How fast does an Autoflower grow?

I have one 3 or 4 days old and it just got its second true leaves. What can I expect for growth over the next few weeks? The strain I'm growing is Afghan Kush Ryder.

I'm pretty sure they just go straight into the flowering stage, wich is why they finish so quick. But look up at the breeder's website of where you got the Afghan Kush Ryder, it should be on there.

Heights is dependant on te genes and growing conditions. Most strains won't autoflower on a 24 hour light cycle. You need to use 20/4 or less.

it grows at the same rate as a normal plant, it just flowers faster and doesn't need to change photo-period.
