Big Bud is a guaranteed, power-packed hydroponics formula containing amino acids and other special ingredients that nobody else uses or even knows about. Big Bud’s amino acids, nutrients and other special ingredients go directly to the cellular-level mechanisms responsible for floral growth. They ramp up these bloom-making mechanisms so more and bigger flowers are produced.

This top-rated, easy to use, bud-boosting formula forces plants to devote all their energy and resources to making massive flowers. Big Bud accelerates flowering and establishes more flowering sites. So you get more flowers and they mature earlier so you get more harvests of bigger buds per year. That means more profits, and more efficient use of your hydroponics garden, electricity and other operational costs.

No other bloom product outyields our time-tested, garden-proven Big Bud formula. We made this product specifically for the kinds of plants you grow. That’s why we guarantee bigger yields- or your money back.

Big Bud is constantly tested against bloom products made by competitors. Not only does Big Bud outperform the competitors to create an average 44% increase in bud size, but testing reveals that their “bloom boosters” actually decrease harvest yield and quality.

Gardeners using our competitors’ formulas are shocked to see their buds stall- or actually get smaller. But when they use Big Bud, their buds swell up like balloons, right before their eyes!
