I am growing some blue dream also. They are a great strain for yield, taste, and quantity. Probably one of the most well rounded buds I have seen grow.
I am 42 days into flowering. I just added the hardener and a sweetener. Along with a new product that is amazing. It is called snow storm, by humboldt county. I added a day and a half ago, the guy at the store said I would have crystals everywhere within three days. This morning I noticed crystals on the sun leaves close to the stem. The buds have gotten a lot more on them as well.
I didnt do much research on this strain because a buddy of mine, whom I am finding out to be kind of a bullshitter, told me this was a 10-12 week strain. I figured out about 4 days ago that it is a 8.5-10 week strain. I hustled down to the store and bought the hardener but had to skip the big bud. Kind of pissed but the plants still look great and are going to yield a descent amount anyway.
I look forward to seeing how yours turn out.
