Jack Flash (sensi) What to expect

I've just started some Jack Flash and wondered if anyone has grown it and could tell me how big it can get and anything else i might need to know. I've done Jack Herer twice and have been really pleased with that but i wanted a change but still keep some of that Jack taste/smell and high. Sensi say its great but they would say that. I've seen threads about jf but they were from clones and i'd like to know what they're like from seed, different phenos and stuff like that.
Thanks

Anyone there?

I'm currently growing Sensi Jack Flash.
My mothers are 18-24 inches tall and about 24in in diameter.

I flowered out a Mother in 3 gallon hempy and it ended around 4-4.5ft and 24in in diameter.

I am currently SoG them, and they finish around 36in in height and 8-10in diameter. (I lollipop them)


Check out Old Frog's Grow journal. He's got an INSANE setup going.

Thanks mj. Did you have much variation in plant type from seed?

ive never tryed jack flash but if its anything closly related to jack herer than yes i would def say do it jack is overall best smelling bud ive ever smelled and great long lasting high idk about groing good buds but id do it if i were you

I've already done a couple of grows with jack herer and you're right it is fantastic. I've got 3 jf in the seedling stage atm and i've also just put in 2 ghsc super silver haze. Thanks for the replies

They veg pretty uniform in my setup. However when you flower them, you will see the two main pheno types show. One is definitely a shorter more indica pheno. The other is taller and less busy.
