Chill

VitaLink Chill is an advanced biostimulant formulated specifically to protect cannabis plants against heat stress — allowing growers to achieve good results even when grow room temperatures climb past 30°C and toward 40°C. It contains betaines, which are natural osmoprotectants that play a key role in protecting plant cells from damage caused by heat-induced water and osmotic stress.

By building up protective compounds in plant tissues through regular use, Chill helps plants maintain cellular function, photosynthesis, and nutrient uptake even in conditions that would otherwise cause visible stress symptoms (leaf curl, wilting, reduced growth). It can be used preventively throughout the grow to build tolerance, or reactively when sharp temperature rises occur.

Apply at each watering as part of your nutrient program. Compatible with all base nutrients and growing media. Particularly valuable for outdoor summer grows, south-facing grow rooms, or any setup where cooling is insufficient. Made by VitaLink, a UK nutrient brand known for technically precise plant health products.
