Starting AutoFlowers: ? WhiteWidowAuto 2013

I just got my seeds and in a couple days will be planting them.
Should I start them in 4'x4' rockwool cubes? Has anyone done this with autos?
I know that they have long taproots, and are reluctant to transplanting, so it it okay to do?

I'm bout to do the same thing. Picked up some autos just to see how they generally grow from start to finish. Not to mention they were like $14 for 10 regular beans. Gonna start mine in Jiffy Pellets and just go strait to 5 gallon pots after their first set of true leaves. Unless the taproots going nuts out of the bottom then it'll be sooner.

i put my autos into root riot blocks with no probs i then transplanted them into small pots to let them get rooted then into their home pots im now only a few days from harvest
