i think some of the effects of the strain you grow depends on how long you wait till you chop
i've had a couple of hashberry plants in my room for a few months and the last time i took them down i left them to ripen a few (8-9) days longer than the last time and the effect is a frying pan in the face knock out stone..
but lots of people report that its not strong enough for them
i think it has alot to do with you and the plant, how your body reacts to the particular strain/pheno and how you grow it
btw im not saying you should grow hashberry (im not any more for a few reasons yield being one) just don't get lulled in to whats written on the packet or what suits other people
i think most indica's, indica x's will knock you on your arse or lock you too the sofa if you grow them for that purpose
