The Best Carbon Filter May not Be the Lowest in Price
Homesteaders must make the right decisions at every step. While you can spend good money on carbon filters of different sizes, shapes, and designs, you should do your homework before purchasing from Amazon. In fact, you could end up with a cheaper option that beats most of the expensive products out there.
Now, bearing in mind the extra care that indoor plants need, it is imperative to compare the available options carefully when shopping for the best product. During this time, many questions will be racing through your mind because you want to avoid making mistakes.
Mistakes that might result in stunted growth or yellowing of plants are always a farmer’s biggest fear. With the failure to produce healthy plants, most farmers take it personally and feel like a total failure.
Yellow leaves could mean some things are not right in your garden. Although It could be due to hydrogen deficiency, there are so many other details farmers need to understand. It can also say there are more pressing problems in a hydroponics farm or aerogardens.
As a farmer, it is therefore up to you to find out what it might be before executing the right solution sooner than later.
Problems That Could Be Going Wrong With Your Plants
The following questions should thus act as your checklist:
Is there a fault in the watering system?
Hydroponics watering system operates in a recirculation manner. Thus, a stagnant culture solution can cause the buildup of acids and other elements such as temperature to toxic levels. Check the pipes, air stones, and pumps from time to time. Making sure no faults are interfering with recirculation is essential.
Are my plants absorbing enough nutrients from a culture solution?
A weak mixture of nutrients or when they are used up can spell doom for your aerogarden veggies and fruits. Most of the products you will buy from agro shops or online stores such as Amazon come with instructions on how to mix nutrient portions, so it is essential to read this information carefully.
Is humidity level optimal?
A grow tent should have proper ventilation to let in enough moisture and also release excess from inside the groom’s room. While some shelters come fitted with air vents, in others, it is you to create this vital feature.
Did I install the best grow tents?
Grow tents function like greenhouses, and there are many of them on the market. You must, therefore, take a look at the best home gardening reviews before making a final buy decision. In case you already installed poor-quality grow tents, you can always do an overhaul and replace them with the best.
Are the carbon filters doing their work correctly?
If a plant wilts and dies, many questions will go unanswered. If you want to avoid such an occurrence, it is crucial to offset grow tents with the right conditions. It should include installing carbon filters and setting up your farm in a conductive area. Always replace old and obsolete filters with new ones.

1, By design, carbon filters are for removing lousy smell/odor in and around groom’s room. You may want to ask; from where does the smell come?

That is when you know a carbon filter is essential. It works by absorbing the bad smell in and around your farm. The cleaners contain Virgin Charcoal (Carbon), which is a very good absorbent.

How to Set up the Carbon Filter
Indoor gardeners always ask; how do I set up my carbon filter so that it serves its purpose of removing odor and impurities effectively? The truth is, the buildup of the smell inside a grow tent can be nauseating. Wrongly set carbon filters to make it even worse.
Some of the things you need to do so that you make the most of yours include:
- A set of fans depending on the size of your grow tent
- A carbon filter through which air will pass. It is essential to make sure what you buy contains activated carbon/charcoal
- A ducting with the ideal length
- Jointers
- Assembling the cleaner
You need enough space that is free of clutter to do the following:
- Wire up the grow fans and confirm they are working
- Identify the exhaust units on the fan
- Now, attach your carbon filter to the intake side. It is essential because it helps remove impurities before they can reach the fan’s housing unit.
The next step is to fix the ducting on the fan’s exhaust end by following these steps:
- You may want to support the group using ropes. If that is the case, there are many good ones on the market specially made for this purpose such as Exolux Rope Ratchet.
- Fix a strong chain to the grow tent’s ceiling hanging bars or plates and then tie the fan and filter to it using a Rope Ratchet to enhance the strength of the support system.
- The hanging height is a decision you would want to make on your own.
