What we liked most about this option is that it gives users the benefit of using red and blue tones in their bulbs, but none of eerie purple glow.

The box of this unit is black, which is different from all of the white cases we have seen from other brands out the on the market.

9. Mars Hydro
Easy to hang
Small and compact box
What makes this design different than all of the other is that it has a reflector panel on the front of the unit that will magnify and strengthen the spectrum of rays given off by this small and compact little unit.

Criteria Used for Evaluation
If they aren’t very effective, then what you have on your hands is a very strange ambient lamp.
So, how did we determine how effective these products were? There were three main components that we took into consideration. The first feature was the bulb itself. Fluorescent bulbs have a reputation of being real energy hogs, but they are also incredibly powerful. We made sure to select at least one option with a fluorescent option, because some indoor gardeners feel they are the most effective for their plants. However, LED options seems to be the markets favorite choice by users for a myriad of reasons. The first reason these units are preferred is because they are easy on energy bills, and for the environment. Plus, they are known to last quite a bit longer than HID options. While wattage was something that we kept in mind, the most important thing we looked at was the type of brightness and the tone of the bulbs. Products that had a wider spectrum of color that ranged from UV and blues to IR and reds were generally considered to be more effective than those that simply offers a small fraction of the color scale.
Size was important to us because it determined how much floor space the bulbs could cover, and in essence it means how many plants will be able to be serviced with one single unit.
What we discovered is that products that used LED models and that carried a reasonable price tag typically measured to be about 12 inches by 12 inches, with subtle variances in depth depending upon the presence of a cooling fan. If you are in the market for a product that is going to be able to cover a lot of ground in your home, you might want to purchase a fluorescent designs, because they are typically bigger than LED options, and come in at a price point that is a little bit lower. However, if you want the benefit of LEDs for your larger space, be sure to select a style that has the option to daisy chain multiple units together using one centralized power source. Many of the options out there on the market has this feature built in on the side, but there are a few out there that don’t. Before you make your purchase, be sure to measure your room and determine how many feet of coverage you will need for your indoor plants.
Sure, you want your plants to get all of the nutrients that they would get from the sun, but you also don’t want your house to suddenly look like a 1980’s fraternity.
When we conducted our research, we made sure to include designs that were more neutral and had white and yellow tones to blend in with the neutral motif of your living room. For many, these lamps will be housed in their basement or attached garage, so a little bit of groovy purple infrared lighting will not be as much of an issue. We also wanted to select styles that were housed in basic and neutral aluminum or plastic frames. One factor that users will need to consider is the option of a cooling fan. These fans are great and keeping the bulbs cool and the plants below from getting burned, but we discovered is that they can be rather loud. If you plan on placing one of these units in a high trafficked and lived in area of your home, you might want to forgo the inclusion of the fan all together, or be sure to select a design that users have claimed that the fan is virtually silent, such as the AGLEX option. Again, for users that are buying these products for a basement or garage, this probably won’t be much of a issue that you will need to consider.
How these units are used and mounted in your home is an important aspect that we took into consideration.
We tried to stick with designs that were able to be used in more than one way, such as mounted from the ceiling or propped up on its side either vertically or horizontally. Finding just the right angle to place these products is a really important part of the process, so we wanted to make sure that were selected options that were able to be used in a myriad of ways. One thing that is important to keep a lookout for in the inclusion of mounting hardware that is included with purchase. No one want to make a trip down to the hardware store to buy special wire and hooks to mount their unit just right- you want anything to be included with purchase. Another thing that is important to consider is the ability to daisy chain them together. This means that you want there to be an input plug on the base of the unit so that you will be able to plug in more than one unit on a single power source as your indoor garden continues to grow.
No one wants to spend more money than that need to, which is why we selected some designs that will keep costs at a minimum.
What we discovered is that there are two separate price points that these units reside. One price point is affordable and will likely set you back the same amount that you would spend on a pepperoni pizza. For these models, they typically didn’t have the same amount of power as some of the higher end designs, although they still offered the same range of red and blue light. The only difference in the lower end models were that they typically were not as powerful, and they also didn’t come with the addition of a cooling fan in most cases. If you really want to ensure that your plants are taken case of and will get enough nutrients from their light source, you may want to dish out a little bit of extra money for some of the higher end options.
Expert Interviews & Opinions
The most important thing that users need to look at when considering these models is the type of bulb that is used. Many contemporary indoor gardeners prefer the use of LED because they are easier on the environment, easier on your electric bill, and do no generate too much heat that may negatively affect your leafy growth.
Size goes hand in hand with cost. You aren't going to want to purchase something that it going to be more than you need, because that means that you are spending money on something that isn't the right size for you. Be sure to look at the coverage area of each option to ensure that it matches the space in your home that you will be using it.
Cost can sometimes be an issue, because some of the higher end models pack a wallop of a price tag. We suggest that if you are new to gardening indoors, it may be in your best interest to opt for one of the more affordable and less powerful options to see how your fare before spending money on one of the more expensive options.
Frequently Asked Questions
If you want to make sure that your crops that you are going to plant in your garden this summer are going to be plentiful, you might want to get a head start on the growing process. While many gardeners plant their seeds in the ground in the late spring, it can sometimes feel that it may take an entire growing season for your crops to even start to bloom, and an early frost in early fall can mark the end of your entire season. Many like to get a head start on growing their crop inside while there is snow on the ground. Using one of these products, gardeners can grow their seeds until they are big enough (and it is warm enough outside) to officially plant them and essentially extend their harvest. Others just like the idea of looking at beautiful flowering plants all year round, and these products make that possible.
This is a popular question, because different shades on the color spectrum product different effects. The natural color spectrum starts with UV rays, then blends to cooler hues, meets in the middle for yellow and whites, then moves on to warmer hues such as red and orange, and ends with infrared. Generally, warmer shades such as reds, oranges, yellows and and IR rays are preferred for initial growth for seedlings and younger plants. Cooler hues such as blues, greens, and UV rays are ideal for leafy growth and stem health. Most products out there on the market have a blend of both shades so they will be ideal for everything. Some of the higher end models allow users to adjust the coolness or warmth of their bulbs to focus on one specific stage of their plants growth. If you are serious about your indoor garden and want to see quick results, you may want to spend the extra money and opt for a design that will allow you to adjust the tone of your bulbs.
In the case of fluorescent bulbs, this is a real possibility. Due to this fact, almost all designs that you see out there on the market that utilize the fluorescent options also have a series of fans built into the base to keep the heat to a minimum. Some novices may assume that the reasoning for using these products is to reproduce the heat from the sun, but this isn’t the case at all. The reason why these bulbs are so important is because they produce the much needed rays (such as UV and IR) that are emitted from natural sunlight to synthesise their food. Typically, your home is already at the right temperature for your indoor plants to thrive. It is the rays emitted from the bulbs that they need to survive in the lowlight of the winter. What we found is that LED options are a great source of these types of rays, and they don’t produce the same amount of heat or use as much energy as fluorescent bulbs. Some users have found that even when their crops are actually touching their LED bulb, they still don’t burn from the low level of heat.
The answer to this question lies solely in who you ask. Many old school home gardeners swear by their fluorescent bulbs because they are the best at generating a lot of power, and they feel that the LED lights just aren’t strong enough to emit the same level of beneficial rays. Also, many LED options do not emit any UV or IR light at all- which may slightly stunt your plants growth. From our research, we found that the benefits of the LEDs are outweigh the few benefits of fluorescent or HID bulbs. The most important benefit of LED designs is that they don’t require a great deal of power to function, which translates to money saved on your energy bill. This also means that they aren’t going to run as hot, which is going to be beneficial in keeping your plants from becoming too hot as they grow closer to the base. LEDs have a much longer lifespan than the traditional HID bulbs, and they also run silently and don’t give off that iconic hum that users may recognize.
It can be a little unsettling leaving for work in the morning and not turning off all of the lights before you leave. However, if you are sure to follow a few simple guidelines, there is not reason that you cannot leave the house for the day with your lights on and feel perfectly comfortable in doing so. The very first thing that you are going to need to look at before you make your purchase is to ensure that your product is CSA or UL approved. Another important task is to ensure that you read the safety instructions booklet in its entirety before use. When you hang your unit, be sure that you never overload a wall outlet, or place wires in places where moisture can occur. If you follow all of the precautions listed here as well as on your products label, these units are perfectly safe to use, even if you are not at home while they are in use.
