They say, hardly any stretch when induced to flower.

To me that says like nearly all normal weed, you should have a vegitative stage of at least a couple weeks, but more like a couple months, depending on your space available, etc. Then induce to flower.

It also says you can eliminate the veg stage if you want a dwarf plant. I think this is the same for most varieties. I know this is a common growing style for several people. You would only do this if you plan on compromising yield so you can keep them short and grow in a small space.
