Although every now and then people talk about some friend they know who had a successfull PC grow, nobody has ever really said that they themselves has managed to do it. The space it too small to really flower in, it could only really used for vegitation for a week or two. There is somebody on the site right now preparing a PC grow and everybodys watching cuz they wanna see whatll happen. My advice, stay clear of the PC grow and make yourself a bigger box if you want to finish flowering or end up with more than 4 grams after 3 months work. If you need any help, let me know.
