Best Stuff Ever!
I love this stuff! I have to get a bigger bag! It did wonders for everything I planted last season. I wish I could find it in a local store as I want a huge bag this year! My plants thrived with this. Germination was off the charts and growth was exponential. Everything was green and lush! I love this product!

Great for Transplanting Indoor Houseplants
Purchased this on the advice of one of my plant groups. It seems to assist in the shock of transplanting and helps the roots take to the new soil.

Fantastic for healthy and thriving plants
I’ve been using Big Foot Mycorrhizae for a while now, and the results have been amazing! My plants are growing faster, looking greener, and producing more flowers and veggies than before. The blend of biochar, kelp, humic acid, and castings really makes a difference. It’s easy to use—just mix it into the soil or sprinkle it around the roots. I love that it’s organic and OMRI-listed, which gives me confidence that I’m using a high-quality product. The 4 oz bag may seem small, but a little goes a long way, making it a great value for the price. Definitely worth trying if you want stronger, healthier plants!

If your looking for total dissolving in water product then..
First lm be clear and say that this product did perform excellent as it was designed to do and had noticeable great impact on the plants(vegs, flowers and fruit) that was absolutely satisfying especially in comparison without using it but I only have one issue: I use a 3 gallon heavy duty pump sprayer bc I have such a massive garden and greenhouse that’s at capacity so I have to feed my plants soil carefully and timely so with that being said when I add it to my water it dissolves almost immediately from looking at it but bc of the darker ingredients the water isn’t see through for long and the first time I got to bottom of use I noticed that it didn’t spray as strong as normally and thicker but there were pieces of the mycro still in the bottom that do t dissolve and the whole can did that so if I want to give a rating. It would be a 8 out of 10. ONLY bc I use it strictly with water feeding. Great on seedlings and that’s a 10/10. Effectiveness 10/10: great product and affordable!

This stuff is a game changer!
I used big foot on transferring clones to soil. Given the proper light and humidity the clones are looking healthy. It’s a bit pricey, but you don’t need much for good results. Another alternative is ( Mykos Xtreme Garening ) it’s cheaper, and you get a lot more. So ether way these are my go too.

Unbelievable growth
I had my doubts with this product, read all reviews and ordered. Used first on some tomato plants. Repotted a couple of weeks ago and the growth has been phenomenal, almost doubled in size. I’m also watering with some plant food but plant food alone was not as successful. Great value and new addition to gardening.

It works!!
Worked and worked WELL. First red sunflower plant I relocated and planted died almost instantly. Dang! 2nd transplant- I put in water for 10 days. It grew additional roots. Followed directions, l dig a hole, poured in a teaspoon and came back in the afternoon expecting a dead or dying plant. Nope! It was slightly droopy but by the next day; upright and perky!! Impressive.

I wish I could buy larger quantities here. They advertise it, but it seems only available in the USA. The combination of Mycorrhizae propagules with a small amount of Biochar, along with Worm Castings and Kelp/Humic Acid, is very effective! Un mélange parfait, qui fait effet ! J'apprécierais qu'ils nous offrent des options pour de plus gros volumes. Ce serait idéal! My Plants are addicted!

Bought the tiniest bag of these, and use them anytime I replant one of my indoor plants. As Tanner explained, there are good fungi (this) and bad fungi that will make home around your roots, so if you use this instead, it leaves no room for the bad fungi to move in and hurt the root system. It only takes a teaspoon for your little plants so even the tiny bag is going to last me awhile. It also contains worm castings which are a natural fertilizer for your plants. Nothing bad about this product! Will continue to be my go-to product from now on.

Works great.

I like this stuff over other mycco products, it's cheaper and doesnt seem to have as many nutrients in it as others so your plants don't get a shock of nutrients but they do get the mycco they need. I generally use this when transplanting, sewing seeds and an occasional topper to old soil.

If you're growing any plants (cannabis, vegetables, etc) in your garden, mycorizae is definitely a huge benefit. Just sprinkle a little when transplanting and you'll notice a huge difference. This is a great product!
