may wanna wait a bit longer than 3 hrs my friend
How bout all summer?

The
half-life of glyphosate in soil ranges between
2 and 197 days; a typical field half-life of 47 days has been suggested. Soil and climate conditions affect glyphosate's persistence in soil. The median half-life of glyphosate in water varies from a few to 91 days.
[7] At a site in Texas, half-life was as little as three days. A site in Iowa had a half-life of 141 days.
[44] The glyphosate metabolite AMPA has been found in Swedish forest soils up to two years after a glyphosate application. In this case, the persistence of AMPA was attributed to the soil being frozen for most of the year.
[45] Glyphosate adsorption to soil, and later release from soil, varies depending on the kind of soil.
[46][47] A 2009 study using a RoundUp formulation concluded absorption into plants delays subsequent soil degradation and can increase glyphosate persistence in soil from two to six times.

According to the
National Pesticide Information Center fact sheet, glyphosate is not included in compounds tested for by the Food and Drug Administration's Pesticide Residue Monitoring Program, nor in the United States Department of Agriculture's Pesticide Data Program. However, a field test showed that
lettuce,
carrots, and
barley contained glyphosate residues up to one year after the soil was treated with 3.71 lb of glyphosate per acre (4.15 kg per hectare
