The greenhouse may be raised on piers ...

The greenhouse may be raised on piers to compensate for a hillside or it may be built in tiers with steps between.

The foundation proper, however, must be level and firm.

A good, level concrete foundation pays dividends in insuring firmness.

Settling causes cracks in the glass; cracks cause dripping; and drippings make for spotted flowers-the grower's tragedy.

Additional firmness can be gained by sinking eight- to ten-inch bolts into the wet concrete of the foundation, and then bolting the mudsill into place.

The next choice facing the amateur is between the home-built house and the many available sectional, ready-built greenhouses.

Prefabricated houses, while possibly more expensive, are easily erected and may save money by eliminating the mistakes prevalent in the trial-and-error method of design.

There is the additional advantage that prefabricated houses are movable, being bolted rather than nailed together.

Greenhouse manufacturers supply detailed plans and all materials for houses to be erected by the grower or a carpenter.
