Frame Steel Galvanized Multi-Span/Plastic Film Greenhouse with Hydroponics Irrigation System for Strawberry/Flowers/Vegetables

Cucumbers grown in a greenhouse are always grown for fresh use and not for pickling. Slicing varieties are longer than varieties grown for pickling.

In a commercial greenhouse, a wire is put up going from one end of the greenhouse to the other about 10 feet above the plants. Then individual plants are run up to the wire using twine. Plants will naturally climb the twine, but some training is done to make sure it stays climbing its assigned twine, and plastic ties are used to strengthen the plant.

The most common method of greenhouse growing with cucumbers is the Umbrella System. In this system, all side growth is pruned, leaving just the main stem growth until the plant reaches the top wire. Then, once the main stem reaches the wire, the topmost growth, or terminal bud, is removed and the last two lateral branches are allowed to grow sideways and downward.

The growth from these lateral branches will be allowed to hang down up to 3 feet from the ground. The main stem will also produce fruit, but the first 3-4 feet at the bottom will have been pruned to prevent more vegetative growth.

Another system that's gaining popularity is the High-Wire System, sometimes called the Hire-Wire System because it's more labor intensive.

In this system, the top wire is set higher, around 15 feet and the cucumber plant's top bud is allowed to grow until the top of the wire and then pruned back keeping all growth along the main stem.
