Starting a six plant medical garden

Soft Secrets

I recently got my medical marijuana card and want to start a 6-plant garden. I have a flower area 140 cm x 110 cm x 170 cm tall, lit with a 400w HPS. Is that enough light?

Your garden has an area of about 1.5 square meters (M2). To grow high quality buds, plants require an adequate amount of light. Varieties differ in the intensity of the light they need to produce bountiful yields of high quality buds. Indica type plants require at least 500 watts per M2. Indica-Sativa hybrids need at least 575 watts. Sativa-Indica hybrids require about 650 watts per M2.

Use high-pressure sodium (HPS) lamps with reflectors that direct the light down to the plants. If your garden is filled with Indicas, use a minimum of 750 watts. Lamps of this wattage are not generally available. Instead, use two 400-watt lamps, or increase the yield by supplying more light. If they are available in your area, switch to a 1000-watt lamp.

For the Indica-Sativa hybrids about 900 watts of light are required. There are no 900-watt lamps so you could use either a 400 and 600-watt lamp or a 1000-watt lamp if they are available.

The Sativa-Indica plant garden requires a minimum of 1050 watts. You could skimp a little by using 400 and 600-watt lamps together or a single 1000-watt lamp. The plants produce more with more light so you might consider two 600-watt lamps.
