There are many ways to brew any particular green tea, we give conservative recommendations because many of our customers are first timers at brewing green tea and it is quite easy to over brew and become bitter. Generally speaking, if you brew at a lower temperature you can get away with brewing for a longer time or more leaf. It all depends on your preferences.

On some minuscule level, probably ALL green tea (and just about any other food or drink) has "some" level of chemical residue remaining in the product. In Japan, green teas must not exceed the same MRI (maximum residue levels) set by by government regulation regardless of whether they are organic or not. When pesticides are used, they are usually applied in the fall before any spring growth has begun and they are usually non-systemic type. Whether you get it from us or not, it is highly unlikely there is any remaining pesticides in non-organic Japanese green tea you are buying. Further, certified organic green teas must use organic fertilizer which takes longer to break down, the factory it is processed in must not process non-organic green teas, etc. There are many green tea producers growing organic-like green tea which cannot be labeled as such due to the strict requirements needed to apply the organic label to it. From a health benefit point of view, I cannot see, nor have I ever come across any study showing that an organic green tea would be any more healthy for you than a non-organic type or vice versa.
