Going to the farm supply today. They have 50 lb sacks and see if I can sigh the papers and get a couple of sacks. They want 28.00 for a 50 lb sack at the local hardware..........that is a lot. Same price for sulfate..................might as well do the paper signing and get some nitrate before they make us give a pint of blood and some dna to get on the list to get some..................I might look into finding a high urea content sub that will work. Bat Guano....? Im Looking though for someting that is cheaper than the nitrate..............cause Im thrifty not cheap....
