Ok so a quick run down... a friend of mine is growing in a Stinkbud style aeroponic system, he has 4 afghan kush in there and turned them to 12/12 over a month ago and for some reason they haven't produced any hairs or anything. He's used this system before years ago and never had an issue, any one have any idea of WTF is going on? All nutrient levels are fine and plants look healthy, perhaps slightly stretched i suppose but thats due to the time mostly. The clones were taken from a mother plant grown from seed. It gets a bit hot in the area they are growing in but they seem to not mind that at all. Any ideas or anyone had this happen before?
