They're good juiced and used as a salad dressing. What i didn't like is how thorny the plant is. Has thorns all along the stems. Also it took over the garden. In tropics could be invasive weed. Big advantage is they are not stung by fruit flies, as are other cucumbers here.
For starting seeds use well drained slightly acid soil. Keep temperature and humidity high and well watered until seeds sprout. Very easy to grow given right conditions. If i grew them again i would use a trellis, rather than letting them sprawl on the ground. Too easy to step on sharp thorns.
