Lineage: Secret Formula x Leeroy OG x GG4 // Aromas: Gas, Kush, Sweet // This is one secret that's too fire not to share! Secret Fire is a relaxing, stoney Indica triple cross of Secret Formula, Leeroy OG and GG4. Notes of gassy Kush and sweet earth give the strain a unique and inviting aroma and flavor, as the heavy knockback helps you melt into your seat and relax after a long day.
