No offense, but... A quarter lb a plant? In a 4 x 4 x 6.5 tent? LOL!!! All plants yield differently, so saying if you get 4 decent cutting you should easily get a pound is not realistic at all. I would say he should expect to get two ounces per plant on average at best, especially with the limited space in a tent. Unless you want to go SOG, the above mentioned method of growing with a smaller amount of plants is definitely the best way to get a higher yield IMHO.
