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.
nice looking plants you have there.
Yes my CJ are Dina-fem seeds and I believe they are primarily sativa and thats why it is so tall. Its been under 20/4 light since seed and has been a monster of a plant and I have it partially pied down too.
I added a small fan inside and also raised the lights a few inches so it should help with the heat issues around the top of the plants. I am maxed out on raising the lights.
here are two pics of the Critical Jack - Very nice buds
here is one of the Pineapple Express- this one is starting to fill in nice.
