When many people think about farming and agriculture, massive corn fields are what come to mind here in USA. I am sure that is different depending on where in the world you are located but the same idea. HUGE OUTDOOR FIELDS is what comes to mind. 

But today we are talking about Many Different types of Indoor Growing Environments. Many people see Indoor Growing as a way of the future. But due to its higher entry cost, it is less common. This is changing as our world is changing which is causing more & more large scale “indoor growing” operations are popping up everywhere.  

Indoor Growing - In General

Indoor growing is the act of cultivating plants “inside” VS traditional “outdoor” agriculture where plants are cultivated outside. Indoor growing can have many different advantages basically due to your ability to “take control” almost all growing conditions known as Environmental Factors (Check Out Our Article). The more optimum growing conditions you provide? The better your crops will do growing faster, stronger, and most likely better yields. 

Large Commercial Greenhouse Complex


  • Better control of growing conditions
  • Can control almost all conditions instead of just “some” with outdoor growing
  • Extend the growing season
  • Allow plants that can’t grow outdoors in certain climates to be grown. 
  • So much more!


  • Much higher cost per sqft of growing space.
  • More complicated than traditional outdoor growing where “mother nature” takes care of many environmental factors.


Greenhouses are what most people think of when “Indoor Growing” is brought up. That is because traditionally they have been the center of indoor growing. They provide the benefits of better control of all the environmental factors such as temperature, humidity, CO2 Levels, and so much more like all indoor growing methods. But many places / crops will not require Growing Lights in a Greenhouse unlike the other types of Indoor Growing Environments. This is clearly due to the Greenhouses are usually covered in a transparent material such as glass, plastic, plexiglass, and such. These materials allow natural sun through. 

Greenhouses come in many different forms and size factors from massive commercial greenhouse complexes to tiny “cold frames” that you can’t even walk in. They have many different structural designs from “hoop houses” to more traditional framed greenhouses. They can also range from very economical plain metal frames covered in plastic to very expensive / beautiful iron frames with glass. The types, designs, and purposes are almost endless with Greenhouses.

Grow Rooms

Grow Rooms have grown in popularity over the last few decades. This is due to high level of control they provide AND most important security. Many crops raised in Grow Rooms are of very high value where the grower wants better security than a traditional greenhouse can offer. 

Like a greenhouse, Grow Rooms provide all the benefits of the control ability of all environmental factors. They are also many times more “sanitary” with less pest and disease problems compared to greenhouses. However, they are more costly to setup per SQFT compared to Greenhouses due to they require more ventilation, SQFT inside a building, LIGHT for the plants to grow. This light is provided by one or more types of grow lighting systems. Check out our many articles on Grow Lights such as Different Types of Grow Lights (Click Here)

Grow Tents are extremely popular growing solutions for the person looking to grow couple plants. They are very economical compared to a full blown Grow Room, easily movable to new location, and many other advantages. But they generally only come in up to 8′ X 8′ which is a limiting factor if you plan to continue expanding overtime. 

Quality Grow Tents will come with metal pole system as its “skeleton” support structure. AVOID PLASTIC! The material should be a heavy canvas for longevity with quality zippers / clips for openings. They come in many different sizes ranging from as small as 2′ X 2′ for a corner of a room to the larger 8′ X 8′ more suited as a movable “grow room.”

Grow Boxes or Grow Cabinets are generally the smallest of the growing units. They generally are used in place of a Grow Tent when the grow is only few plants which require top level security. They range from the size of a desktop computer to very large storage cabinets.

Many people DIY build them or you can buy one from multiple builders such as SuperClosets. They can range in cost depending on options and size from $500 to $5000! 

To Close

In closing, “Indoor Growing” is very important means of agriculture. It has been greatly growing in use over last few decades. This started with the most valuable crops, but it now has become way more common in many more different crops. This has been greatly due to the rise in commercial hydroponics which is mainly done in Greenhouses. Indoor Growing has allowed for plants to be grow in different climates more successfully, provide food when late frosts destroyed traditional outdoor crop yields, and so much more.

Hydroponic Growing Environments

No Comments


Hydroponic systems generally do best in well controlled indoor growing environments. This is mostly accomplished by a few different methods. They include greenhouses, grow tents, grow rooms, and grow cabinets. This allows for cleanliness, control of the environmental factors, and more. Controlling the environment increases yields, crop quality, and less issues with the hydroponic system. 

Main Types of Grow Environments


Greenhouses range from small residential wall units to massive commercial operations. Wooden structures with glass have become a things of the past. They have been replaced by metal structure with polycarbonate “glass.” These structures are not only cheaper but last longer than traditional greenhouses. 

Hydroponic Greenhouse Example

  • Provide great environmental control if setup correctly. With heating systems they can be used year around even during harsh winters. 
  • If lighting systems are used, they are used as supplemental light as greenhouses allow for sunlight.
  • Many times provide more room than other grow environment options


  • Generally the most expensive option by far.
  • May be unavailable to people without land to install them on. 
  • Some land especially in HOA’s may have covenant restriction against building a greenhouse at your home.

Grow Rooms

Grow rooms are also a popular option for people that have extra space in their basements. Basically you have a walled off room, walls need to be flat white, and electrical available. You will need to install all the ventilations and grow lighting will be required unlike a greenhouse. But many times people build them similar size or larger than many residential greenhouses. They are mostly seen as the best truly indoor option.

  • Can be done in houses inside HOA’s or restrictive land covenants due to its inside the house. 
  • Depending if you already have a walled off room in your basement, can be much cheaper than building a greenhouse


  • Requires grow lights unlike the greenhouse
  • Can be expensive if you have to wall off a new room in your basement.

Grow Tent

Grow Tents are a great option for people that have less space than a full grow room. They are like their names sounds, a frame holding up a tent to create this controlled environment for your plants. They can also be a great option for someone wanting something the size of a grow room but do not want to wall off their basement. We carry a Mar Hydro 8’X8′ unit that is like a mini grow room in size.

  • Very cheap and affordable option compared to above two.
  • Portable if you ever need to move it.
  • Provides a great controlled growing environment for your plants.


  • Require grow lighting to provide all light for plants
  • Wear out faster than above two more expensive options. But you can get years of service out of a quality product. 

Grow Cabinets / Boxes

This method of controlled growing environment is normally the smallest. They can be as small as a PC up to a large wall cabinet. Most people that use them live in apartments or have limited space. They are popular as they are less obvious in appearance compared to a more affordable grow tent.   

Grow Box example


  • More stealthy in appearance compared to any other option.
  • Many sizes available to fit even small spaces.
  • Portable if needed. 


  • More expensive than a Grow Tent
  • Customization is more difficult 
  • Harder to transport as they can be very heavy

Types of Grow Lighting Systems

No Comments


Every indoor grow from a small residential grow in a closet to large scale greenhouse operations all need grow lights. Grow lights provide all or supplement lighting needs of the plants. The main types used to LED, HID (MH & HPS), and Compact Fluorescent lighting. They all have their advantages and disadvantages.   

LED Grow Lights

LED Grow light spectrum

LED Lighting systems have been around for along time. But in the pass they were much more expensive for the same light intensity as other solutions such as HID or Sodium lighting. This has recently changed so LED Grow Light Systems are becoming the most popular grow light solution for both residential and commercial growing operations. 


  • Lowest energy user
  • Lowest heat production
  • No bulbs to replace on regular basis
  • Most LED systems are full spectrum instead of needing two different bulbs and/or systems for veg and flower stages


  • Generally do not have as good as “light pentration” as other systems so lighting height needs to be monitored and adjusted more. 
  • Most system once they start failing need to be completely replaced instead of just changing a bulb.

Hydro-Unlimited's offering

We highly believe in LED lighting due to its many different advantages that used to be somewhat canceled out due to higher cost. Now with technology and manufacturing improvements of LED, pricing is “in-line” with other solutions making LED grow lighting my #1 suggestion for any grow needing all its light or supplemental lighting. We have partnered with Mars Hydro which has become a leader in quality but affording LED Grow Light Solutions. CHECK OUT OUR ONLINE STORE!

HID (High Intensity Discharge) Grow Lighting System

HID Grow Lights have been the main commercial grow light for years. The bulbs are built like traditional gas bulbs where the bulb is filled with certain gas with two electrodes for charge. HID Lighting has held its position as main grow light due to their ability to produce high light output and brightness dependably. Depending on the type of bulb used, the light spectrum will vary. The two most popular HID bulbs for growing is MH (Metal Halide) and HPS (High Pressure Sodium). The difference is mainly what gas is in the bulb and they create different light spectrums. HID Systems generally consist of Grow Light deflector, bulb, ballast, and power cord. Large systems can also include air cooling and ducting due to the large amount of heat they can put off. Many people get ballasts capable of running both types of bulbs to save on cost. 

MH (Metal Halide) Bulb

Metal Halide bulbs are filled with gas that creates mainly Blue light spectrum. These are usually used for the “vegetative” stage of growth. 

HPS (High Pressure Sodium) Bulb

High Pressure Sodium bulbs are filled with gas that creates mainly Red and Orange light spectrum. HPS is mainly used for the “Flowering” stage of growth. 


  • Good light penetration over other types of grow lights
  • Dependable “time tested” system of grow lights
  • Large selection of reflector, ballast, and bulb combinations available


  • Generates the most heat while in use to the point of larger ones needing air cooling.
  • Bulbs have to replaced regularly to keep light lumens up.
  • Need different bulbs for growing stages.
  • Uses of the most electricity of all the lighting system types by far. 

Compact Fluorescent Grow Lighting

Compact Fluorescent grow light bulbs used to be very popular in small scale grows as they were affordable, low energy use, and created way less heat than HID Lights. They have lowered in popularity with the pricing of LED grow lights coming so far down. People that use them now mostly do for “supplemental” light such as “side lights” instead of primary lighting system. 


  • Low cost 
  • Does not require a ballast like HID
  • Low energy use


  • Limited light penetration ability
  • Requires different bulbs for different growth stages due to not being full spectrum like LED
  • Bulbs need to be replaced regularly for quality of light produced.
