All are 3ft one is 102cm tall. Did not training so I’m guessing that why they grew so tall. Looks like great bud very frosty. Pic was from a few days ago, it is looking even better
That strain looks familiar, here is a pic of a little dwart auto nug, yours looks good you can keep them lower by keeping the light on top of them but allot of autoflowers strech thats there spurt, if you are running the same strain the plants should be fairly uniform but sometimes they run away on you lol
