  • The BEST EVER Plant Firtilizer/root Tone
If you have never used this product get some now. I’ve been gardening for 50 years and was able to sprout and grow things without fail in my awful soil with this fertilizer. It is expensive but you don’t need much to make it grow well. I will use this over any thing else on the market. My vegetable plants were lush and full of fruit and my flowers bloomed all season. I’m not a master gardener so this is better for me than trying to decide what soil I should use. I used this product in a small one ounce amount for the first time last year as a gift from a friend. This year I’m going to be able to use it more often after I purchased it. I’m starting my spring starts next month and there is no way I could root clones without this fertilizer. Just light, water, and this product to sprout your seeds or starts. Great Product !!!! 5 stars forever. ... show more

  • It works... almost too well. hah
Great product. I am a long time user of granular mykos and decided to give this product a try. It is a significant step up in cost from the product I was using, but the results can not be denied. In fact, the results are so impressive that I would recommend being cautious with how much you use. I grow tomatoes (wink) organically in soil and I have never seen tomatoes grow faster with bigger radial leaves. Be careful using this into flower. Strongly recommend discontinuing use when you flip to flowering your (wink) tomatoes. I have not yet used it to grow lettuces, herbs, or other edibles, but I will be doing a side by side comparison in the next few months. The results I have seen others post have been incredible. In my opinion this is a must have product for organic growers. A little goes a very long way. Half a teaspoon per gallon is plenty. I will be purchasing more soon. The price tag was a bit of a deterrent, but after seeing the results I believe it is well worth it. I'm a little over half way through a 4oz container after several rounds in grow tents. Some buyers complain that they have received containers with compromised seals (this is an issue as the seals are affixed with very low grade adhesive) and have stated that the weight was off and that the product appeared to have been tampered with. The weight of the container I received was on point and the results can not be denied. Far more effective than other mycorrhizae products I have used. I recommend buying from a reputable seller and not trying to save a few bucks. Spend the money one time and be happy. Don't sell yourself short buying from sellers of ill repute. ... show more

  • The Best Mycorrhizae on the Market
I have used 5 different mycorrhizae products so far, most were Endo/Ecto mixes, a few had tricoderma added...most of those brands were good, or adequate. However, this Plant Success Great White mix was far and away the best of them all. Great White was the only Myco blend which produced prolific white, dense roots. Not only was the abundance and quality the best, but spread and depth was superior. In fact, I used it on an eaten and dying pumpkin patch to hopefully recover what was lost (eventually failing due to the severity of the damage). After clearing out the dead patch I turned the soil over and was shocked to see some of the root balls thriving and white, specifically growing new horizontal roots. At first I though spending over 30.00 for 4 dry oz. was a lot of money to invest for Mycorrhiza, now I see it as a necessity next spring. Until then I m going to buy me try other brands using Great White as the benchmark. However, when I am prepping for next growing season in March...this will be the first product I buy. Some info on Great White (through a customer's eyes): A. This is a granular product NOT a fine powder, best used in a sprinkling fashion. B. The 4oz. will go a long way if not over used since it is so effective. C. Best results were found to be - patting onto planted new container plants before going into a pot or the ground;Or sprinkling a pinchful into the planting hole at the bottom, filling hole with plant half-way then again sprinkling around the mid-layer, finally giving the plant a pinch at the base once filled, then watering with a garden hose sprayer gently as to not disturb the stratified myco layers. D. Mixing the granules into my pre-mixed recipe of potting and garden soil respectively in their own 5gal buckets E. Follow the solution guide on the label. They base the amount used on container size. I really like the application-specific information instead of basing it on large 50gal reservoirs, or acres. ... show more
