Epoxy resins are low molecular weight pre-polymers or higher molecular weight polymers which normally contain at least two epoxide groups. The epoxide group is also sometimes referred to as a glycidyl or oxirane group.
Different grape varieties thrive in different climates, but typically do best in U.S. Department of Agriculture plant hardiness zones 5 through 9. Although highly perishable, when stored correctly, grapes can last up to six weeks after harvesting.
Some 15-20 years ago I planted two rows of grapes (8 plts. to a row) and they took off very well. I can not remember now what routine we used a lot of compost and my 160lb. BullMastiff continued to help with that up until 15 years ago.
