Natural Power. Serious Flower Density.

ROIDZ is a high-strength bloom additive designed to maximise flower production, stack on weight, and drive faster development during peak flowering.

It uses natural, plant-derived PGRs alongside aminos, trace elements, and fulvic acid to deliver fast results with a clean, natural edge.

Whether you want to control stretch or add serious density later in flower, ROIDZ gives you a powerful tool to push quality and performance without resorting to harsh synthetics.

Apply at 1–2ml per litre in weeks 2 and 5 to reduce vertical growth and increase early structure – or in weeks 5 and 6 to target flower density at the most critical stage.

Best For

• Indoor and greenhouse growers chasing top-shelf flower density
• Growers using PK boosters – works alongside most bloom additives
• Natural-leaning setups avoiding synthetic PGRs
• Performance-focused growers aiming to control stretch or add late weight
