No, if the temperature of your grow tent or your grow room is already at an ideal level or a couple of degrees here or there, you don’t really need a heater then. If you live in a hot place, chances are that you might end up needing an air conditioner rather than getting a heater. A heater is meant only for those growers who are growing their plants in places where the climatic conditions are rather cold, or for those people who are growing their plants during the winter season. Canadian winters, for instance, are a great example of this – with months of snowfall and temperatures that remain well below 0C, you do need a heater for your plants to thrive. Otherwise, they will wilt away in the cold.

5. What humidity needs do I need to take care of in a grow tent?

Plants need not only the right levels of heat but also humidity. Normally, during the early phase of growth, having somewhere between 55 to 60% humidity levels is great for the plants and during the flowering phase, this needs to be lowered to about 40 to 45%. However, different strains have their specific needs so keep an eye out for that. Given that plants need less nutrients during the early phases, it is better for them to take up more water from the moisture. However, reducing humidity ensures that more water goes in via the roots and nutrients are provided along with water, hence reducing the humidity levels helps increase the nutrient intake of the plants during flowering. 

6. Can I grow cannabis plants without a heater?

Yes, you can grow a cannabis plant without using a heater, especially if you are living in a place which has ideal weather conditions. Marijuana plants thrive between temperatures that range between 15 to 28 degrees, with a couple of degrees here or there as an exception. Heaters, however, become essential when you are living in a place which is way more colder than the acceptable minimums. If the temperature of where you’re living tends to be under 10 degrees for long parts of the day, you will need to heat up your grow tents to ensure that your plants don’t freeze away and wilt off.

You can even find them at multi-brand retail outlets where electronic items are sold.

However, there are some heaters such as ceramic-heaters that don’t come with blowers but instead radiate heat by heating up the ceramic body are available for a cheaper price point, usually between $20 to $40. However, electric heaters with blowers are usually more effective when it comes to increasing the temperature of your grow tent during winter months of bitter cold.

These are some of the factors that need to be kept in mind while growing marijuana plants. 

10. How much heat do marijuana plants need?

One of the most important things that one needs to understand is that marijuana plants don’t really need ‘heat’ to grow, but they need a temperature that does not freeze them do death. This is why you will notice that most people who are buying heaters for growing marijuana plants are buying them only because they are living in places that are extremely cold. Marijuana plants require a temperature between 68 to 77 degrees Fahrenheit during the vegetative phase of growth. A temperature of about 65 to 85 degrees Fahrenheit is ideal for the flowering phase. These are the levels you need to maintain if you live in a place which tends to have rather low temperatures. 

11. What are some things I need to keep in mind before buying a heater for a grow tent?

Before you buy a heater, you need to keep in mind the fact that you only need it if the temperature in your city goes way below the required temperatures of the marijuana plant. Know that heat is detrimental to the plant if provided in excess. Anything above 90F in flowering and above 85F in vegetative phase is going to have a negative impact.
