The D/T flavour is different from Cinderella's...more like black licorice whereas C99 is like tropical fruit. DTC99 has blended them into a really delicious combination. C99 is stronger in potency. You have a 50/50 chance that the phenotype will be D/T. I'd say you're almost sure to get one female of that type in each 10 seed pack. Sly has been RAVING about the Sugar Blossoms & I can vouch for it's mother "Genius" being OUTSTANDING so you may want to consider SB! You should use 7500 lumens/sqft. IOW, 1000W covers 16 sqft & 400W covers 9 sqft.
