Don't mean to jack the thread but I live here in mid michigan and it's my first year as well. I have three baby girls, about four and a half foot tall each. Two are supposed to be some kind of hybrid that grows and buds quicker than other varieties, and is supposed to work good in this climate. But I am too much of a newb to tell you what they are exactly. One of them is just from a pile of seeds I germinated that were laying around. It's not a five leafer like the other too and isn't as far along as the other two. I saw that you can cover them to help speed them up. So my question is, what do you use to cover them and not hurt them. They are so beautiful I would hate to screw up the slow one, but then again, I would rather try and get something than have it take forever and not get anything. So what do you use? Black plastic bags? Or like burlap? Let me know please.
