Ive been growing Nirvana ICE for awhile now and thus far my experience has been little diff. from yours. I have very good luck with the seeds from Nirvana germing quickly and female to male ratio is good. The plants grew fast,good n bushy, many branches. It cloned easy and the clones grew fast as well. The bud was not that leafy was very hard w mostly straight solid colas. This shit is so covered w super white trichs from the 3rd week its unreal!! Stinks fruity tootie at first and then quickly turns to stinkyass body oder!! The high is VERY narcotic like and last awhile. Taste is harsh but good.I found that the bud was dense,heavy,great quality but not quanity.I found after cloning it seems to take longer to finish. Does clone very easy but easy to over fert. My oppinion is if you want good head smoke go for it but if you want to produce I would shy away. HAPPY GROWING!
