Big Yields, Beautiful Plants, Fair Price
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.

Love this stuff
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.

Smells TERRIBLE, but highly effective!
I got this to pretreat garlic before planting. Smelled so gross (like fish LOL duh). However, every single garlic bulb planted has sprouted. It surely did not disappoint me!

Perfect for Seedlings - BONUS: Deer Hate It!
My bottle came in a plastic bag, tightly closed, so I didn't have the spillage issues others have described. I also get this delivered in January or February where heat is not an issue. I grow my seeds in soil blocks which means I have no trays of standing water. As a result, I don't have the smell issues. Once my soil blocks wick up the liquid, things get neutralized or something like that. (My seedling mixture is coir and earthworm castings.) I fertilize seedlings once a week at half the rate recommended in the bottle. When it comes to the outdoor gardens, well, that's a whole 'nother story. I only feed my herb/vegetable gardens on Mondays when I know that no one is coming over for a barbecue that smells like a bad fish fry. If I can time this so that it rains that night, even better for me. If I have bad weather, I fertilize later in the week but no later than Thursday. That smell will linger for a day or two, especially in hot, humid weather. The benefit of the lingering is that the deer HATE this. Their sense of smell is 50 times stronger than ours so if I'm smelling this stuff for two days, I know they're smelling it too, for a lot longer. This is part of my KTDA (Keep The Deer Away) strategy, and even though I live in the middle of wildlife management where deer pressure is nuts, I never have a problem with deer in my two-acre, seven-garden property. (But I am disciplined and consistent with keeping up with the deer situation.) You do have to shake this bottle before every use and you have to do it vigorously. Mix only what you are going to use; once the solution is mixed with water, it begins to break down. Don't store it in your shed or garage where you'll experience extreme temperature swings. I've never had a problem with the stench sticking to plastics but I do soak my plastic sprayer bottle in a solution of borax and water once a week in a five-gallon pail and throw in all the other stuff that's gotten grungy during the week. It's not an inexpensive product but the yield you'll get from your vegetable garden will more than cover the cost. I grow flowers to benefit my vegetables and I do find that they are more fragrant than flowers that are fertilized with other products. Fragrance is critical in keeping deer away so this is important to me. I haven't seen a drop in beneficial insects or non-beneficials, for that matter, so the only beast that seems to be offended by the smell are the giant rats with hooves that would love to enter and make a buffet out of my place. But with confidence, use as directed, and if the smell is really too much to bear and deer are not a problem, feed the soil and skip the foliar feedings.

Good fertilizer
I’ve been gardening for one year now so I’m still green. First time using this fertilizer I’ve noticed a boost in growth since I’ve started. My tomatoes plants and peppers love this stuff. Will try again

It smells awful but it works. One bonus of the bad smell is it helps keep the deer away from the garden. My flowers were very happy this season.

My roses, herbs and all other perennials love this stuff! Everything is growing, so many new shoots and the blooms are beautiful! So far, so good…Wish the bottle was a little bigger though!

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.
