Depends how much you're trying to grow. People come on this site and then get upset when no one answers their question, but they don't give all the info needed for someone to really answer your question. How big an area? What are you growing? How many plants? ETc. These are important before someone can answer your question. That is likely why no one bothers to answer your questions because too many newbies come in and ask random questions while giving no background info at all.
