SPOKANE, Wash. -- It may be called weed, but marijuana is legendarily hard to grow. Now
that the drug has been made legal in Washington and Colorado, growers
face a dilemma. State-sanctioned gardening coaches can help folks
cultivate tomatoes or zucchini, but both states have instructed them not
to show people the best way to grow marijuana. The situation is similar
in more than a dozen additional states that allow people to grow the
drug with medical permission.
