Mail Hydroponic Culture of Cucumber Cucumber is a vine crop that can be very prolific. Just two plants in a tub will take over whatever corner they are in and will vine up all over the space. They are best placed where the tops can reach an eve of the greenhouse and they will produce two to three cucumbers a day. The plants then need a vine support to keep them suspended in the air, and this support should be quite strong. Pinch out the top of the cucumber plant when they reach the top of the growing area.
Cucumbers can grow to full size in a day or two.
It is important to pick them while they are green and not wait until they turn yellow and old. Pinch out the tips of lateral branches two leaves beyond where the fruit has formed. Most varieties have male and female flowers and have to be pollinated by hand. This is accomplished by using a paintbrush from the middle of each flower. The female flowers have a bump behind the flower.
