I've had a 1 liter each of Botanicare Grow and Bloom for more than a year and I still have 1/2 of the Grow and 1/4 of the Bloom. I use a few other products to enhance the beneficial soil fungi and bacteria and I've pissed around with free Bloombastic samples, though I'm not convinced that molasses isn't just as good. Check your reps Farmer Rich. I think PR is trying to get in touch.
