Let me give you heads up, Nirvana has pulled all the new AF are not selling them anyone. I've been in contact with them about these AF and they have agreed that the seeds they sold are not viable. They takes months longer to finish, grow way too big, and ofter fail to flower. If you are growing a Nirvana AF and your plants are less then four weeks old, you would be better off pulling them now. MY NL AF are over eight weeks old and still do not have any bud sites. If I had purchased normal seeds, and flowered them in the third week, I'd have three week old fowers/buds on my plants now. If taking five months to harvest indoors, while getting half the yeild (if they decide to flower at all) is acceptalbe, then let them grow. If they are less the four weeks old, you can start a new grow, finish at the same time, while getting twice the yeild with no risk of flower failure.
