G10 (Gravitation #10) started as a substitute for Gravity but turned into something else. It’s not Gravity- it’s something MORE! Increases the size and mass of flowers. Seeing is believing! For even more drastic results, prime the pump with Deep Breath in veg and the first 2 weeks of bloom then switch to G10 in the 3rd week for a powerful finish. For maximum “Gravity effect” use with Sonic Bloom and Killer Tea. No PGR’s.
