VitaLink Heat

Keep Plants Growing Through Cold Snaps and Overnight Dips

VitaLink Heat is an advanced biostimulant that helps plants cope with cold stress and sudden temperature drops in a grow tent or grow room. When temperatures fall, plants slow their metabolism, take up less nutrient and can stall - and a single cold night can undo weeks of progress. Formulated with betaines, seaweed extract and natural plant hormones, VitaLink Heat supports metabolism and photosynthesis under stress so plants in hydroponics, coco or soil keep building roots, foliage and flowers even when conditions turn against them.

Key Benefits

• Protects against cold stress and temperature fluctuations in colder rooms
• Betaines act as osmoprotectants, helping cells stay stable in cold conditions
• Seaweed extract triggers early stress responses to support recovery
• Natural plant hormones (gibberellins and auxins) maintain growth and side-shoot development
• Maintains nutrient uptake when cold would otherwise slow it
• Helps prevent flower abortion during colder flowering periods, protecting yield
• Suitable for hydroponics, coco and soil growing systems

Plants Stalling or Dropping Flowers When the Temperature Dips?

Cold conditions slow growth, cut nutrient uptake and can cause flower abortion in bloom, while a sudden overnight temperature drop weakens plant health and costs final yield. VitaLink Heat helps plants tolerate that stress rather than shutting down, supporting stable vegetative growth and flowering through the cold spell.

How to Use

• Prep: shake well before use and maintain pH 5.8-6.5 for uptake
• Hydro, coco and soil root feed: add 0.4ml per litre to your nutrient solution alongside your normal programme
• Emergency foliar spray: 5ml per litre as a fine mist for fast protection (less effective than regular feeding)
• Timing: use preventively before forecast cold, or as soon as plants hit a sudden drop - effects are cumulative, so start early
• Stage: suitable throughout vegetative growth and flowering; do not use at the same time as VitaLink Chill
