Unstable prices of cucumbers

Each year prices of glasshouse cucumbers are changing all the time. The main reason of such situation is weather.

 It could have been noticed in last few days. At the end of May there was a high volume of glasshouse cucumbers what caused price drop. On May 30 long cucumbers cost PLN 1.00 - 1.60, short PLN 1.30 - 2.00.

However very soon prices increased. Currently long cucumbers cost  PLN 1.20 - 1.50 and short PLN 1.50 - 2.50. It's obvious that these prices won't remain stable.

There is a good weather in Poland and prices will drop again.
