you can grow on your windowsill but have some other kind of light on when the sun goes down so you get 18 hours instead of 10 to prevent early flowering. I did this with about 7 hours of sunlight and cfls only during sun down. Ended up with a 4 foot plant but only about 1/2 oz. I would have yielded more but too much nitrogen in the miracle gro soil and the cfls did almost nothing besides tell the plant it is not night time. Hope this helps.
michaelpeg Reviewed by michaelpeg on . Window Sill Growing Hi all, thanks for reading hope you can help me out. I want to grow because I have no budget what so ever right now and I enjoy a good smoke every now and then. I cannot plant outside for various reasons. But I think I'm in luck because the sun shines on my window for hours a day, but that's risky I suppose. I want to grow on my window sill in my bedroom with some regular plants to make it look less supicious and so my family wont take a second look if they come in my room while I'm away. Rating: 5
