ROUND BULB!!!!! You mean ...an incandescant "normal light bulb"


Take it outside and smash it man.....Get a CFL It's a cheap bulb that doesn't need a "Ballast " like other light types....They are sold as "energy savers" and will fit into a normal light socket....CFL means Compact Fluorescent Light ...That will nurish a young plant for weeks ...But you MUST invest in some a HID lamp....HPS will cover every aspect of the grow...400 watt minimum [ IMO] but a 250 watt is ok for small cabinets...



If you by a 100 watt CFL your plants will look like a profesional's plants...But not for long.........HID!!!!!!!
