1: IR is used when the grower decides to switch the plant from the vegetable stage to the flowering stage, Turn on IR for half an hour before turning off the lights everyday until see the buds appear,and stop using IR.
2: UV is recommended to turn on in the last two weeks of flowering stage Tum on the UV switch for 15 minutes,then tum off the UV for 45 minutes,circulate like this.the total time of UV on every day is no more than 2 hours in the last two weeks of flowering stage.
(Many plants will use UV and IR at the same time during the vegetative period. Using UV can increase the content of THC. Using IR can increase the photosynthetic efficiency (Emerson effect) of plants and promote growth, so generally experienced growers will use them at the same time!If you are planting for the first time, please follow the steps above! )
