Most gardeners living in Northern climates fall into one of two categories. There are those who garden year-around with the aid of a greenhouse and those who wish they had a greenhouse to garden year-around with. That said, some gardeners would be happy with just a three season greenhouse to protect their young seedlings from a surprise frost or violent storm early in the growing season. Whatever the goal, greenhouse kits are often the first option considered due to their cost-effective and simple nature. An entry level greenhouse kit can start around $800.00 and can prices can reach as high $5,000. With Harbor Freight's greenhouse kits undercutting the competition by more than 50% we had to ask, what exactly are you getting for the money?
