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.
The benefits of buying the shares in IPO is you get shares at discounted prices than other investors who purchase it from the market which will help you in gaining more income than others. But the problem is will the IPO be undersubscribed or oversubscribed.
