Step Six Install a Vent

Pipe Insert Into Roof

A vent fan is necessary in virtually all grow rooms. See Air Ventilation and Air Ducting in Chapter 9 for more information. Most grow rooms require some sort of odor control (see Step Seven, page 146) to keep it secure from cops and robbers.

Twentytwo Large Grow Rooms

The first photo was taken in the vegetative growth stage when the plants were about a foot (30 cm) tali, just before they were induced to flower. The garden is in the corner of a spare bedroom and illuminated by two 400-watt metal halide lamps. Clones were transplanted into three-gallon (11L) containers of soilless mix. Note the small envelopes of beneficial insects clipped to the containers on the lower left. Here is the same garden after a few weeks of...

The budding clones are growing in one-gallon containers of soilless mix and sitting in 10 x 20-inch (25 x 50 cm) trays lined with a plastic grate to facilitate drainage.

The grower could have waited until plants were a little taller before inducing...

A space above contains electrical appliances including the ballast for the lamp. A space below the growing bed serves as a storage area. This is a good garden design for...
