if it's your first go at supercropping you might want to leave some grow natural just to see what the difference would be in yields and uniformity etc. all strains respond differently, and imo it has to do with more than just whether it's sativa or indica. for example some strains seem to harden off a lot earlier than others, and cropping these strains is a pain in the ass. you would think that indicas would harden first but i've had some very sativa heavy strains harden off halfway through veg. some additives like silica will cause the branches to harden early also. other strains pop back up too quickly to really get the desired effect. i had a chiesel plant last round that would be practically touching the light 3 hours after being pinched or tied. long story short, some plants like it, some don't.
