When warm days occur the saslies can be uncovered, and the sun allowed tc 
shine through the glass on to the plants, but until February it is better to keep 
them in darkness, and not admit fresh air oftener than once in two or three 
weeks. Do it when the air is most genial, and raise the sashes only long enough 
to inspect the plants, and if very dry give a little water.
