well, if you just go and look up the solar and lunar cycles for the strain you have, sativas flourish in an equatorial timeline, indicas and kushes, go from 14/10 to about 10/14 in the higher latitudes. this is a variance of about 15 minutes a week, that can be simulated with reducing the number of pins pushed in on your timer by one each week(if u got a cheap one). your plant will grow bigger and bud more as a result, but is it worth the time or energy, thats the question. most people turn and burn indoors, and rightfully so, energy and equipment is expensive and bud is getting cheaper... as long as the days are getting longer it will grow, as soon as the days start getting shorter it blooms, the growth rate of the plant is sped up indoors with sudden and abrupt change to 12/12 from 24/7, which is why alot of strains herme and alot of people grow larfy sativas indoor. the plant hermes because of a natural tendency for all female plants to reproduce, they will sprout bananas and self pollinate, also because you forced the plant into flowering on an unnatural scale the buds never fill out and in appropriately, thats why everyone grows indicas/or indica dominate strains indoors, they are more adaptive to the harsh chhange to 12/12 bc of their already shortened grow cycle due to freezing and light degredation in the higher latitudes. sativas that grow on the equator will grow and flower in 12/12 for 365 days with barely a change at the solstices. but they also grow all year, but they also grow like 20 ft tall in the right conditions. the buzz and resin on landrace sativas from the equator is unparalleled but you wont find that shit in these parts unless you have a supreme hookup, because aint noone growing pure sativas indoor bc they always turn out larfy and they herme like hell.
