Jack 47 XL Auto - Putting Cannabis Production into Cruise-Control

The Jack 47 XL Auto strain comes from a long line of careful selection. It’s currently on its 3rd generation, and this autoflowering beauty is notable for its tall stems and abundant resin coverage. She grows with extreme vigor, making her one of the best strains that your stable will ever see.

Growing Information

Since this is an autoflowering strain, it’s essential to understand that you won’t get to dictate a vegetative or flowering phase.

Don’t underestimate the yield potential because this plant is an autoflowering strain. You can expect upwards of 600g/m² of highly potent flowers. Since Jack 47 XL Auto finishes so fast, you should grow her in the SOG style.
