VitaLink Heat — Cold-Weather Plant Bio-Stimulant

VitaLink Heat — Bio-Stimulant for Cold-Weather Growing Below 5°C

VitaLink Heat is a bio-stimulant developed to help plants not just cope but thrive in cold conditions — even when temperatures drop below 5°C. Encourages growth hormone production despite low temperatures. Has also been known to work in frosty conditions, working similarly to anti-freeze for cars: prevents the cellular freezing damage that low temperatures cause. The grow-room insurance for UK winter outbuildings, garages, and cold spaces.

Why growers choose VitaLink Heat:

• Plants thrive below 5°C — not just survive, actively grow in cold conditions
• Encourages growth hormone production — overrides cold-induced growth pauses
• Anti-freeze-like cellular protection — prevents cold-induced cellular damage
• Works in frosty conditions — not just cool, actually freezing
• UK winter grow-room insurance — for garages, outbuildings, conservatories
• Bio-stimulant approach — biological signals, not aggressive chemistry
• Use throughout cold periods — sustained protection while temperatures stay low

Who it's not for:

For warm grow rooms (heated above 18°C), Heat isn't necessary — save for cold-spell use. An additive, not a base nutrient — use alongside a full feeding programme. For active heating (not just plant tolerance), use a tube heater (Grow Gadgets) or oil-filled radiator (Ora 1000W). Pair with VitaLink Chill if you also experience hot conditions in summer; many UK grow rooms swing between both extremes.
