I noticed signs for an organic fertilizer outside a garden section of a store today. The fertilizer is made from worm castings and bat guano.
Here is the funny part.
A man saw me looking at the fertilizer bags and told me it was a great fertilizer for growing WEED. :o
Pretty much depends on how you grow your WEED.
Putting that fertilizer in a hydroponic system might stink up the whole house. ;D
