Hi everyone. I started my seeds in rock wool a week ago, but don't really know how big the should be before moving them to the tower garden...any advice?

Hi braggie.
Don't know what a tower garden is, are you vertical gardening?
Got any pictures?

You can find lots of pictures on Google. A tower garden does not seem like a good choice for cannabis plants.

Interesting, looks great for veggies but not sure a 3' plant will work very well
