Where did the bitterness come from?

There are several reasons. The main reason is the fact that cucumbers do not grow in perfect conditions and the biggest culprit is a fluctuating temperature. This phenomenon widely occurs in greenhouses because temperature can rise very quickly. That is why greenhouses must be ventilated as often as possible. The chemical substance responsible for the bitterness is called cucurbitacein. Keep in mind that cucumbers must be watered properly. They love water and moisture. Use nitrogen-based fertilizers at the beginning. The unpleasant bitterness is also produced during the final stages of cucumber growth.
