Temperature Problems And Marijuana Plants
Marijuana plants function the best when their surroundings maintain a consistent temperature between 70 and 75 degrees Fahrenheit during the daytime, and 50 and 60 degrees Fahrenheit at night. This ideal temperature can sometimes vary, however, such as when growers add carbon dioxide to their plants, then the best temperature is right below 85 degrees Fahrenheit.
Anything below 60 degrees Fahrenheit is going to cause problems for your marijuana plants – especially if it continues too long and if it’s during the plant’s flowering phase. This can cause problems with your resulting harvest, so it’s important to pay close attention to the temperature surrounding your plants.
With outdoors growing, you should know that they most likely will experience a night or two of as low as 50-degree temperatures. Do not fear: this should not cause long term problems for your plant and its harvest. Marijuana plants are impressively robust, but of course it is still a good idea to keep the environment within the ideal temperature range whenever possible. That being said, if the temperature gets lower than 40 degrees Fahrenheit, there will be trouble for your plant.
Cold temperatures generally cause things to slow down. Your marijuana plants won’t produce yields that are as high as normal due to the delayed growth, although you may not recognize this if it is your first season with this particular plant.
Cold Problems in your Cannabis Grow
When dealing with too much cold, there are some specific steps you can take to deal with its effects on marijuana plants. These methods can vary for indoor and outdoor growing areas. If you are an outdoor grower, you could give a gas patio heater a try. This is especially useful for the night when temperatures are even colder. You should aim for a consistent temperature of 60 degrees, so get as close to that as you can. Another option for outdoor growers is to cover them to provide insulation – try one made out of polyethylene plastic. If you grow in containers you can place them inside during rea.ly cold nights.
If you are growing indoors, try a CO2 generator or electric heater to help balance things out. For big indoor setups, go for a hot water heater that recirculates the water throughout the garden. And make sure to download my free marijuana grow bible at this link here for more growing tips.
Heat Problems in your Cannabis Grow
The cold is not the only thing that might have adverse effects on your marijuana plants – the heat can be just as troublesome. Plants that are overheating will show the earliest signs in their leaves with curling or burnt appearances.
Your plants should not have too much trouble with random bouts of heat if they are mature and have developed sizable root systems, therefore allowing them to take in more water despite the heat. If temperatures are somewhere between 80 and 90 degrees and your plants are in their vegetative state, however, you might see the development of stems that are longer and leaner than normal.

If you are growing your plants indoors and the grow lights are causing the temperature to be too high, then during the flowering phase, buds that are highest (or closest to the light) will be bleached and stretched out. Your plants will have burnt tips as well, but the problem with the buds is the best way to see that it’s an issue with excess heat, not light. Other signs include yellowing, brown spots, and curling leaves. Plants that aren’t receiving enough water have a higher chance of succumbing to heat stress.

How To Fix Heat Problems
To keep things cool indoors, you can install a ventilation fan as well as air conditioning, or else air or water-cooled lights to ensure a lower temperature despite the light intensity. Only focus on the heat that is touching your plants, since that is the only thing that will have an effect on your plants. Exhaust fans work well to dump the heat from your garden outside – just be sure to use a carbon scrubber to make sure the smell of your garden is not launched outside with the hot air.
One simple way to fix the problem is to move the light further away from the plants. Loon-watt lights are supposed to be three feet away from your plant, air-cooled lights should be between 18 and 24 inches from your plants, and water-cooled lights can be the closest: within a foot away from your plants. If you are growing outdoors and there is a heat spell, there are a number of ways to go about cooling down your marijuana plants. For instance, micro-sprayers are a good way to have significant reductions in heat – they could lower the temperature on your plants by as much as 30 degrees Fahrenheit.

If your plants are growing in containers, heat will have a more devastating effect on them. Try moving the plants out of direct sunlight to help combat excessive heat; otherwise, put them into a lighter-colored container instead because it will reflect sunlight.
To prevent heat stress from the beginning, shift your watering times to before and after the hottest part of the day – early morning and late evening, for example. This will allow your plants to absorb the water without it evaporating quickly. If need be, you can cover up your garden with a sheet in order to provide them with shade – but don’t make this a long term change, or else it will cause them to go into shock from the sun when the cover is removed.
For marijuana plants healing from heat stress, try using seaweed kelp extract to ensure that they do return to their former strength. It also serves as a preventative measure and will help keep your plants from getting heat stress again in the future.
Marijuana seeds 80 degree heat
For growers looking to get started with a high-value, high-yield, and highly rewarding grow, cannabis will likely be the big trend in years to come. That’s because laws and attitudes toward cannabis have been in flux for years now, and with greater acceptance comes a new avenue for growers to succeed and find profitability. Combine this with the ideal conditions of a cannabis greenhouse and you’ve got a powerful money maker contained in one easy location.
Growing cannabis in a greenhouse is an excellent way for growers to produce maximum yields, create an extremely high-quality product, and secure against theft or interlopers without cutting off access to the benefits of growing outdoors.
For both experienced and brand-new cannabis growers, a cannabis greenhouse offers the chance to provide cannabis plants with the ideal environment to produce the perfect grow. Here’s a look at just what a greenhouse can bring to your cannabis crops:
Ideal Temperature Control for your Cannabis
Take a minute to think about where cannabis comes from originally – Central Asia and the Indian subcontinent. It’s warm there, and relatively dry year round, but on average temperatures are mild.
These are the conditions cannabis originally evolved to take advantage of, and even through all the centuries of cultivation elsewhere the plant has always retained this taste for a warm, dry growing spot.
Typically, growers should aim to keep their cannabis greenhouses around 70 to 80 degrees – not too hot, but warm enough to keep your plants happy. Typically, the heat provided by the sun through your greenhouse covering – combined with the natural heat given off by the plants as a result of the greenhouse effect – should be plenty to keep your plants warm during cold weather.
In extremely cold locations, it might be advisable to equip your cannabis greenhouse with an excellent greenhouse heating system, which can carefully control your greenhouse’s interior and raise the heat as needed. Likewise, proper cooling and ventilation can be critical to preventing heat buildup during the warmer months. Determine your needs based on the climate in your location and plan your grow space accordingly – your plants will thank you for it.
Humidity Controls in an Artificial Indoor Grow Room
Those who choose to grow cannabis without the protection of a greenhouse may luck out on temperature, since plenty of plants manage to thrive and survive unprotected in the open air. But when it comes to produced the best cannabis possible, there’s one critical element that’s arguably just as important and significantly harder to control: humidity.
Keeping your cannabis plants at the proper level of humidity isn’t just a good way to ensure your plants don’t dry out in the heat – it may also be your best defense against crop-killing mold. Cannabis grows dense flowers, which can absorb a lot of moisture if kept in a too-humid environment and may get diseased over in a matter of weeks. Keeping your plants at that right balance of arid and humid is key to keeping your plants safe through the seasons.
Typically, young plants and seedlings tend to react better to slightly more moist environments – around 60 to 70 percent is right. As the plant matures, it’s best to slightly dial down the humidity, shooting for around 40 percent by the time your plants are fully flowered (around week nine).
Those growers looking for an easy way to control humidity levels in a cannabis greenhouse should consider automatic environmental controls, which can automatically measure moisture levels and vent or dehumidify as needed. This way, you can set the optimal humidity level and let your greenhouse take care of the rest – easy, fast, and simple, and all for better harvests.
Safety For Your Cannabis Crop
So you’ve set your greenhouse to provide the ideal growing environment, you’ve spaced your plants out perfectly to give them plenty of room, and you’re on top of your growing and trimming schedule. Everything is growing great with your cannabis grow – until one day you walk out to your field to find all your hard work has been heisted.
Obviously, cannabis is still a highly valuable crop, and it would be remiss to ignore the need for security when dealing with a cannabis grow. This very present need has driven many growers underground, literally – trading the benefits of fresh air and sunlight for the security of walls and a locked door. With a secure cannabis greenhouse, you can say goodbye to those kinds of concessions.
Secure cannabis greenhouses offer a wide range of security features, from basic camouflaging – like black-out of end walls and blackout curtains including light traps, which can also improve light efficiency – to advanced security with higher side walls, lockable doors, and other accessories to secure the roof and walls.
