The greenhouses are where lessons usually take place. But when there are no lessons being held, they are a place for students to come and get some grardening, researching or looking around done. This would actually make Professor Walton happy.

However, you will notice that there are seven greenhouses. In each one a different variety of plants is being kept. The ones that are easy to deal and work with are in the lower-numbered ones and as the number goes up the plants become more dangerous and would require more experience and credibility to handle. So you won't need permission to access greenhouses from one to four but you will need Professor Andrew's permission to access the greenhouses five, six and seven.

As you enter whichever of the greenhouses you will see rows and rows of plants neatly tidied and positioned in an accurate spot in regard of sunlight. A few of them will occasionally need to be turned around, trimmed and taken care of and that's what you will find Professor Andrew doing should you run into him. He also will be roaming around keeping an eye out on things and people.

You are not allowed to harm any plant in any way. You must always be prepared for anything and if you need the Professor's help all you have to do is call for him, he's either in his office or in one of the greenhouses. Also, you do not need to bring equipment with you because in each one of the greenhouses there is a cupboard that has everything you might need; gloves, robes, shovels, pots of all sizes, cultivators, fertilizers...etc.
