I have some Espoma Kelp Meal and I want to use it on my plants. I found this article from Buildasoil that shows how to rehydrate the kelp meal to be used on the soil: https://buildasoil.com/blogs/news/11759569-diy-instant-kelp-meal-tea-coots-hydrated-kelp-meal-trick .
I’m going to start giving this to the seedlings once a day. I’ve been watering them with nutrients twice a day but I also want to give them some organic nutrients as well and kelp is supposed to be great for the plants.
I also have some powdered bat guano that I will start to incorporate into their feedings once they go into flower.
