Organic Sea-K for Plants Seaweed and Kelp Fertilizer Supplement Concentrated Extract Powder Nutrient

Mixes well. Use it for young and old plants. It is doing the job plants are thriving, good color.

Bought this in June 2025 as an avid orchid collector. They say it takes a bit to truly observe the long term effects of proper fertilizing in your orchid collection which has been true in my experience. All I can say is, this is absolutely a staple in my orchid growing routine now. I use half a teaspoon per gallon because regular and lower dosage is better for orchids IMO. Anyway, the blooms I've had since I began using this a little under a year ago have been some of the strongest in my collection. Orchids that struggled to bloom again are spiking etc. Highly recc.

Worked great for getting my small tricho seedlings a boost. Using only have the dose this stuff can go along way.

I'll use nothing else my plants are thriving and I can soak succulents that have dried out. Quality product.

Having experience in the past with soluble kelp extracts, I know they are hydrophilic and will turn into a sticky rock, so I am not trusting the resealable plastic bags. I immediately transferred the powder into airtight glass jars. A very fine powder that dissolves in water quickly. Hoping for great results using it.

For whatever reason this prime order was sent out through the post office and they lost it. Amazon immediately refunded the money then I found the product locally in a garden center. It works absolutely fantastic. I grow indoor mini tomatoes and mini sweet peppers over the winter plus a multitude of various house plants the seedlings are some of the strongest I’ve had in a long time and the colors are coming back on my silver dollar jades, and other succulents

I have never seen worm castings in my soil. Been using this every 3 weeks, for 3 about three months and I am seeing worm castings. Alot of people don't like worm castings because they are not pretty, but I love them because it tells me my soil is rich with microbes and worms naturally aerate the soil. This product works very well, super highly concentrated that goes a long way!

One of the very few supplements I run in hydro. This stuff actually makes a difference.

Great product acts like an innoculent to boost growth and supply organic matter to plants, boosts production,love it every gardeners helper

Excellent quality

I grow Atlantic Giant pumpkins competitively and had my most successful season last year by using this product extensively. I use it as both a foliar feed and as a root drench. I found it to be an effective biostimulant that made the plants greener and grow more vigorously. Additionally, the high percentage of potassium contributed to enhanced fruit growth. This product will be a staple of my gardening program going forward.

Hard to be objective here as I probably need to wait all season. What I will say is, my plants are thriving after several have been potted on. Wear a mask when using though, the powder is superfine and is a bit of an irritant if inhaled. Does NOT block my superfine can rose.

I've been adding it for the last 5 weeks on this new grow and I'm very impressed with the results so far. I use appropriately .5 to 1gram per 2 litres. The plant is in the veg state and is growing healthy, full canopy of green leaves, producing lots of bud locations. I would definitely recommend this product for the vegetation stage which will lead to lots of bud sites.
