how many lights do i need?

I have been growing 3 plants outside and ive been worrying about my neighbors being nosey so i would like to know what lights/Watts i would need and any other info to make a successful indoor grow room

get a 400 watt for 3 plants. you'll be fine.

what kind sodium or CFL? i would like to go with CFL's and how many bulbs and or watts would i need? also could it be cost effective?

• Efficient. They put out more light, with less energy usage, than any other type of illumination available to indoor growers.
• Bright. HID's produce more light than other types of indoor horticultural lighting.
• Expensive. HID's cost more than flourescents. They range in price from $50-$600 dollars.
• Hot. HID's produce considerably more heat than standard fluorescents.

Fluorescent lamps are:

• Inexpensive. Shoplight fixtures can be purchased for as little as $7. Compact fluorescent bulbs only cost a couple of dollars a piece.
• Locally Available. Most discount stores and home improvement stores carry inexpensive, fluorescent fixtures and bulbs.
• Fine for vegetative growth. Fluorescent bulbs put out plenty of light for plants growing vegetatively, including mothers, seedlings and clones. Some growers prefer fluorescents for vegetative growth because of the slower pace of growth and better root development.
• Fluorescents need to be in close proximity to achieve their rated output, which means their canopy penetration is more limited than HID's.
• Comparatively inefficient. 10 forty watt fluorescent bulbs use the same amount of energy as a 400 watt HID, but produce far less light. Since they use the same amount of energy but produce less light, the remaining must be given off as heat. Contrary to how it may first appear, fluoros actually run hotter than the equivalent wattage of HID-- they just disperse the heat over a wider area.

get a 400w hps light AND get a 400w conversion bulb, that bulb basically makes your hps into a mh for veg, then just switch the bulbs and flower away

Thanks what about for the flowering cycle do i need special bulbs or can i use these for 12/12

they said it all

Yeah HB, I started out with CFL's and upgraded with an HPS.
You just cant beat a 250w or a 400w Sodium bulb. They will produce you some very good bud compared to CFL's.

You want to Vegg under fluoros or Metal Halide and Flower with sodium bulbs or Warm spectrum CFLs.

400w
Hps bulb


CFl bulbs



But either way will work.
good luck though man.

k thanks joe im going to go with a 250watt sodium bulbs
