never had much look on my windowsill to be honest, not to mention the risk of nosy neighbours(unless your secluded of course) found they veg'd quite well in window but due to lights been turned on in the room on a night time etc they never really grew much taller than 12 inch and never went into flowering, to be honest i didnt expect much anyway just had some seeds that i found kicking about and chucked em in a pot was suprised they actually grew.. if you can grow them safely on your window sill why not stick them in the garden weve got the weather for it at the moment.. dont expect great things though im no expert and ive given up growing due to those pesky pork choppers, things have changed alot since i grew, just thought id give you my input! :thumbsup:
