SM- any preference on brands that worked better for coco app? Always used Age Old Kelp in my soil mixes, occasionally toss it in the coco mixes. Was looking at Super Nova as a kelp additive this run since i run the Dark Energy from em and love it.
So far I like every seaweed/kelp product I've tried as they help mostly with micronutrients and are a great source of what I call "soft" N. I have not (yet) used any seaweed or kelp product to the point of causing lockouts, but my tendency when using anything is to go much lighter than recommended. The other one I like to use a lot is the dry MaxiCrop, that I then mix into a liquid myself. I like it because I'm not paying to ship water. I've never had a chance to use Age Old, but would if I got some, same with any of them. I personally think that a variety isn't a bad thing here, so I often switch around the kelp products during the grow.
I have on hand the MaxiCrop, Eco-Nutrient, Growmore seaweed extract, and... a dry kelp, can't remember the brand. Wait, I might have two different kelps. The dry stuff smells like the sea.
