it does not cover all needs over a complete cycle. We recommend using an appropriate fertilizer, for example among those in the organic fertilizer range, to ensure a constant supply of essential macro- and micronutrients.

Question 9

Is CANNA Bio Terra Plus suitable for repotting adult plants in small volumes or is a different, more aerated and less fertilized substrate better?

Accepted Answer

CANNA Bio Terra PLUS is a 100% natural substrate, well-structured thanks to blonde peat, coco fiber, and antiseptic bark, providing good aeration. It is pre-fertilized with organic fertilizers that are released gradually, ensuring optimal nutrition for the plant. For repotting adult plants in small volumes, this substrate remains a good choice, but one must remain vigilant: the richness in nutrients can become too high in a small volume, especially for plants sensitive to excessive fertilization. In this case, it is recommended to opt for a more aerated substrate with less fertilizer, or to add draining elements like perlite or un-fertilized coco fiber to better adapt the environment. In summary: Bio Terra PLUS is quite suitable, but for adult plants in small pots requiring a very draining and less nourishing substrate, a lighter and more aerated mix will be preferable to preserve root health and avoid over-fertilization.

Question 10

Is it possible to remotely monitor the humidity and temperature of the Bio Terra Plus substrate to optimize the automatic management of irrigation and ventilation in indoor cultivation?

Accepted Answer

The CANNA Bio Terra Plus substrate does not have an integrated system for measuring humidity or temperature, but its very aerated and balanced structure allows for easy insertion of third-party sensors. Thus, you can perfectly monitor remotely these parameters with soil moisture and temperature probes connected to a home automation solution or a controller. These sensors transmit data in real-time, enabling you to automatically adjust irrigation and ventilation to ensure optimal conditions for your plants in indoor cultivation.This approach ensures precise and effective control while avoiding the risks of overwatering or water stress, fully exploiting the qualities of the Bio Terra Plus substrate.

Question 11

What is the optimal durability of CANNA Bio Terra Plus potting soil once opened to prevent degradation of its properties before use?

Accepted Answer

The CANNA Bio Terra PLUS potting soil maintains its properties optimally for several months once opened, provided it is stored indoors, protected from excessive moisture and contamination. This storage well protects the airy structure and nutritional qualities of the substrate.Before use, it is ideal to aerate it slightly to avoid any compaction. The gradual release of nutrients lasts 4 to 6 weeks once in cultivation, with the possibility of adding supplementary fertilizers from the 2nd week if necessary.In summary, careful indoor storage preserves the quality of the potting soil for several months after opening, thus ensuring a healthy and efficient base for your crops.

Question 12

What is the approximate duration of nutrition provided by CANNA Bio Terra Plus before additional organic fertilizer becomes necessary?

Accepted Answer

CANNA Bio Terra PLUS provides balanced nutrition thanks to its slow-release organic fertilizers for approximately 4 to 6 weeks after the start of the cultivation. It is advisable to wait for about 7 days after setup before beginning additional feeding. In practice, a supplement of liquid organic fertilizer can be introduced as early as the 2nd or 3rd week, alternating with clear water irrigation to avoid salt buildup, which helps maintain good root development and healthy plants throughout the cultivation.
