The unusually wet weather hasn't dampened Drysdale's enthusiasm for growing hemp.
"It's exciting, I'm prepared for a complete and utter disaster, but anything short of that and I'll be a happy man."

Hemp fibre has many uses but Drysdale says the problem in New Zealand is there is no infrastructure or facilities to process it.
Before he signs off to do battle with the elements on his farm, Drysdale has one more important piece of information to impart.
"We should no confuse hemp with marijuana."
