Amazing stuff.
I have to do this review in conjunction with another product from this company as I used both at the same time so can not say if the results I have had are down to one or both of these products but I believe it is the combination of the two as diversity is key in organic growing. The other product I used is their Mychor plus. (Wish I knew how to attach a link!) I do a lot of no till, organic, living soil growing indoors and have been doing so successfully for about 4 years now, I discovered the 'perfect' living soil recipe about 2 years ago and have had great success with it but, (and this is where this product shines) usually once a new bed has been mixed and set I have to wait 10-14 days for the mycorrhizae and microbiology to become active enough to plant in it. I always sow a 12 seed cover crop as soon as it is mixed as this helps in many ways and up to now the cover crop growth has been slow and sometimes erratic as the soil just is not ready yet. I started a new bed recently using all my original ingredients, peat, worm casts, rock dust, malted barley, gypsum etc etc but also these two myco and bacteria blends from TNC and as usual sowed my usual cover crop mix. I did a compost tea which I do monthly anyway but added 2 teaspoons of this product and I always use it within 36 hours, ideally at 24 hours and this brew had a nice thick brown foam partly from soap nut but as its never looked quite like this before it is down to good bacterial growth. 3 days after watering in some of the cover crop (vetch & barley among others) is 8 inches tall, I have never seen growth like it including the many other far better growers than me that I watch on Youtube, absolutely amazing results and it can only be down to these blends from TNC.in This bacteria has kick started my soil mix in conjunction with their myco incredibly fast, no waiting 2 weeks before planting anymore. These 2 products have been the single biggest beneficial boost I have ever used so to say I am a fan is an understatement. One thing that really annoys me though is that over the last few years I have searched Amazon many times using keywords such as mycorrhizae beneficial bacteria and soil microbes and yet I have never found these products and only found them by chance when looking for bokashi bran! I really can not recommend these two products highly enough for organic gardening but particularly the no till method as we do not want to disturb the myco. i should point out that I already use several well known brands of myco but none have had an effect like these. I shall be using these products now in every cycle without fail. Thank you TNC.

Excellent value for money compost tea
If you can't be bothered to create your own, or buy other expensive instant compost teas - here's your best option. I use around 0.5-1G per liter once-or-twice a fortnight (whenever I top dress) alongside a Humic & Fulvic, or liquid seaweed feed. The results are amazing, my lettuce and chili's are loving it, and it's incredibly affordable. A must for any living soil grower.

It works
My Hydro setup (3D printer PETG tower) was gunking up really quickly with brown slime until I put this in the water. The bucket is now clean, and doesn't even need scrubbing between water fills. The rest is all fine and the plant roots are a nice healthy colour again. Recommended!

Extraordinary for root growth
I first used this on my tomatillos last spring, and the growth was obscene. The roots colonised the tray under the modules and adventitious roots covered the stems. Plants grew faster than I could transplant them and were absolutely huge. Good stuff, goes a long way.

Good so far
It’s hard to gauge microbial efficacy, but I used as directed and it hasn’t damaged any living plants which is a plus. I think the microbes are getting to work on some of the dead root material in the soil. There’s also plenty in the pack!

Seems like good stuff
I havent had any issues with the product, its easy to dissolve , there is something in it which seems a bit harder to break down but i just pour it all regardless. The plants are all doing well so i cant complain overall im happy , the price is decent and you dont need to buy huge amounts of it like other companies meaning u dont need to fork out 50-60e but instead can buy it as you need for 10e :) A+

il prodotto seppur fine polvere, una volta a contatto con l acqua crea dei sedimenti spessi, che a lungo andare tendono a tappare i filtri degli impianti idro.per un utilizzo safe, senza ostacoli, basta introdurre, per prima cosa, il prodotto in una sacca filtrante per compost tea e solo dopo introdurla nell impianto per almeno 48 ore.i risultati sono eclatanti.merita quel minimo d accorgimenti.

L applicazione del prodotto può venire al reinvaso o al primo trapianto semplicemente applicandone un cicchiaiono sotto le redaci. Oppure se la pianta è gia invasata si praticano dei semplici firellini vicino le redaci e si mette un cucchiaino del prodotto in essi, per poi richiuderli e annaffiare. Può alternativamemte essere applicato sciogliendolo in acqua (1gr per litro) ed innaffiando. Avevo un piccolo limone in vaso. Gli hanno ridato praticamente vita nel giro di un mese. La pianta è ora rigogliosa, forte e molto più resistente agli attacchi patogeni.
