11. Amazon Basics Ceramic Mini Heater
One problem that a lot of people have when choosing a heater for their grow tent is that it is hard to know if it will be too strong for a grow tent. This is where the Amazon Basics ceramic mini heater comes in – this is an ideal product for grow tents ranging between 2.5 x 2.5 to 4 x 4 ft. This product, coming from the house of Amazon, ensures that your plants get enough heat, but also ensures that it doesn’t end up overheating the tent and damaging the plants. This is a heater that is meant for small places and is well-suited to be kept on small tabletops while working.
The heater functions by heating up the ceramic coils present inside it. Once the coils heat up, they emit enough heat to warm up the area around the heater. Do note that this is not a forced-air heater. Those are heaters which blow out hot air from the inside. This is a ceramic-based heater which heats up the coils inside it and the warmth is then spread across the tent, giving it a more natural vibe, and helping the plants warm up better in cold seasons.
For anyone still wondering about the size of the heater, it measures only about 16 cm (6.3 inches) in height. Operating it is fairly simple as well, you simply have to plug it in and press the one switch that is placed on the back. Another interesting thing about the design of this Amazon Basics heater is that it comes with a ‘tip over protection’ which ensures that you have a sturdy base and the heater doesn’t just topple over. It remains firmly placed on the surface that you decide to keep it.
Being a convection heater and not one which blows air, you get one more advantage here – it operates very silently. There is absolutely no noise and the heater helps you warm up your grow tent rather silently. Lastly, there’s the obvious price advantage – heaters can be an expensive affair but since this is an Amazon Basics product, it is actually priced quite low as it delivers just the basic feature of heating up a space without any extra bells and whistles. At a price of about $20, this is totally worth the money. You might even want to buy multiple units to provide additional warmth to your plants in some very cold weeks.
- Compact and can be carried around with ease and kept anywhere
- Works in absolute silence
- Great for heating small spaces without overheating them
- Comes with a sturdy base and offers a ‘tip over protection’
- Might not be the right kind of product regions that tend to be extremely cold.
Ultimate Buyer’s Guide
When it comes to buying a quality grow room heater, there are a few important factors that need to be considered. Choosing the right grow heater is crucial for the growth of your plants. You should also remember that plants are more sensitive to temperature changes than humans. Even the slightest rise or drop in the overall temperature can be easily detected by plants. Therefore, you need to be very particular with your choice.
You will find this buyer’s guide helpful if you have less or no idea about buying grow tent heaters. The most important factors you need to look for are:
The first thing you need to check is the size of the room. Grow heaters are available in different sizes, which are suitable for rooms of varying sizes. The size of the heater determines the amount of heat it produces.
If you have a large grow tent, you will require more heat. This means you will need to choose a bigger grow heater. It will produce a lot of heat and distribute it nicely in all corners of the tent. In case, your grow room is small, you can get a less powerful or smaller heater. The grow room size plays an important role in choosing the size of the heater.
Type of Heat
You also need to pay attention to the type of heat you are providing your plants. Depending on the type of heat, it can either be good or bad for your plants.
If your grow heater generates infrared heat, it is harmful to the plants. So before you set to buy out a new grow heater, you must consider the type of heat it is producing. You must also check whether it is an oil-powered heater or using a fan to circulate the air in the tent.
Type of Heater
Before buying a grow heater, you must know the types. There are two types of grow heaters. One is oil-filled heaters and the second is ceramic heaters.
The latter uses a ceramic heat stone to produce heat, whereas the former needs oil to function. If you want more heat, ceramic heaters make a better choice than oil-filled ones. These heaters also have fans to disperse the heat.
The more energy a heater consumes the more heat it generates. However, it is not always true. Before you get a grow tent heater home, you must check the amount of energy it consumes.
To put it straight, you need a grow heater that generates enough heat for all your plants. But at the same time, it should consume less power. If a grow heater consumes too much energy, it will spike the electric bills. Luckily, there exist many energy-efficient models in the market.
When buying a grow heater, you must also look into the safety factor. Before investing in a heater make sure it is safe to use. This is crucial to prevent any accidents from occurring.
A safe grow heater will have features like anti-tipping and overheat cut-off. These grow heaters are designed to stop working until the condition returns to normal.
Ease of Use
The next important factor is ease of use. Since you are spending your hard-earned money to buy a grow heater, it should be at least easy to use. You should get a grow heater that is easy to use and install. After all, you wouldn’t want to fiddle with the heater for a long time.
Look for a grow heater that comes with temperature settings, so that you don’t have to guess the operation mode. Some modern grow heaters are also equipped with a display screen that shows the current temperature settings. These types of heaters are more convenient to use.
As already mentioned once, you must pick a grow heater based on the size of your room. For a small grow room, a small grow heater is enough. In this case, you should look for a heater that is more portable. Also, it should be able to fit in a small space.
Some of the modern grow heaters can also be hung or mounted. This type of heater is built to save space in the grow room.
1. What are the types of heaters for grow tents?
Generally, there are a few important types of grow tent heaters including the electric heater, the hydroponic heater, oil-filled heater, ceramic heater, and the duct fan heater. Depending on the requirements of the user, the specifications change. You can pick out the one that best works for your grow tent settings.
2. What is the best grow tent heater for cannabis growth?
If you are growing cannabis inside, there are a few important factors that you need to look out for when buying the grow tent heater. Choosing one between 300-400 watts of power is considered ideal for them. As for the type, try and stick around with the electric heaters instead of the oil-filled heaters for the same.
3. Can the normal room heaters be used for grow tents?
Yes, the normal room heaters can be used in the grow tents. Just ensure that you get the ones with adjustable heat settings for smoother functions because that again is very important.
4. Do I need a heater even if I live in a hot place?
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.
7. Where to buy the best heaters for grow tents?
Heaters for grow tents are essentially small-sized heaters. You can find them at most stores that sell consumer electronics, or you can find them at stores that sell gardening equipment. You can even find them at multi-brand retail outlets where electronic items are sold. However, instead of going store to store in search of the best heaters for grow tents, we’d recommend hitting the Amazon web store and choosing from a large number of options that you can find here. Amazon generally tends to give better discounts too when compared with regular stores. Amazon’s return and replacement policies are also much better. For your ease, all the products we have curated are listed along with their Amazon links.
8. How much do heaters for grow tents usually cost?
Heaters for grow tents don’t really come across a wide range. Since you are buying portable heaters for this, you can find most of the electric portable heaters priced in at $70 to $120 price range, with the 90s and the 100s dominating a majority of them. 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.
9. What factors other than heat should I consider while growing marijuana plants?
While heat is an important factor, you also need to consider a number of other things. Most importantly, you’ve got to get the lighting right, especially if you are growing weed indoors. You also need to ensure you are providing the right kind of nutrition to your plants. In addition to that, you need to provide them the right kind of a grow tent when you are growing them indoors. Humidity is another factor to be taken care of. In case you are growing them in a place that is too hot, you might just want to add some additional cooling devices such as clip-on fans and mini air conditioners. 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. You’ve got to keep the temperatures ideal and not HOT. You also need to operate these heaters rather carefully and ensure they don’t end up becoming a fire hazard. You also need to check the amount of electricity your heater consumes so that you don’t end up paying an exorbitant electricity bill.
Getting a good quality to grow tent heater is extremely important if you want the best results for you to grow tent. For the most part, these grow tents are dependent on optimal temperatures inside the tent to ensure faster growth of the plants. Before making the final purchase, make sure that you keep an eye out for the quality of the product, especially with the features and functions. Additionally, check which type of heater would ideally fit the requirements of your grow tent before making the purchase.
