Hi all, I'm wondering if anyone has tried making their own seaweed extract. I live across the street from the beach in a very pristine area of Alaska with several types of seaweed growing on the rocks aty low tide, so I have been collecting them and making a "smoothie" in the blender, adding some water and molasses and letting it sit for a few days, then pouring off the liquid from the sediment. It seems to work really well but I'm wondering how much I can use without giving too much nitrogen to my flowering plants. The ppm of the extract undiluted is only around 650 and the Ph is 6.1-6.2. Thanks....
The seaweed is a great tonic for the soil. What you are doing is is good. Just remember a little goes a long way. It is providing more micro nutrients more than anything, high in potassium and strangely ! Calcium Sent from my iPhone using Grasscity Forum
I'm growing in coco, so no there's soil, but the micros can't hurt either way. This stuff really seems to perk up my plants that's for sure. If I didn't already have a million other things to do I'd put it in bottles and sell it. Maybe some day I will.
