Grosputt™ GS-4 products contain Gibberellic Acid (GA3), a potent, organic plant growth enhancer used successfully worldwide for over 40 years. Comes in a 100ml concentrate bottle.

GA3 naturally occurs in all plants. GROSPURT uses a unique extraction process and stringent quality control to ensure the quality and purity of its GA3 products. GS-4 is an easy-to-use water miscible liquid that evenly disperses the product when spraying to maximize uptake and absorption.

Until recently, GA3-based products have only been registered for use on cherries and seed potatoes in Canada. Now GROSPURT’s GA-4 is registered for use on a wide range of fruit, vegetable and floriculture crops in Canada.
