Pretty sure haze is a sativa dom strain height will deff be a problem as it grows tall
Haze strains are sativa dominant, noway you're gonna manage to grow that in a stealth box.
I highly recommend White Widow, and cut off the growing top at the 4th internode, that way they stay really short and the quality of smoke is top notch too, other than that, you could find another Indica dom strain and just start 12/12 after two weeks of veg, but cloning is your best bet, I used to clone my Manadala seeds Speed Queen, and as soon as my cuttings rooted I stuck them straight into my small flowering wardrobe (it wsa only 4 1/2ft square so it was really small) and I would end up with these single koala plants that were ready to chop anywhere between 8 and 9 weeks.
Here's a link to my old grows inside my flowering cab, and you can see the end result after harvest too in one of the vids:

Sorry for the ancient thread revival, I just wanted to put my 2 cents in.
But no haze is wise to grow inside small growing enclosures as they will grow way too big and you'll run into all kinds of problems mate.
Stick with Pure Indica's or Indica Dominant strains for small growing areas, and if you are capable of cloning then I strongly recommend that you go down that route too as it's a lot quicker, and the plant growth seems to be a lot more uniform when growing from clones if you stick them into 12./12 straight after they've rooted.
