How fast do i grow

[Iammygod]

Hi.

i wanna know how fast(or slow) i grow. Actually i need to know my speed.

my clones are 34 and 40 days old; big ones on the pics are older. It's 7 days after ive initiated 1212 cycle. They cover 2.5×2.5ft now; 4 plants

Your plants look very nice and healthy. You might want to thin them out some. I always like to see daylight through the plants.
You will start seeing tops at about the second week after you switch to 12/12.

The only one that can tell how fast they are growing is you. Take another pic in a couple of days and compare.

Fast when compared to pumping cold molasses, but slow when compared to the speed of light. 😋
Really, it is genetics that determines how fast or slow. So if all elements were the same as last grow, just ask yourself if it took longer or shorter to fully fill in your canopy?

2 day later
How is the shape of my 3×3ft canopy? One push left reaching 3.5×3.5ft.
taking pic is a good practice.

Because of the effect of RH and light level in Leaf Surface Temperature its hard to make tempeture to work for you without a temperature gun. Do you use IR thermometer in the garden?

It's 11 weeks after taking 4 clones. 2-3 weeks left until harvest. Unfortunately It's going to be my last cannabis grow. 5 times in 2.5 years
