I guess you could grow about 4-6 or so plants in there. You can get 3 foot florescent tubes where I live that are 30w. I had a bank of three of them for a grow they were quite cheep as well. You could look on ebay for some cheap HPS lamps as well you might get one for say £45. You need a bit of ventilation too. Maybee get a Desk fan in there or use the little pc fans you can get. Reckon the thing to think about is invest a bit of money on noy and buy an ounce or put it in to your grow and get a pound.:rasta: :thumbsup:
