Best fertilizer out there
Great product. In fact I went to another brand to โsave moneyโ and Iโm not impressed with it. Will be switching back to Neptunes Harvest once the other is done. It makes my plants thrive!! Great consistency and thickness. It does smell gross but what do you expect lol.

My Magical Neptune Elixir
I use this on my garden one week out of the month, with regular fertilizer two weeks of the month, and also regular bone meal. I did notice that when I use this kelp stuff, it seems to generate new roots from the base of the plant, get stronger, and producing more fruits and veggies! These things are most likely to happen during/after kelp week.This stuff goes a long way for a small bottle. It dissolves perfectly, and there is a very faint ocean smell to the water when it is mixed in. Nothing terrible smelling.Weโve been using this product for years in our garden, and it truly gives an extra boost to any plants. Our garden truly thrives, and produces so many fruits and vegetables. We use it on almost everything: our flowers, strawberries, blueberries, melons, tomatoes, lettuce, garlic, cucumbers, onions, peppers, carrots, squash plants and more!Fish and Seaweed are known to build the natural sugar in plants. Flowers and foliage will be stronger and more colorful. Adding this to your garden will give you better vegetables/fruit yields. This is a great fertilizer for a few key reasons: The first is that it's a great source of Phosphorus which is used by new plants to produce strong roots and so is great for any root vegetables! This is a secret ingredient that all gardeners use to improve their garden! I highly recommend using for your plants!

Great fertilizer - fishy smell
This is a great fertilizer. Some people donโt like to use this inside because of the slight fishy smell. As for me, It is worth it.

Works well but itโs very concentrated
Neptune has always been my go-to fertilizer but you have to hold your breath when mixing it and be very careful with the dilution ratio. This is the 1st time I have ever used it for seedlings. Instead of 1 tsp per cup of water, I used a half tsp and it still burned my tomatoes (at 6 inches tall, they were more mature than seedlings), and caused purple leaves overnight. Also, my bottle was so poorly packaged, it leaked all over the plastic bag it was wrapped in. Itโs great stuff, just be careful with it.

Stinks, but my plants love it!
I have to admit, this stuff smells pretty strong โ definitely not something you want to sniff too closely. That said, Iโve been using it on my indoor plants and they are thriving! Leaves are greener, plants are bushier, and they just look so much healthier since I started using it.If you can handle the smell, itโs totally worth it. My plants are loving it, and thatโs all that really matters!

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.

Works great
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.
