I will be sitting for the exam on May 9th but I'd like to know a couple of things. I know Lesco sells 13-2-5, 25-2-5, 0-0-7, 5-10-31, 28-5-12 and many other granular products. Are these available in liquid form for better coverage? It may seem like a dumb question, but if you don't know you don't know and the study materials for the exam never mention it. I'm pretty sure ChemLawn uses all liquid products.
