Your auto critical jack must the a sativa pheno. I've got one that I dubbed " The dinosaur", because the fan leaves look fookin prehistoric. Here's a shot of mine at 4 weeks just starting to bud. Grown under CFL's as well. Troutie's got one that looks like the twin sister of mine. He's got a thread under the auto section. I've checked out maybe half a dozen ACJ grows, and this is the first sativa looking one I've seen. Let us know how it smokes.
