Looks like some awesome stuff, I’ve got some of the water soluble kelp from kelp4less.com and I just sprouted a bunch of veggie seedlings in like a day using some of the kelp juice to water and mist them. My houseplants like this big elephant ear philodendron I have seem to love it too.
Looks like it’s a mild fertilizer and also stimulates hormonal activity in plants and has numerous uses… looks like a good foliar spray or watering about once a month would be great, maybe once a week.
The kind I have is little black chunks similar to charcoal that dissolve into a brown liquid when added to the water. At 1/4 teaspoon a gallon a 1/2 lb of it should go a long ways. If you live by the coast I would collect a bucket full of it and then add some water and cover it and let it rot, then dilute that mixture down and give it to your plants.
