In April the greenhouse was glassed with help of plateaus. The warmth storage-tank of 250 m3 arrived and in the end it all just fitted. In the greenhouse kilometres of wires were pulled for the screen-installations. The screen itself was installed as soon as it could not get dirty in all the activities. Only at the end of April the greenhouse itself was done. According to plan the earth was smoothened superficially on Queensday, April 30th. When everything was done, the installations in the greenhouse could be worked upon.
