-Harvest staggered in time: It’s an interesting option, because if there were any unforeseen frost, we would not lose the entire crop, and we will have for longer time marijuana ready to harvest, we will be also able to crop in less space than if we were growing all the seeds at the same time. You should use to do it well an indoor germination and maintenance seedlings under indoor contidions.
-Try a greenhouse in the garden: Better an outdoor crop in glass greenhouse. This is the main recommendation to be taken into account when you decide to grow marijuana in winter, as this increases the size of the vegetal mass and is less likely to be invaded by pests. Humidity is also well controlled in this way, as plants are not exposed to the rainfall regime.
For a long time and specifically in countries where it is not particularly cold all year round, as is the case in most European countries, a large number of marijuana growers devote to this task in the less hostile months of the year, i. e. those that range from April-May (germination and transplantation of seedlings and cuttings) to September-October (harvest), approximately, which is the time of outdoor harvest. The rest of the year, they devote to enjoying the production and prepare the next harvests.
The best varieties for cold climates
Therefore, if some of the best seeds are provided from these countries to the current cannabis market, is because is really possible to grow cannabis during the cold season, taking into account that many of the genetics which can be found in the seed market, have been progressively adapted to European latitudes.
Before we get fully into the advice on how to grow cannabis in cold climates, it is important to know that the seeds we grow during this period will not result in large plants, and as a result the production will be smaller, although we know it will be worthwhile.
And in case you don’t dare to do a winter crop, in other posts we will try to work entirely indoor, mentioning the best tips for your indoor crop.
How cold affects marijuana
It is advisable to keep the seedlings indoor until the plant mass is adequate. In case they are cuttings, it is not necessary to take them out immediately, we can make them grow about 30 days. Watch out! As soon as we take our plants outdoor, the most normal thing for them is to start blooming, because they will notice a photoperiod shock.
Actually, the problem is not the cold. It is true that the cold slows everything down, but the important thing is that it is cold, among other things, because the solar radiation is not so intense, and because of the scarce number of sunlight hours (photoperiod).
But did you know there’s a type of cannabis that will make buds even if you leave your grow lights on for 24 hours a day?
Other fluorescent lighting uses very similar technology as CFLs, but the bulbs come in different shapes, some of which can be more suitable for growing. While not as stealthy or small as CFLs, other fluorescent lighting can be a cheap and effective way to nurture young cannabis plants.
Note: Slightly chilly is okay, but never expose your plants to freezing temps!
Why Temperature Matters to YOU As a Grower
7 Essential Concepts About Temperature Control
The following model of heater is an excellent example of the type of heater you want for your grow room – it puts out gentle heat and has a thermostat you can use to have it automatically turn on and off as needed. The heat radiates out instead of being pushed out (which you don’t want in your grow room). It’s almost entirely silent. Plus, it comes with a timer, so you can have it preset to turn on just before lights go off for the night (or whatever you need for your space).
If your grow room feels warm or cold, humid or dry, that is a sign that you may want to look into changing the temperature or humidity of your grow area.
With a properly insulated grow box, your grow lights will likely provide enough heat to keep your cannabis plants warm unless you live in a freezing cold area, or perhaps if you’re in the middle of winter or a cold spell.
Temperature & Humidity Adjustment Cheat Sheet
Some people are growing in a garage or attic that is okay during the day but is getting too cold at night when their grow lights go off.

Also consider humidity. Depending on the stage of growth, pot plants generally like relative humidity from 40% to 70%. Conditions that are too humid can lead to disease, molds and fungus. Extremely dry conditions can retard the growth of your pot plants.
Pot plants need plenty of sun to grow too. But indoors they will be shielded from Old Sol. To substitute for the sun, a wide choice of grow lights is available on the market, making it easy to meet your growing needs and your budget.
You can buy all the parts necessary for a drip system individually and assemble them yourself, but drip irrigation kits offer an easier and more economical option. They give you everything you need and can be assembled in as little as a few hours. By adding an automatic timer, you can even ensure your plants regular watering when you are away.
Whether you want to raise cannabis commercially for profit or are looking to grow some bud for recreational fun or medical marijuana for good health, setting up and using a grow room offers lots of advantages. Unlike growing marijuana outdoors, raising it indoors in a grow room allows you to control all the crucial conditions that affect its growth, like temperature, light, nutrients and water. In addition, growing weed indoors will keep it away from destructive four-legged pests like rabbits and deer who may want your crop.
How to Get Sunlight & Fertilizer for Indoor Cannabis Plants
In addition to high summer temps outside, grow lights themselves can cause excessive heat. If you are battling high heat, look for lights that emit less heat. In addition, you can use fans or portable air conditioners to cool your grow room to the proper temperature.
To help you get the most out of your pot-growing efforts, DripWorks has put together some basic tips to help you achieve the ideal grow room conditions for growing cannabis indoors. Whether you are growing one marijuana plant or a thousand, these ideas for perfect grow room conditions should help you get the most out of your efforts.
If you need to increase the temperature, you can use a variety of traditional heating options, including electric, gas and other sorts of heaters typically used in homes or commercial buildings. Heat lamps and insulation are other possibilities, while heat mats underneath containers can warm the soil. In larger spaces, a fan can help circulate warm air so all plants can benefit from it equally.
Just like people, plants do their best in a particular temperature range. Generally, pot plants in their vegetative stage prefer a temperature in a range from about 68 to about 77 degrees Fahrenheit. When they are flowering, cannabis plants like a range of about 65 to 85 degrees Fahrenheit. They can live in lower and higher temperature, but since you can control the heat simply indoors, why not give them what they want for maximum growth and potency?
Water is a crucial element of life, and pot plants are no exception. They need adequate amounts to thrive. Growing plants inside, you will need to provide a steady supply of just the right amount of H2O. You could hand-water with a hose or a bucket, but that is a time-consuming and inefficient process. A good drip irrigation system can deliver just the right amount of water to each of your plants efficiently and reliably.
