Are you curious about the best temperatures for different stages of your plant’s growth? Well, you’ve come to the right place!
Growing plants is becoming increasingly popular. As the legalization of plants continues across North America, plants enthusiasts are increasingly interested in growing their plants. Not only is it an enjoyable hobby and pastime, but it also allows you to grow more affordable plants and perhaps exciting new strains that local dispensaries don’t stock.
One important part of growing plants is controlling the temperature. Too hot, and your plants can die. Too cold, and they can die. It may sound very dramatic, but controlling the temperature inside your grow room is important for achieving a high-quality yield.
In the following article, we’ll take a closer look at how temperature influences your plants and how you can help control temperature.
What Role Do Temperature and Photosynthesis Play?
Photosynthesis is the process by which green plants utilize sunlight to synthesize nutrients from carbon dioxide and water. The process of photosynthesis is positively affected by temperature up to a point. However, if you get your plants too hot, it can start to harm your plant, negatively affecting growth and ultimately can kill your plant.
However, if you don’t give your plants enough heat, it can negatively affect them. They sound like fussy children, but once you get your grow room dialed in, your plants will thrive, and the quality and yield from your plants will be greatly increased.
The Ideal Temperature for Plant Per Growth Stage?
Below we have outlined the best temperatures for the three most important stages of plant growth. This will give you an approximate temperature guideline and help you to monitor your grow room temperatures.
1.Seedlings– The best plant seedling temperatures are between 68-78°F(20-26°C).
2.Vegetative Stage – The best plant vegetative temperatures are between 70-82°F(21-28°C).
3.Flowering Stage – The best flowering plant temperatures are between 65-80°F(18-27°C).
What Happens When the Temperature is Too Hot or Too Cold?
When the temperature inside your grow room gets too cold, your plant’s metabolism slows down. This fall in metabolism can negatively affect the growth rate of your plant and also its buds. As a result, the root system won’t grow or perform like it should, which can leave your plant stunted because it’s not getting enough nutrients for healthy growth.
We like to think that plants love hot environments, but the truth is that too much heat could actually be hurting your plants, not helping them. If your plants are exposed to excessive heat, the plant and leaves can start to change to a yellow color, and leaves can droop or wilt.
When your plant is exposed to excessive heat during the flowering stage, rather than concentrate on growing buds bigger, it can actually grow more buds that are much smaller. This is commonly referred to as fox tailing.
How Can You Control Your Grow Room Temperature?
Too Hot – The lights you use in your grow room generate a certain amount of heat. Too much heat can stress your plants and negatively affect both the quality and the yield. Fortunately, there are some things that you can do to lower the temperature in your grow room.
Too Cold – If your plants are too cold, then it can place undue stress on them and affect them through each stage of growth. Fortunately, there are some things that you can do to increase the temperature of your grow room and make your plants more comfortable.
- During the seedling stage, you can utilize a heat mat to raise the temperature below your seedlings.
- Adding additional insulation can be added to your grow room. Also, consider higher-quality insulation which performs better than cheaper insulation.
- Try growing plant strains that perform better at lower temperatures.
- Keep the roots of the plants evaluated from the cold floor.
- Don’t allow excessive hot air to blow onto your plant, as it can burn the leaves.
As you can see from above, temperature plays a huge role in how well your plants will grow. So if you can identify how hot or cold your grow room is through the different stages of growth, you’ll be able to influence how well your plants grow. More importantly, if something is wrong, you’ll be able to take the right steps to correct it.
