Review: My tomatoes and herbs love it. So do my houseplants. I love it for two reasons: One, it helps me get big vegetable yields and grow beautiful plants. Two, it's all natural. As for the price, it's fair. Not the cheapest fertilizer on the market, but it's worth every penny.

*by J***. on 5 July 2025*

If I could give this 10 stars I would! Garden is sprung to life, everything is dark green and vibrant. I give half the dose of what is required and I am still impressed with the results. I've uses countless high end fertilizers, but this one is the real deal. I am growing everything from cannabis, squash, beans, greens and flowers, etc.
