Really Good Stuff Increased my harvest for sure.

January 21, 2021

Can't Go Wrong trying this stuff it is cheap and affordable fast delivery all the time Have noticed my crops have been healthier and they taste better as well Loving the Humic acids It also gave me a surprise when i got spring tails in my soil for the first time Not only are springtails harmless to the garden & do not bite, but their presence indicates good soil health. Their diet consists of decaying matter, fungus, & bacteria, & their activity helps keep nitrogen in the soil.

Been Using this stuff for 3 harvests now and it is great definitely Recommend this product.

Worked on my lawn

August 13, 2021

My previous house owner neglected the lawn before selling the house. The soil was compacted and there were lots of weeds, patches and brown spots. I applied 5ml per litre per 1000 sq ft once in two weeks. My lawn has improved a lot since I started applying this product. Soil is no more compacted and the grass is really thick. Probably the best in the neighbourhood!

Full disclosure - I also changed the fertilizer from Scotts to Acti-sol (organic fertilizer) during the same period. This may have also contributed to the improved health of the lawn.
