My plant wont grow in height!

Welcome to the world of disappointment that autos can be.......... stick with much superior photoperiod plants in the future, you can then control when they flower. Not much you can do with this plant for now, just keep loving it and harvest what you can.

That is a shorty. Change how you look at it. This is a learning plant. Grab some wire,try LSTing branches down, let in the light. They might be getting everything they need right there, if you move the light away, they have to reach for it, they grow. 40cm seems goodish. Good luck

internode length is short... you applied more light than you wanted if you wanted more stretch... more is not always better. might not matter much now, but i'd raise light 2-4" to start... see how it goes and maybe adjust again - either up or down depending on what you see, how much you raised it to start.. i see it is listed as 6" form canopy? what kind of light is this? if a quantom board or anything with centralize light source or diodes all clustered together, raise to 20-24"... things that better distribute light can be closer.

High bro! This plant actually looks great!!! This is an Indica strain and when she starts to flower she will still double her size. Here is the breeders information about this plant: This unbelievably aromatic autoflower literally explodes into a pine flavoured Christmas tree in a mere 75 days, producing an abundance of glorious kushy flowers covered in huge amounts of juicy trichomes with a final height indoors of 80-100cm So your plant is doing a great job and will grow big, fat and juicy buds bro! Happy Growing! 😋

She's not gaining height because she doesn't need to - plants stretch to reach the light and you've got your lights far too close to her - so she doesn't NEED to grow tall! Move the lights up to about 18" away from her and she'll start growing. She'll ALSO stretch as she goes into flower. You'll be fine - good luck!

It's looking OK now its doing brilliant now happy growing
