Last year I bought the BMO Trio (Grow it green, foliar harmony, and flower power + free bottle of super plant tonic). I used a small amount of the nutrients for a grow that I ended up not continuing. I put the nutes in a box and they have been sitting on a shelf for nearly 9 months. When I put them away, I made sure the caps were loose, knowing the contents were live. Unfortunately, I found them today with the caps tight and the bottles had negative pressure inside (someone I live with moved them and discovered the loose caps, and tightened them). The batch date was 2-17-15 and the shelf life is 1.5 years, so I'm thinking they should be okay. But, the caps have been tight for months now, and clearly no oxygen got inside, so I fear that the live organisms are now dead. Opinions? Should I just buy a fresh batch since its only like $35 shipped?
