Which kelp extract is best and what strength is best when watering plants with a very quick thirst.?
You're looking for extract of North Atlantic kelp or Norwegian kelp, Ascophyllum nodosum.
It should be hydrolised or cold pressed, not alkaloid extraction as that can mess with its microbial makeup.
It should be a very fine powder and black as ink.
NPK is 0-0-14.
Buy it cheap by the lb at customhydronutrients.com
That's what I am trying to learn.... saving money on a better product.I make up a stock solution from dry kelp extract every week and it's very messy. Just seems to want to get everywhere, it also clumps together but eventually completely soluble.
Any time you see these thick dark syrupy concoctions from expensive nute companies you can bet a key ingredient is kelp.
Cut them out and make it yourself.
