🌿 Comparative test of mycorrhizae on Habanero peppers: Great White, DYNOMYCO, Mycotrex, and homemade mix

🌿 Comparative test of mycorrhizae on Habanero peppers: Great White, DYNOMYCO, Mycotrex, and homemade mix

👋 Hi Growers!

Today, we are sharing a homemade test we set up to explore the effects of different mycorrhizae on Habanero pepper plants. The idea of this comparison is simple: to observe, document, and compare how these fungal inoculants influence the growth, vigor, and resistance of the plants in a controlled but slightly stressful environment. Everything was done in indoor cultivation with identical conditions for each plant to ensure minimal bias.

Mycorrhizae are known to improve nutrient uptake, stimulate root growth, enhance stress tolerance, and optimize yields. But how do they actually perform in real situations, with nutrient and nutrient-free soil? That's what we wanted to find out!

🌟 Tested products

For this test, four treatments were applied to four Habanero chili plants:

• ✅ Great White Mycorrhizae

  

• ✅ DYNOMYCO

  

• ✅ Mycotrex (Biotabs)

  

• ✅ A mix combining the three products

  

📊 Purpose of the test

Compare the effectiveness of these mycorrhizae according to several criteria:

• Growth rate

• Size, color, and density of the foliage

• Resistance to water and heat stress

• Reaction to external aggressions (insects, diseases, etc.)

• Overall vigor of the plants

🌱 Equipment and growing conditions

• Cultivated species: Habanero pepper (Capsicum chinense)

• Number of pots: 4 (one per treatment)

• Volume of the jars: 7 liters each

• Substrate used: Plagron Promix potting soil, an organic substrate without added nutrients

Initial amendments (before transplanting)

Before transplanting the seedlings, the substrate was enriched with:

• 4 ml/L of Plagron Terra Grow (organic nutrient based on seaweed)

• 1.5 ml/L of Ancient Earth from Advanced Nutrients (improves soil structure, stimulates microbial life, reduces watering needs)

• 1 ml/L of BAC Calmag V2 (calcium and magnesium)

🌦️ Growing environment

• Culture room : Guerilla Box 120x60x180 cm

• Lighting : Agrolight LED 150W set to 25% via the dimmer

• Temperatures :

  • Day: between 24.5 °C and 26 °C

  • Night: 20 - 21 °C

• Relative humidity: not intentionally controlled to impose moderate stress

• Initial thermal stress: during the first 4 days after transplanting, the seedlings were placed outside, exposed to cool temperatures day and night to test their recovery ability

💧 Watering & nutrition

🔸 First watering (Week 1)

• Plagron Alga Bloom : 4 ml/L

• Ancient Earth: 1.5 ml/L

• BAC Calmag V2: 1 ml/L

🔸 Second watering (Week 2)

Dosages have been reduced by 25% to avoid any excess:

• Plagron Alga Bloom : 3 ml/L

• Ancient Earth: 1,125 ml/L

• BAC Calmag V2: 0.75 ml/L

• ➕ Addition of BAC Silica Power (silicon) at 0.5 ml/L to strengthen cell walls

📸 Visual Observation – Week 2

🌱 Results observed in the second week

🔹 Great White Mycorrhizae

• Visible rapid growth

• Medium-sized foliage, healthy coloration

• Some leaves have been nibbled (probably by an animal or insect), but the plant has recovered well

🔹 DYNOMYCO

• More compact plant

• Widest leaves of the group, quite thick

• Good overall vigor and uniform coloration

🔹 Mycotrex (Biotabs)

• Healthy plant but clearly smaller than the others

• Foliage correct but slower growth

🔹 Mix (Great White + DYNOMYCO + Mycotrex)

• Very balanced plant

• Second place for leaf width

• Good leaf density and robust appearance

🧠 First lessons

The results of this first phase show that:

• Great White allows for a quick recovery even after initial stress

• DYNOMYCO stands out for exceptional foliar development

• The house blend seems to combine the strengths of each product

• Mycotrex, although currently in decline, could prove useful in the long term

🔮 Program continuation

The test will continue for several more weeks with regular monitoring. The next observations will focus on:

• The evolution of aboveground biomass

• The appearance of the first flowers and the formation of fruits

• The condition of the root system at the time of repotting or at harvest

• The quality and the final yield

See you very soon for the continuation of this 100% field mycorrhizal comparison!
