weed grow box no smell

The impact of air circulation in different phases of plant growth is well known. Proper air circulation keeps the temperature and odor levels low while recycling used CO2 out of the indoor grow space.

Excess odor can be an indicator of a poor growing environment for plants. From the ventilation to air-circulation and temperature, there are a lot of factors that play a key role in cannabis growth and farming.

These should be reserved for emergency situations and it is recommended to use sparingly, as the scent lasts only for a couple of hours and when used excessively, the plants will absorb the scent.

Also, most of these methods are intended for large scale indoor grows. If you’re growing a single plant or only a handful, then the odor won’t be worse than smoking a joint in your living room, and these methods of odor control may be overkill for you.

These solutions, while keeping the odor levels low, also focus on maintaining optimum growth conditions for the plants which are an obvious benefit in the long-term.

It’s not a huge surprise to anyone that cannabis smells. It has a very distinct, pungent, and lingering smell that is widely recognized.

They are recommended to be used in a commercial environment as they can be programmed based on the space of the grow room.

The easiest way to tackle this is to install fans in the grow room.

It is important to remember that as pleasant as growing cannabis is, not everyone shares the same opinion.

Odor control helps keep the smell low and prying eyes away from the grow room.

Both standing and oscillating fans provide varying levels of air circulation that not only keeps the air clean but also removes the odor when paired with an air duct and an exhaust fan.

Use Odor Absorbing Gels.

Whether it is a large personal cannabis grow room or a commercial one, odor control is something that shouldn’t be ignored – especially early on, since it will only get worse.

For someone who is starting or has started an indoor cannabis grow room, the smell can be a huge drawback.

Are there effective ways to control cannabis odor? There are various ways to control weed odor. These include: ensuring proper air circulation, installing an activated carbon filter, use ozone generators, fitting surface and air purifiers, using odor absorbing gels and keeping room temperature in check.

While the smell is tolerable and fleeting on small grows and with single plants, it does tend to get inconvenient for long-term, large scale grow-ops.

While it is easy to ignore odor control, there are several reasons why a large-scale indoor cannabis grow room should be odor-controlled.

Also, using these products on your cannabis plants can reduce or alter their natural smell.

Make sure the “CFM” rating of the carbon filter is the same or slightly higher than the one listed on your fan. This ensures maximum efficiency but also has an added security benefit: it makes sure your carbon filter is only taking in as much air as it can effective scrub for odors.

You don’t even have to attach the fan to anything, you can just let the scrubbed air go back into the room. It’s pretty amazing how fast this can clear up a smelly area! I learned this from a dispensary owner. Here is an example of a fan/carbon filter combo.

With a carbon scrubber, you need to set up a situation where the smelly marijuana air is being forced through the filter. In other words, you need to use a fan to push or (even better) pull air through the carbon filter.

What’s the big deal?

How to Find & Install The Right Carbon Filter.

Have you ever been standing somewhere with no one around, and you catch a hint of marijuana smell in the breeze? Even if you couldn’t spot the source, you wouldn’t doubt what your nose told you.

Well, ignoring the fact that Ozone is not as effective as a carbon filter at reducing odors, one problem is that they’re bad for the environment. So much, in fact, that they’re illegal in the state of CA where I live (see: http://www.arb.ca.gov/research/indoor/o3g-list.htm).

There really aren’t a lot of options when it comes to stopping smells in the grow room. Either you find a way to “scrub” the smells out of the air, or you find a way to cover up the smell.

1.) Identify the diameter of your exhaust.

Recommended 6″ Carbon Filter setup.

I’ve heard of growers using everything from incense to “bathroom sprays” to cologne to try to cover up the smell of a flowering marijuana plant.

Generally, they seem to last at least 4-6 weeks for most growers, which is long enough for a few of these to provide coverage throughout the smelly second half of the flowering stage.

Sprays, Glade Plugins, etc – Generally these are only effective for a few hours at most. Only recommended in an emergency!

Refer to the diagram below to see how a carbon filter should be set up in your exhaust system. The carbon scrubber being placed at the back of the exhaust system minimizes the risk of flowering cannabis smell escaping.

For a larger grow, you will likely need to scrub the air to make sure you’re not leaking any smells that might catch the attention of nosy neighbors.

Unlike a carbon filter, odor neutralizers don’t “scrub” the smells from the air.

Today we’ll quickly get you up to speed the options available to neutralize smells made by your plants, and we’ll explain which methods are most effective.

Carbon filters are…

Ozone generators are sometimes added to grow rooms to neutralize smells. Ozone generators claim to remove odors, clean the air, and kill mold and mildew.

2.) Match up CFM rating between fan and carbon filter.

Example of a carbon filter set up in a grow tent – this device scrubs all smells from the air so odors never leak outside the tent.

But Ona products can reduce or alter the smell of your cannabis buds if they share the same air, so you should never place Ona products in the same area as your flowering plants.

How long do they last? It depends on the size Ona Product you buy, as well as the temperature/humidity of your grow area.

For example, if the carbon filter says “300 CFM”, your fan should be rated as 300 CFM or just a little lower. A 600 CFM fan would pull more air than the 300 CFM filter could deodorize.

Although some growers claim that ozone generators are the best means of eliminating odor, at GrowWeedEasy.com, we strongly recommend against having one in your grow room.

Ona Gel in the original scent seems to be the most effective for covering up marijuana smells in our tests. With a few flowering plants in a grow tent or closet, you will be able to cover up almost all smells with one or two of these placed outside the grow room.

However, there are a few heavy-duty products available that are effective for small-scale marijuana grow rooms.

There are some simple steps involved when installing a suitable carbon filter for your needs. The steps may vary in relation to factors such as the brand of your filter and more. They include.

The simple answer to this question is no, grow tents are not smell proof. Before the room classifies as smell-proof, the grow tent might have to conceal the scent of your flowering plants. While grow tents are unique for various reasons, you have to be cautious if you want to conceal the smell. There are many benefits associated with using a grow room, including temperature regulation, improved lighting, and humidity. Other grow rooms are also available with components such as fans, ventilation systems, and carbon filters, which are ideal for controlling the smell in the grow room.

Thus, consider equipping the grow room with an inline fan or any other suitable system which can clean large amounts of air. The strength of the fan and size of the carbon filter determine the amount of air that can be cleaned at a given time. On average, the carbon sizes should have a 4 to 13-inch diameter. To determine the best suitable carbon filter size, you will have to consider various other factors as well. These include the size of the room and the number of plants in the area.

This applies to every aspect of the planting process. The temperature and humidity level in a given area will significantly increase the scent of flowering plants. Have you ever wondered why collections of trash outdoors tend to smell the worst during the summer months, rather than winter? Well, it’s the same case as a grow room. High humidity and temperature levels, especially during the summer, are likely to increase the marijuana scent.

Left unchecked, the smell of a flowering plant can linger in the air and increase in intensity over time. Factors such as high humidity and temperature are likely to prolong the presence of ascent in the growing area. Thus, the first step to consider is to evaluate the moisture and temperature levels of the room. It’s also important to note that different plant species have as many different germination needs. As your plant’s transition and grow, ensure that you control the vital plant growth factors to provide the best results. You can use resources such as dehumidifiers and air conditioners to solve the issue.

Determine the CFM Rating of your Fan and Filter.

You also have to ensure that the CFM rating on the carbon filter is similar or higher than the one indicated on the fan. This way, you can ensure optimal efficiency when it comes to air ventilation purposes. Using this approach helps to ensure that the filter only cleans a small amount of air at a time. For instance, if you have a filter indicated “300 CFM”, then the fan should also be rated as “300 CFM.”

If you come across an emergency issue where you have to get rid of the smell fast, you can consider the following technique. Place the exhaust fan on the top section of the carbon filter, and the position where the scent is strongest. The best part about this technique is that you don’t have to connect the fan to anything. You just have to let the scrubbed air travel back to the room. Consider investing in a specially made vents for your groom. While this might seem like an additional charge on your project, the overall benefits make it a reasonable solution.

Yes, it’s tough work to hide the smell of your grow room, especially when a flowering plant nears the harvest season. Being able to create an enclosed air space where the smell won’t escape is usually a daunting task.

One of the best methods through which you can eliminate the smell from a grow room would be to use an absorbing gel. The Ona Gel is among the leading brands when it comes to controlling odors in grow rooms. It’s a cost-effective and robust product.

More so, the Ona Gel brand makes various other odor absorbing gels that you can use in your grow room. These gels work by neutralizing the smell in the air, thus reducing the scent of the flowering plants. That said, you have to remember that these gels are sometimes not entirely effective. While they work to a certain extent, if you have a few plants that smell strongly, these gels might not be suitable.

In some cases, you might have grow rooms with three plants, but requires large amounts of absorption gels. Furthermore, the scent of flowering plants is usually very clear, and you might have to use this approach along with other methods.

The best way to apply the gel would be to apply it outside the room. To keep any scents contained, you might have to use the gel along with some air fresheners.

The other thing to think about here is where you are directing the air. As mentioned a couple of times now, your weed plants need air and climate control, so totally sealing up a grow room is out of the question. The primary issue to consider is that the air coming from the room might have a strong marijuana smell.

You can seal the small holes by using sealants and ensure that the doors in the grow room provide an airtight seal. However, air will still come from the grow room regardless of which technique you use to control the problem. Using a combination of resources such as carbon filters, can play a significant role in controlling the ventilation system.

Thus, when it comes to making the grow tent airtight and smell-proof, you can consider this a tough challenge. That said, there are various techniques you can use to reduce the level of odor emanating from the grow room. Usually, these techniques help you to eliminate or redirect the smell in a different direction partially.

What Strengthens the Odor in A Grow Room?

The main benefit of a carbon filter is that it absorbs large amounts of weed while maintaining the composition of the air. That said, even the best carbon filter won’t be able to remove 100% of the smell from your grow room.

Thus, using an ozone generator is a delicate process, and you might have to conduct further research for your needs. There are many different brands of ozone generators, with as many different air capacities. You will have to take all these factors into perspective when buying one for your grow room.

Proper air circulation will help you maintain the temperature, and odor levels in your grow space. Therefore, you can recycle the already used CO2 out of your grow space. Ensuring that the grow space has sufficient air helps you achieve the best ventilation results. Using resources such as high-intensity discharge lights are not suitable for a grow room, because they raise the temperature. Yet, even the smaller lighting systems such as light-emitting diodes and small fluorescents have challenges as well.

Using a carbon filter is a practical approach for controlling the scent of flowering plants in a grow room. Usually, the carbon filter works best when used together with an inline fan. Most carbon filters consist of used blocks, which work to trap carbon and neutralize any scents. Aside from being common for grow rooms, carbon filters are also conventional for various other applications.

Also, you have to consider the ports through which you will direct the air. Any savvy farmer will know that plants require air and climate control to achieve the best development results. Thus, sealing up a grow room completely might not necessarily be a good idea. That said, using a carbon filter, and a well-installed ventilation system will be a good start.

The main reason behind such an occurrence is that plant pots require ventilation, for photosynthesis. Thus, the old air has to get out, as new air comes in, with humidity, and to provide temperature control benefits.

Most of the conventional air-cooled grow lights have sizable 6-inch exhaust holes, which are perfect for ventilation. For most small-scale farmers using tents, you want to use a unique combination of resources such as a fan, ducting, and carbon filter. Why is a 6-inch exhaust hole suitable? Well, the 6-inch fans are powerful enough to direct air from the grow room. Any small-sized fan is usually too weak to redirect the air from the grow room area.

4. Direct Ventilation Exhaust The Right Way & Seal Up Holes.

Broadly speaking, an ozone generator is not suitable for a grow room with poor ventilation. More so, an ozone generator is not ideal for the grow room, especially during the harvest or pruning seasons. Ozone can easily compromise your overall health, and you should consider other solutions to the problem. These include ventilation fans, which you can install at strategic vents in the room. Using ozone generators is also a delicate process, which is states such as California have imposed strict regulations on its use.

The next step is to install the fan and filter into the exhaust system. A fan is important for the ventilation process in the grow room. While there are no specific steps involved in the installation process, you have to ensure that you place the fans and filters in the correct positions. Using this approach will ensure that you install a highly effective resource to clean the air in the grow room.
