This stuff is pure gold. I have been gardening indoors and out for a few years now with my share of success and failure. I felt the need to share how worm castings and kelp have produced some great plants lately, like the ones that look like they are photo-shopped on the miracle grow bags. MG has it uses but the worm casting kelp mix has been doing wonders, I highly recommend it. It makes it easy to grow vigorous plants. I don't work for any company but I am a passionate knowledge whore who likes to share tips i have learned so far.
