Although high from the final product is pretty amazing, growing Arjan's ultra haze #1 is the biggest goddamn hassle i've ever had.
The strain takes at least 17 weeks to mature, will burn up like crazy if you even think about giving it food, and foxtails out later in flowering.
It is pretty much impossible to keep the fan leaves alive through flower. I even exchanged a couple messages with Franco from GH about this, he advised exphasizing calcium in early flower and shifting towards an emphasis on magnesium later in flower. My independant source of calcium and magnesium is calmax, which has cal and mag, so I haven't been able to follow his advice to a T, but I did try upping the dose, lowering it, etc. with little success.
The smell is very hazy and pine-ey, and the high is a soaring and is an energy buzz. But unless you live in a tropical climate and can let this girl grow to her potential, I'd say don't grow it. There are plenty of early finishing sativas that offer a much more pleasant indoor growing experience.
I can't really call it crappy, because the smoke is pretty good, but I'm just finishing flowering out the last clone I have of it, am I'm not gonna miss it when its gone. I've got too many other good, easy to grow strains to bust my ass on this one.
