Excellent product for the green thumb.
Size: 1 Gallon
This is a must have if you are a plant lover or you grow citrus trees. It turns things green makes plants more attractive and helps those plants be tougher. The blooms are brighter and the fruit tastes better.

Works amazingly
Size: 1 Gallon
I was encouraged by the reviews I read before purchasing the product. I must note one of the advantages is its being a liquid already and mixing well for use in a sprayer. I found that it has no scent that I could tell. It works amazingly well. I had a rapid growth out of my plants in a week or less less after using it the first time. It does last a very long time because you only use about an ounce to the gallon. I want to say this is made the most significant improvement in my plants and garden vegetables that I have seen using any fertilizer. I love the fact that it won’t burn the plants and is a huge advantage over other fertilizers I’ve used on my plants. And not being a corrosive chemical that causes other problems on your equipment. All the way around this exceeded my expectations and will continue to use it extensively. Really just couldn’t be happier with the product. It’s getting to be winter here and I stop using it when the leaves turn gray brown or fell off. I’ll continue to use it on any of the plants that have green leaves and will likely do some experiments to show the difference of with and without, but it is noticeable. Cost wise very affordable, ease of use is great. Long lasting as the gallon goes along way. Delighted I found it. Will be buying more.

I ordered liquid seaweed but Amazon sent liquid kelp which is for hydro gardening. I used it anyway in my garden. The plants seem to like it.
