Hey ya RichEd,
How's it goin'? I have 2 DP Blueberry that I'm starting to flush now at 60 days flower. Easy to grow, easier to clone and a pretty good up high. Vegging for 8 weeks you should expect a large plant. My Blueberry is not the bluish/purple pheno, but does well in hydro and has a sweet taste. I average 2 oz. dry per plant when I veg for 6-7 weeks under HO T5's. Not a big yielder, but good buzz.
This is my 5th grow of the DP Blueberry. I also have DP Strawberry Cough and White Widow and Parsdise Seed Dutch Dragon. I liked them all so far although the SC has been tough to clone.
Good luck. Go Green...Grow Green
