It is hard telling honestly. ACE seems to be one of very few breeders that actually offers tips on their strains other than "performs best in SOG or SCROG" "Grows best untopped" "suitable for indoor/outdoor growing".Yes it is....but I wonder how many actually read the breeders notes on the strains they offer. ACE tells people to run it at 11/13 to help prevent reflowering. Supposedly likes lower nitrogen levels as well. I wish I had put her in 2nd run soil honestly but I used all that on the outdoor girls.
