The Best Grow Box 2018 To Cultivate As A Pro

What Is A Grow Box, And Where Is It Used?

The name speaks for itself: a grow box is a special closed construction for cultivating plants and sustaining perfect conditions. This device allows the user to ensure:

  • proper ventilation and elimination of odors;
  • optimal lighting according to the required schedule;
  • normal temperature and insulation;
  • protection against adverse weather conditions and sneaky eyes.

There are several types of grow boxes depending on the construction, configuration, and size.

Basic Grow Box

A small indoor grow box can be the size of a computer case, while big professional models can be as large as a dresser. This is a closed construction that is usually made of metal and plastic and features lighting, ventilation (optional), and climate control. That’s the most common solution for indoor harvesting when plants are cultivated by a single person.

Grow Tent

This construction consists of multiple metal or plastic supports covered with light-proof fabric. This is a recommendable option for those who need a cost-efficient system that would be easy in installation. Inside, a tent can be covered with a reflective material (plastic covers have 94% reflectivity). Insulation blocks the sound and helps to sustain normal temperature. Most grow tents don’t have light and other equipment.

Grow Closets

Closets have pretty much the same shape, size and capacity as grow tents, but are made of different materials (usually are produced of a steel frame with aluminum walls). Inside, they’re lined with reflective materials. As a rule, grow closets have several compartments for vegetation and flowering. Besides, such models usually feature all growing equipment and are pre-assembled, which makes them great for new gardeners. When we had to review grow box solutions, we figured out that’s the most optimal choice for gardeners who want a rich harvest.

Grow Rooms

Those who need a lot of growing space organize grow rooms: this construction is made of similar materials as grow tents. They can include several sections and come with additional features or products. The most advanced models come with the reflective interior, customization options, ventilation ports, and a sturdy frame. Cooling and lighting systems are usually included. Although grow rooms seem to be hard to maintain, they feature all essential devices for sustaining an optimal ecosystem.

Aspects To Consider

In order to choose the best grow box to meet your cultivating demands, pay utmost attention to the following points.

Wattage

Another important feature is electricity consumption. If you’re afraid of enormous electricity bills, choose a cost-efficient model that doesn’t consume much energy.

Full Automated

If you’re absent for a long time and have fastidious plants, automated grow box is a must. Using such a device, you can customize the temperature, lighting and moisturizing according to your needs. A timer will help you to ensure proper conditions.

Light Type

For large rooms with proper ventilation, choose High-Intensity Discharge (HID) lights. For small rooms, Compact Fluorescent lights (CFL) will go. If you have a grow box and want to save energy, buy Light Emitting Diode (LED) fixtures – they don’t consume much electricity but tend to be a bit more expensive.

Odor Control

Depending on the plants you grow, you might need an efficient ventilation system carbon filter grow box will keep smells locked. Such plants as marijuana and some flowers can emit a very strong odor during blossoming.

Light Proof

To protect plants against extra light exposure, choose a grow box with reflective walls. It will also keep the plants unnoticed by guests.

Grandma's Secret Garden 4.0

9 Plant LED Grow Box – Grandma’s Secret Garden 4.0

Review:

This is a non-expensive solution that has its pros and cons. We would recommend using it for growing some flowers and eatable plants somewhere in your garage rather than using it as a discreet leaf grow box. Why? First, because it emits noise. Secondly, because the light is visible. The grow box is equipped with all necessary growing equipment including nine LED lights. There are two compartments (veg and flowering setting).

Our opinion:

Such model would be recommended for starters who grow usual plants and aren’t concerned with discreetness. It’s non-expensive, that’s why its quality leaves a lot to be desired.

PROS

  • cheaper than metal automated grow boxes;
  • includes lights and other growing equipment;
  • has 2 compartments.

CONS

  • plastic construction instead of the metal frame and walls (thus, the price isn’t justified);
  • too noisy;
  • emits light.
Grow Tent Kit Complete With 400-Watt HPS Grow Light

HTGSupply Grow Tent Kit Complete With 400-Watt HPS Grow Light

Review:

If you want a ready solution, this tent would be a great option because it already includes everything for cultivation: lights, light hangers, mechanical timer, thermometer and hygrometer, fan, a hydroponic system, and a combo-pack of nutrients. The tent is made of black light-absorbing textile with light reflection inside. The instruction is included. The tent can be installed anywhere in the house, though it doesn’t look like a discreet place.

Our opinion:

This is best grow box for beginners: non-expensive, features all necessary equipment, lightweight. If you don’t go illegal, this growing solution is just the thing.

PROS

  • lightweight and compact;
  • all included in the kit;
  • non-expensive.

CONS

  • emits noise and smell – it’s not suitable for discreet growing.
TopoGrow LED Grow Tent Complete Kit

TopoGrow LED Grow Tent Complete Kit

Review:

TopoGrow grow box is a versatile solution for growing a couple of plants. This model features everything for cultivation: LED lights (full spectrum), cooling fans, a carbon layer for smell absorption, and a reflective waterproof diamond layer. This design allows for the whole cycle of growing (suitable for vegetables, fruits, and herbs). Three separate boxes are included.

Our opinion:

This non-expensive grow tent should rather be used by beginners who only start learning the process. The construction should be assembled, so be ready for some elbow grease. It’s not the best option for discreet harvesting – smell and light are still emitted.

PROS

  • easy setup;
  • cheap;
  • the kit includes the basic stuff for growing.

CONS

  • no instruction on ventilation setup;
  • not much space (2-3 plants will fit in).
Cash Crop 5.0 - 6 Plant LED Hydroponics Grow Box

Cash Crop 5.0 – 6 Plant LED Hydroponics Grow Box

Review:

Users in search of a small, sturdy box, are recommended to take Cash Crop grow box into consideration. This model features metal construction, insulation, reflective layer inside, pots, nutrients, and other equipment for cultivation. The box itself isn’t large: it accommodates 2-6 plants depending on their size. No carbon filter is included –it’s bought separately.

Our opinion:

Judging by reviews, this product provides half-baked experience: lights are weak, fans are noisy, and some components should be purchased separately. You can find a better option for such money, and this grow box should be customized, which involves extra costs.

PROS

  • metal construction;
  • the kit comes with some growing equipment.

CONS

  • carbon filter required for smell elimination;
  • poor functionality for such a price;
  • noisy.

PROS

  • high-quality materials and reliable construction;
  • non-expensive.

Dealzer Grandma's Secret Garden 3.0

Dealzer Grandma’s Secret Garden 3.0 – Hydroponics Grow Box

Review:

If you want something sturdier than a textile construction, order Dealzer grow box – it’s made of wood. It accommodates a 9-plant hydroponics system and allows for growing any plants. Small fans and carbon filters are included. According to reviews, some light and smell are emitted, and the unit produces noise, so it’s not the best option for growing discreetly.

Our opinion:

An average-quality choice for those who want to grow plants indoors and don’t care whether the box will be noticed. A bit overpriced item.

PROS

  • fans and lights are included;
  • 9 plants can be grown with a hydroponics system.

CONS

  • overpriced;
  • emits smell, light, and noise.

Here Are Some Hydroponics Tips

There are a lot of factors that should be considered aside from a grow box: weed and other herbs need special care and specific conditions for normal growth. Here are a few professional tips to get maximum from your efforts:

  1. Sanitize your equipment (pipes, filters, reservoirs, etc) – that will eliminate the risk of pathogen development and root rotting. Get a few bottles of alcohol and hydrogen peroxide to clean equipment regularly.
  2. Use clean pH neutral water (ideal pH level is 7). If you can’t get such water, use reverse osmosis (RO) system to create optimal neutral conditions. Distilled water is also suitable.
  3. Sustain optimal temperature. Ideally, the water in the hydroponics system should be about  65 F (18 C) to prevent the formation of algae and provide enough nutrients. Air can be warmer – about 75 F (24 C).
  4. Ensure a normal humidity level in your indoor marijuana grow box: at early stage of development, plants need 60-70% humidity. In the blooming phase, it can be around 40%.
  5. Keep proper lighting. The type of lights depends on the available space for plants, the distance between them, and your budget. Light Emitting Diode (LED) fixtures are perfect for small boxes, but they are quite expensive.
  6. Keep the box ventilated properly – that helps to maintain a normal temperature and provide plants with carbon dioxide.
  7. Keep track of EC (Electrical conductivity) measure: it will tell you how much nutrients the circulating water has. For seedlings, EC level can be less than 1.3, for clones – as low as 0.5. While the plant is growing, you should gradually increase EC to 2.0, in the flowering stage – 2.5.
  8.  Make sure you get seeds from a reliable source. Even if you use the best weed grow box, the plant can only give what’s genetically predisposed.
  9. Don’t rely on luck – control the process of growing. Keep records, take care about temperatures, EC level, humidity, and other aspects to make informed decisions and provide plants with the best conditions.

Conclusion And Our Recommendations

The choice of the grow box depends on your needs. If you don’t care about odor and sturdiness of construction, choose the model from HTGSupply – it features all necessary equipment. However, if paying over $500 for the whole kit is a bit too much for you, consider a cheap box that can be customized. Consider a simple $100 box like GROWNEER Mylar, and add extra equipment that you prefer.
If you need the best marijuana grow box (the model that reduces smell and noise to the minimum), we would recommend Yield Machine Max 4 Foot LED Grow Box. Unlike its analogs that cost around $1,500 and higher, it is twice less expensive and provides the same excellent level of automated maintenance. This is a top pick for discreet harvesting.
