Greenhouses are limited in space, and are quickly filled with plants.  Large vegetables like cucumbers and watermelons are often not grown in a greenhouse because they require much space.  Our benches are no different in the greenhouses.  In order to grow a cucumber this year we are growing vertically.  An English cucumber seedling was planted in the bottom of a bucket and grown upside-down.  English cumbers will typically pollinate on their own which makes them a great candidate for a greenhouse.  The plant seems to grow slower and now that it is August we have our first cucumber starting to develop.  Since the fruit is inside a greenhouse, the delayed start time will not matter.  It can continue to grow well into the fall months when the greenhouse remains warm.
