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.

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.

I think this is a great organic fertilizer that can be used throughout your garden whether your plants are in the ground, potted, or indoors for seedlings or established plants. I highly recommend it. All of my plants love it and it is not harsh on any of them. Definitely follow the instructions on the bottle. The key for me is to not water the plants right before. If it is for potted plants and depending on the size I do little by little. Then after I finish I will go back to the first one to see if it needs more. You don't want the fertilizer draining out of the bottle - you want to make sure it all stays in the soil. This is fermented fish and seaweed so the concentrate in the bottle does have a punch as expected but once it is diluted there is barely any smell or any off putting smell. That is also why I do little by little so the fertilizer does not drain down into the drip trays. I can see it making the smell stronger as it evaporates.

Hanging baskets thriving. Planters love it. Shake well. Mix according to the label. Enjoy the results!

The smell of this fertilizer almost takes your breathe away upon opening the bottle. I was very worried about stinking up my house while watering my houseplants. The smell is much more bearable once mixed with water and I am happy to report that it leaves no lingering smell in my home. We have over 100 houseplants in our collection so I believe our house is a good test. My plants absolutely exploded after just one use. New leaves and vibrant leaf colour, even during our cold dreary Canadian winters. Will be buying again when needed but since it comes in such a large bottle and you use so little each time, I believe it will last a long time.
