Rhizophagus Intraradices IMO is the best mycorrhizae fungi I have used. Mycorrhizae spreads out from the plant’s roots reaching farther into places plant roots cannot. Feeding the plant more efficiently. Having the ability to be much smaller in size, finding micronutrients and creating a bigger surface area for absorption.. Living symbiotically, the fungi feeds the plant and in turn, the plant feeds the fungi, making for a much larger,resilient and healthier plant.. Azospirillum brasilense IMO (my favourite is this and Rizophagus, they are the two heavy lifters) is an amazing bacteria that can facilitate the nitrogen from organics,amendments and even the atmosphere. This alone makes for a boost in growth rate.. That’s not its only use, it also stimulates the production of plant growth hormone, essentially kicking the plant into overdrive. This bacteria has had the largest impact on the growth rate and also the plants size structure and yield of my plants.. Pseudomonas monteilii IMO has great effects also, it can help phosphorus uptake/availability while sequestering heavy metals in the soil.. While producing indole acetic acid that effects the growth and developmental processes of the plant.. Bracillius amyloliquefaciens is a great addition because it produces a natural antibiotic for the plant and really protects the root system of the plant.. Bacillus Subtilis is a jack of all trades, it can enhance nitrogen fixation and can solubilize phosphorus in the soil .. Bacillus Subtilis also defends against pathogens causing disease. It makes the plant resistant to environmental stress.. In turn, elevating the plants productivity ..
