Cyco Nutrients - Platinum Series - B1 Boost - Vitamin B1 for Stress and Transplant Recovery
Best for: growers who want to cut down on transplant shock and stress-related setbacks after repotting, cloning or heat stress.
Our thoughts
Vitamin B1 additives are a bit of an old-school grower staple, and there's genuine plant science behind why thiamine helps a stressed plant bounce back faster. This isn't a growth-booster in the flashy sense, it's more of an insurance policy for the moments your plants take a knock, repotting, a hot spell, a rough transplant. Keep a bottle around rather than expecting to use it every single feed.
B1 Boost delivers a concentrated dose of thiamine (vitamin B1), a natural compound found throughout plant matter, that plays a genuine role in plant metabolism. Thiamine is required for making thiamine diphosphate (TDP), a coenzyme involved in key processes including pyruvate dehydrogenase and transketolase activity, and it also supports the production of other important metabolites such as ATP and NADPH.
Beyond its metabolic role, thiamine is involved in gene expression regulation and how plants respond to stress, which is why B1 products have long been used around transplanting, cloning and periods of environmental stress, where giving the plant extra support can help it recover and carry on growing rather than stalling.
How it compares
Vitamin B1 additives are a long-standing category rather than a new idea, and B1 Boost sits alongside other established names.
- Superthrive is the best-known vitamin B1-based product in the hobby growing world and the one most growers have heard of even if they've never used it.
- General Hydroponics RapidStart takes a different approach (root-focused with hormones) but is often used for the same transplant/stress-recovery scenarios.
- House & Garden Root Excelurator overlaps in use case, though its mechanism is built around root development rather than thiamine specifically.
B1 Boost's advantage is that it slots straight into a Cyco Platinum Series feeding programme, so you're not mixing brands to cover this one job.
Usage guidance
Use it around the moments your plants are under the most stress rather than as a constant daily additive.
Transplanting
Water in with a B1 Boost solution shortly after repotting or transplanting to help support recovery during the settling-in period.
Cloning and propagation
Use during propagation and the early rooting period, when cuttings are at their most vulnerable to stress.
Environmental stress
Apply after a heat spell, a lighting mishap, or any other stress event where plants have taken a knock.
Dosing
Follow the dose rate on the bottle or Cyco's Platinum Series feed chart, as thiamine additives are typically used at low concentrations.

Our take
B1 Boost isn't going to transform a healthy, unstressed plant, but that's not really the job it's for. It's there for the moments when a plant needs a hand recovering, and the thiamine science behind it is genuine rather than marketing spin.
Worth having in the cupboard for transplant day. At a price that makes sense for what's essentially cheap insurance against a bad week.
