Cyco B1 Boost

Cyco B1 Boost is a premium vitamin B1 (thiamine) supplement that has become a go-to product for experienced UK growers managing transplant stress, rooting cuttings and supporting plants through any form of environmental challenge. Thiamine (Vitamin B1) is a cofactor in several key enzymatic reactions in plant metabolism — including those involved in carbohydrate metabolism, root growth and stress response. During stress events, plants can rapidly deplete their thiamine reserves, and supplemental B1 dramatically speeds recovery.
When to Use Cyco B1 Boost
B1 Boost is most effective during transplanting — the single most stressful event in a plant’s lifecycle. Roots are disrupted, the plant’s water uptake is temporarily compromised and new root growth must begin immediately. Applying B1 Boost as a root drench at transplanting provides the thiamine needed to support rapid root establishment and reduces transplant shock to a minimum.
B1 Boost is equally effective during cloning — applied at 1–2ml per litre in the cloning reservoir or as a foliar spray, it supports the enzymatic activity needed for root initiation in unrooted cuttings. Many growers also use it to support plants during heat stress events, overwatering recovery and after any significant environmental disruption.
