As temperatures drop, it’s time to start thinking about how you’ll keep your grow room, and more importantly your plants, warm this winter. A cold snap can seriously damage and at times even kill your plants. Prepare your grow room and your setup, and you’ll minimise the negative side effects of winter chills.

Monitor Temperatures

While your lights are on, you should be ideally looking to keep your room temperature between 25°C - 28°C, falling to a range of 18°C-21°C while your lights are off. When thinking about your room temperature, consider setting your "Lights On" period for during the night, when the room will naturally be the coolest, and your "Lights Off" period for during the day.

You should always keep a keen eye on the temperatures your grow room is reaching so you can act accordingly, but in the winter it's more important than ever. Installing a classic wall-mounted analogue thermometer (also available with a push button min/max option) is a cheap and easy way of giving yourself that constant reminder.

Taking cuttings is one of the most rewarding and in a lot of cases the easiest activity you can do in the grow room.

The ability to create multiple plants from one single variety is an incredibly useful tool to either preserve genetics or create large numbers of plants, all of the exact same genetic material. 

Cultivating clones of the same variety (mono-crop) is the best way to generate high yields with the greatest ease. As the plants you have created are all from the same genetic material they will all have the same preferences in regards to environment, nutrition and pH levels, as well as all having the same structure and height. Growing plants from seed is always exciting. 

Seeing, smelling and feeling the differences between each plant is very interesting but as plants vary in appearance so do their environmental and nutritional preferences. Growing for yield from seed is a challenging task as it is much of a guessing game to give your plants exactly what they require as every plant will have different preferences.

Pictured below are cuttings taken from a Lemon Scented Geranium. These plants do not require a propagator like most other plants that have glabrous (smooth, not hairy) leaf surfaces. Geranium plants have a fine covering of short erect hairs that trap moisture around the leaf surface that minimises water loss through transpiration. Plants that have a glabrous leaf surface require a propagator to create a humid environment to minimise water loss and prevent wilting.
