It is a pretty even toss up between Blue Dream and New York Diesel. Both are easy to grow and good for a beginner, they produce nicely and have good genetics so the smoke will be good unless you really mess things up. The one thing I like about Blue Dream is it is a fast flowering sativa finished in 60-70 days of flower. NYD is more like 90 days but worth the wait. I am doing an indica grow this time with God's Gift and either King's Kush or Master Kush (cant remember which) so we will see how these go. So far they are bushy healthy little ladies.
