Frees seeds grow(AUTOS)first indoor grow

Hey guys sorry ive been mia ..internet bill wasnt paid and ive had know extra money until yesterday..so im back!! Now a quick catch up of what ive been doing so ill keep it as short as able first i had choose to move 3 out of the 6 plants total im growing outside and 3 was to remain indoor so i did the obvious and being that i was growing 2 each of 3 different strains LowRyder 2..Green Crack auto...and Prime Shit auto i kept 1 of each inside and 1 of each outside and let me tell you wish i would have just kept all inside because i think when it seem all good night temp wise i had a 33° night hit 😵 and it stunted all three outsiders and i kept them out for another week and a half and seen very little growth so i made the proper adjustments to the tent and brought them all in yesterday and boy its like they all had a jolt of life all of a sudden lol ...now i know its not a pic that just shows my LowRyder girls but the very last pic is to show the difference in progression with the insider girls(3 plants on top) vs the outsiders girls(3 plants on bottom)..only 2 factors different between the 2 groups of 3..growing condition wise is.. 1st...The insiders have been splurging on added co2 since day one of veg... and 2nd..The outsiders had been exposed to the almost freezing night of 33° ..so yeah its been a crazy couple weeks but its all coming back together now ..cause i just spotted pre flower and its a girl!!!!only on one LowRyder right now tho the other will of course be behind a little due to some weather stress but she seems to be pushing through it now inside
