Description
SENSI GROW A&B 1 LITRE is the trial and single-cycle size of Advanced Nutrients’ professional pH-Perfect vegetative base nutrient, giving UK hydroponics growers the opportunity to evaluate Sensi Grow’s formulation quality and unique buffering technology in a small, low-commitment quantity before upgrading to the 4-litre or 10-litre format. We have been recommending Sensi Grow to UK growers since 2017 and the 1-litre twin pack is the natural entry point for growers new to the Advanced Nutrients system.
Everything in the 1L That the Larger Packs Offer
The Sensi Grow A&B 1-litre format contains the identical formulation as the 4-litre and 10-litre twin packs — the same pH Perfect chelation system that buffers solution pH in the 5.5–6.5 range, the same nitrogen-dominant vegetative macronutrient profile, and the same chelated trace mineral package that maintains enzyme function and chlorophyll production throughout the vegetative phase. At 4–8ml per litre of each part, the 1-litre pack provides 125–250 litres of nutrient solution — adequate for a full vegetative cycle in a small DWC system or a single reservoir top-feed application in a coco or soil medium. After experiencing the results, growers consistently upgrade to the larger format for better value per litre in subsequent cycles.
Using Sensi Grow 1L for Best Results
Begin at 4ml per litre of each part for young plants (EC 1.0–1.4), increasing to 8ml per litre per part for established vegetative growth (EC 1.6–2.0). Always add Part A first to the reservoir or mixing vessel, mix, then add Part B — never mix the two concentrated parts together before dilution. The pH Perfect buffer will stabilise the solution pH, but always verify with a calibrated pH pen. Sensi Grow pairs with Voodoo Juice for root development and B-52 for stress resilience and vigorous early vegetative growth. Switch to Sensi Bloom A&B at the start of the 12/12 flowering photoperiod.
Try Sensi Grow A&B 1 Litre with Voodoo Juice and B-52 to experience the Advanced Nutrients vegetative programme, then upgrade to the 4-litre twin pack once results confirm this is your nutrient system of choice.
