Good Stuff
I've been using the Bigfoot brand for about 2 years now and it has always performed very well for me. I use it for both indoors and outside in my vegetable garden.

Works great
Use this product when repotting my plants. They don’t suffer the stress and lag in growth after repotting.

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!

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!

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!

Works great! check price.
This stuff works great, however, be sure to check the price per weight. I was able to find this at my local greenhouse for much cheaper.

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.

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!

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.

I used this product for my tomato seedlings and they grew like weeds, very sturdy stems and a good height for being a month old. This is the first time I am growing tomatoes indoors, so I am very happy!
