From Triple Performance
A
Anti-frost candles allow to warm the air at night '''during short and occasional frost periods'''. This provides a '''thermal gain of 2.5°C, for 500 candles per hectare with a usage duration of 11h per candle.''' +
This method consists of competing with the bacteria responsible for vine leaf frost through competition from new species. +
B
The principle of this method is to '''warm the air'''. This allows a '''thermal gain of 5°C''' or more. +
C
The principle is to burn special logs to increase the temperature around the plants by '''2°C'''. +
This method limits the transfer of heat from the soil to the atmosphere during the night as well as the risk of leaf burn by "magnifying glass effect" in the morning. +
E
This substance strengthens the plant's natural defenses by '''lowering its freezing point.''' +
I
Device allowing to '''warm the plant directly without needing to warm the air'''. +
S
The principle of this method is to '''warm the air''' by fuel spraying. A thermal gain of 5°C or more is estimated +
