If you plan to grow indoors

Invest in an HID light! (Metal Halide for leafy plants - HPS for flowering & fruiting plants). I use a 400 watt metal halide lamp with reflective hood to light nearly four gardens simultaneously and with excellent results. Since HID lights aren't exactly cheap, you may choose to substitute high output fluorescents instead, but in the long run, you'll get more light output and certainly more yield with an HID lamp. Either way you grow, try to get at least 20 watts per square foot of garden for best results. I prefer 30-40 watts per square foot of garden as the extra light makes a BIG difference. On the following page I briefly describe each system you can build. I recommended the lamp sizes based on the growing area of each respective garden. If you were to illuminate more than one garden at a time, you can use this simple formula to determine your lighting requirements. Multiply your growing area width by its length and the result by 20-40 watts (depending on crop) - the result is your required lighting wattage. Standard indoor HID grow lights come in 100, 150, 175, 250, 400, 1000 and 1500 Watt sizes. Most high output fluorescents deliver about 10 watts per running foot of bulb. To achieve proper illumination with fluorescent lighting, use an array of 3 bulbs for every foot your garden is wide. For example, if your garden is 3' x 4' - use (3) 4' bulbs per foot of width - (9) 4' bulbs total. This will give you 30 watts per square foot - perfect! - keep them close to the plants too - 6-12" max. Remember, water and electricity are hazardous to your health! Follow safety precautions on product packaging and inserts. Keep lights and ballasts away from moisture! Use a fan to circulate air throughout your garden.
