How to autoflower Scrog

Before autoflowering Srog, it is critical to ensure that your autoflowers have reached the desired height. The screen should be placed anywhere between 15 and 30cm below the desired height of the autoflower strain.

The training session should continue until you keep the first pre-autoflowers in your desired shape.
