Training melons and watermelons to grow vertically is referred to as trellising and is one of the advantages of growing melons in a high tunnel. Most melon cultivars and personal size (less than 7 pounds) watermelon cultivars are amenable to trellising.
A direct public offering (DPO), like the more traditional IPO, is a stock's introduction to the stock market. The stock is offered to the public for the first time. Unlike an IPO, which utilizes an underwriter to sell shares to the public, DPO shares are purchased directly from the issuing company.
For a company, an IPO can offer great flexibility compared with other forms of capital raising. A bank may only loan money secured against assets such as property which can be sold if the company were to fail. But many small and growing companies may not have enough security to offer.
