Sativas are such a pain, they are the reason I started doing scrog in the first place. The flowers get so dang heavy on those thin little branches they end up producing less when they have no support. The hormonal change that stops flower production in sativas is so much more abrupt, you go from crazy budding to a dull crawl as soon as they send the signal that weight is getting out of control.
Don't get me wrong, sativas taste great and can be very useful for those that need marijuana for more psychological reasons but I gotta say (without trying to turn this into a "what strains are best thread") there are plenty of hybrids out there that have great sativa characteristics and retain the indica growing/flowering patterns.
Now lets get some more bud porn going, anyone seen any crazy colors lately?
