How Does a Grow Box Work?

If you’re interested in growing marijuana in a grow box, it will help you to first know exactly how it works. A grow cabinet produces an environment that is quite similar to the effects produced by Mother Nature – however, you will have more control over the light, humidity, and other factors, since everything will be enclosed in one tiny box.

These devices allow you to control every aspect of growing weed, from the ventilation to the light and the water. You won’t have to rely on the weather (or even the strength of your own memory!) in order to produce a healthy environment for your plants. You also don’t need to worry about bugs or diseases.

An indoor marijuana grow box is not only effective at producing high, healthy yields of marijuana, but it’s also small and discreet. Nobody will be able to spy on you or wonder what you are growing. You can often leave them for weeks at a time without having to do anything at all. Long story short, marijuana grow box is a smart investment, even for someone who is just starting out with growing weed.

Benefits of Using a Grow Box

There are many advantages to using a hidden grow box. Not only does one of these all-in-one grow boxes help to hide your growing operation, but it can perform several other vital functions, too.

A weed incubator is generally equipped with everything to help you get started. Although not as all-inclusive as one of the best marijuana grow tent kits, a grow cabinet will usually come with high-quality LED grow lights, filters and fans for improved airflow and ventilation, and reflective interiors that will distribute light to all of your plants.

The best single plant grow boxes will also give you other features, too. You might get one that has timers, pumps, pH adjusters to accommodate poor soil pH, nutrients, and more. You might even get potting soil included with your grow box! Most grow boxes provide ample light during all growing conditions, including the vegetative and flowering state, along with locking capabilities to protect your automated grow box from prying eyes.

The best grow cabinet will also be highly adaptable. You will be able to adjust everything from the lighting to the humidity, temperature, and ventilation. Some even allow for changes in your watering schedule. An enclosed grow cabinet will help you produce the best indoor weed possible because you will be in charge of every aspect of your growing environment. You can grow clones, seedlings, and even mature plants inside a weed incubator, and you can even produce soil or hydroponic crops like vegetables and herbs, too.

One of these units doesn’t have to be a small grow box to be compact, either. Grow tents are frequently used by indoor growers, but these can be bulkier and will take up significantly more room than a small grow cabinet. These tend to be only a couple feet tall and are quite narrow, which means you can save space and fit them into any indoor grow setting. They can be used in closes, bedrooms, apartments, garages, or anywhere else you have space to set one up. They’re lightweight and portable, with most taking only a few minutes to set up – so it won’t be a pain to change things around, either.

As we already mentioned, a hidden marijuana grow box will also be more discreet than its grow tent cousin. You won’t have to worry about your neighbors wondering what you have in your massive grow tent. A smell-proof grow cabinet will eliminate marijuana odors and it will look just like a file cabinet, storage locker, or dormitory refrigerator. Many of these require a key or code to open, giving you an additional level of protection. You won’t have to worry about anyone wondering what you are growing, because a grow box doesn’t even look like it could be growing anything.

Grow boxes have substantial odor control, which is helpful when you are growing marijuana. These are usually equipped with charcoal or carbon filters that will divert and disguise the smell of growing weed. Your room can remain free of odors!

And you don’t have to compromise the removal of odors for the quality of your crop, either. Grow cabinets produce some of the best yields and highest-quality weed. You won’t have to monitor or maintain anything – everything inside your grow box will handle all the work. You can grow weed year-round without having to worry about the climate, diseases, or any pests.

Finally, a good grow cabinet doesn’t have to be expensive. While these tend to come at higher prices than your standard grow tent, there’s a serious bargain here – remember, a good grow box is going to come with all of the components you need to get started, including your LED grow lights, filters, fans, and even your growing media. You won’t have to purchase these items separately, which can save you some time, money, and stress when you leave items out that you didn’t know you actually needed. You’ll get your money’s worth out of one of these economical units!

Recap

Hopefully, we have told you all the basic knowledge with our growing box reviews. Whether you are a unique hydroponics grower or prefer a more traditional style of growing weed, stealth grow box can help you meet your growing goals. You’ll have fantastic yields with marijuana grow box, and the best grow box on the market will make your job a lot easier – and a lot more discreet, too.

Are you thinking about growing and cultivating your own marijuana indoors? Make things more discreet by using these best marijuana grow boxes.

Hydroponics Cannabis Growing Guide

Hydroponics is a method of cultivating plants, specifically cannabis in this case, in a solution of water and nutrients.

Contents:

As the name may suggest, hydroponics is a soilless method of growing cannabis using water as the primary medium. Within a hydroponic setup, cannabis plants are grown in buckets or baskets filled with an inert growing medium, and are suspended over a tank full of water. The water is filled with all of the nutrients plants need to survive and thrive, and air stones are used to aerate the tank. This basic model manifests in many different forms and systems, with different growers preferring different setups. There are many advantages to hydroponic cultivation, all of which will be covered in this article. But first, let’s delve into the history of this fascinating art form.

THE HISTORY OF HYDROPONICS

Hydroponic cultivation might initially seem like the result of modern advances in technology. But this couldn’t be further from the truth. The origins of growing plants in water goes back thousands of years into human history. The famous Hanging Gardens of Babylon, created in 600 BCE, are theorised to have utilised hydroponic principles. The region located next to the Euphrates was naturally dry and arid. It’s believed the crops of the garden were nurtured using a trickle-system starting at the river.

Moving closer in time to the 10th and 11th centuries, the Aztec civilisation was also known to utilise hydroponics to provide sustenance to their society. After being forced from their land via conflict, these people settled at Lake Tenochtitlan. They proceeded to build floating rafts topped with soil, allowing crops to grow through the tap layer and spread their roots into the waters below.

More recent, but still distant, examples of hydroponic growing involve the English scientist John Woodward in 1699. His work involved cultivating spearmint plants in water. He found that the plant species grew faster within a water source mixed with soil.

The history of hydroponics has shown how effective this method can be in many different settings and scenarios, with cannabis cultivation being no exception. Let’s explore the advantages of this interesting method, and how to apply it to growing great weed.

THE ADVANTAGES OF HYDROPONIC GROWING

If you talk to a grower who has experience with hydroponic growing, one of the first things they’ll probably tell you is that their hydroponic plants grow much, much faster than those in soil. This is a prime advantage of this method of cultivation—hydroponic plants usually grow 30–50% faster and often provide larger yields. A large reason for this is that nutrients within a hydroponic system are much more readily available to plants. The nutrients are suspended in water and enter directly into the root system as there is no soil to navigate through. In contrast, plants growing in soil must search through the medium in order to uptake nutrients from below. Easy access to nutrients allows plants to preserve energy, which is then diverted to growth efforts instead.

MATERIALS NEEDED TO MAKE A DIY HYDROPONIC SYSTEM

If you go the DIY route, check out the brief guide below. The list covers all of the equipment you need to construct a basic indoor setup. Simply find the product that suits you for each listed item. Buying your gear separately allows you to invest more heavily into important items such as lighting while reducing the cost in other areas.

Here’s what you’ll need:

a) Lighting (LED or HPS)

b) Lighting hangers

d) Hydroponic reservoir and tray

e) Airstone and pump

f) Growing medium (e.g. coco coir)

g) Net mesh planting pots

i) Ventilation fan and ducting tubes

j) Carbon filter

k) Oscillating fan

l) Hydroponic nutrients

m) pH and PPM meters

THE COST OF GROWING WITH HYDROPONICS

When thinking about hydroponics, you might picture a high-tech setup: automated switches, flashing lights, ticking timers. However, the cost of a hydroponic system all depends on how much money you’re willing to splash. They range from a simple plastic bucket all the way to self-draining and flooding systems. To save time, invest in a cheap hydroponic starter kit. These include all of the materials you need to get from seed to harvest. You can purchase one for around £200 (€235).

1. CHOOSE A GROWING MEDIUM TO GET THINGS STARTED

Now that we have covered the history and benefits of hydroponic growing, it’s time to get things started. To begin, you’ll need to select a growing medium—a substance that will hold in place the intersection of the stem and roots. From this location, the roots will grow down into the water in search of nutrients. The inert medium also allows good air access to the top of the roots. There is a huge list of different media used by cultivators, with those below being the most common. Each medium has its own unique benefits, and some work better with different systems. It’s all about experimentation when starting out to see which works best for you.

  • CLAY PEBBLES

As one of the most popular options, clay pebbles are excellent at aerating root systems. Clay pebbles sometimes require that growers alter the pH in order to provide an optimal growing environment, however, pre-altered pebbles can be purchased. You’ll need to place clay pebbles into a plastic hydroponic basket that has spaces for roots to grow through.

  • ROCKWOOL

Rockwool is another popular choice, and is a substance created using volcanic rocks with a wool texture, hence the name. Rockwool has a tremendous capacity to retain water, which allows for good hydration of the upper root system. Rockwool can be placed within a hydroponic basket, but can also be lodged directly into the top of a bucket or tank lid without.

  • PERLITE

Perlite is a volcanic glass that expands when exposed to high temperatures. It’s often used in garden soils to provide aeration, which is exactly why it’s beneficial to use as a hydroponic growing medium for cannabis.

  • COCO COIR

Coco coir is a good sustainable option for a growing medium. As the fibre from coconuts, coco coir allows for good aeration and moisture retention. Coconut fibres are also known to protect roots from infection due to the presence of plant-stimulating hormones.

2. CHOOSE A HYDROPONIC GROWING SETUP FOR YOUR PLANTS TO THRIVE IN

Now that you’ve selected a growing medium, it’s time to choose which type of hydroponic setup to use. All systems are similar in that they utilise a nutrient-enriched water solution. However, setups can vary widely depending on factors such as water exposure and circulation. Most of the following systems can be purchased, but those with DIY skills could easily make them by using buckets, drills, pumps, and air stones.

DEEP WATER CULTURE

Deep water culture is a good place to start for beginners, and is likely the cheapest option. Plants are placed in buckets filled with a nutrient solution and an air pump provides a constant supply of oxygen.

EBB AND FLOW

An ebb and flow (also known as flood and drain) system features water that, well, ebbs and flows. These systems consist of several buckets suspended above a growing tray that features a water inlet and outlet. Both of these waterways are connected to an external tank that contains nutrients, an air stone to aerate the water supply, and a pump to move water into the growing tray. The roots in these systems are not continuously submerged within water. Instead, water periodically floods the growing tray with fresh oxygen and nutrient-enriched water. Once the pump cycle ends, all of the water drains back into the external tank.

This system allows for periodic feeding. The time when the growing tray is empty allows growers to easily tend to plant roots and harvest plants.

DRIP SYSTEM

A drip system in hydroponics is very similar to a drip irrigation system when growing in soil. This system consists of a large tray filled with growing medium, such as clay pebbles. Plants are placed directly into the medium, and each has its own drip pipe nearby. An external water tank with a pump and air stones constantly supplies a drip feed of water over each plant. The roots of these plants are constantly exposed to air, and the excess water drips down the medium and back into the external tank.

NUTRIENT FILM TECHNIQUE

If deep water culture is the equivalent of growing cannabis plants in a pond, then the nutrient film technique is the equivalent of growing weed over a river. This system involves placing plants into a tube that is angled, so water can enter at one side and exit at the other via gravity. The roots grow down into the tube, where they are exposed to the flowing water. The water enters from a tank with an air stone and pump, and returns back once the cycle is complete.

WICK SYSTEM

A wick system is a basic hydroponic setup that uses a growing tray similar to the drip system filled with clay pebbles. Under the tray is a tank of water, from which several wicks exit and enter the growing medium. Water travels up the wicks and passively hydrates the medium. No pump is required for this system.

AEROPONICS

Aeroponics is perhaps the most futuristic version of hydroponic growing, and uses misted water dispersed through the air to optimise aeration and hydration. Plants are placed into the top of a large tank of water filling the bottom 25%. Under the water is a pump that sends water into misters underneath the root systems. This fine mist constantly soaks the roots, allowing plants to receive massive quantities of air and water simultaneously.

3. PREPARE YOUR SYSTEM TO ENSURE A SUCCESSFUL GROW

After choosing your system, it’s important to prepare it well to prevent any detrimental situations. The damp and dark nature of water tanks is an ideal growing environment for a host of pathogens. Before running your system, you will need to sterilise your equipment to minimise the chances of contamination. Wipe down all of your buckets, trays, pipes, and tanks with rubbing alcohol, hot water, and peroxide. Once your system is sterilised, begin following the instructions to set it up correctly.

YOU’LL NEED TO MAINTAIN YOUR SYSTEM REGULARLY

Every hydroponic system requires frequent maintenance to provide an optimal growing environment. Below are all of the major factors you need to be aware of.

A) ALWAYS MONITOR PH

You’ll need to constantly test the pH of the water to ensure an optimal growing environment. Nutrients are more available to plants when the environment is slightly more acidic. Therefore, a pH of 5.5–5.8 is required. Use a pH testing kit to take regular readings, and be sure to change the solution weekly to maintain this range. During flowering, a pH of 6 is preferred.

B) TRY TO KEEP YOUR WATER TEMPERATURE AT AROUND 20°C

Hydroponic cannabis has an ideal temperature of 20°C. This factor can be monitored using a water thermometer and altered using a water heater if the temperatures are too low.

C) PROVIDE THE CORRECT QUANTITY OF NUTRIENTS

Hydroponic plants require the same nutrients as their soil-based counterparts. The easiest way to go about feeding your plants is by purchasing hydroponic nutrient solutions that contain all of the required substances for both the vegetation and blooming periods. Products will also describe how often to add nutrients back into your system and how much dilution is required.

D) KEEP THINGS CLEAN TO AVOID CONTAMINATION

Both growing trays and tanks require emptying and cleaning around every two weeks. This process will keep the roots of your plants safe against invading pathogens and diseases. Repeat the same process mentioned above when initially preparing your system.

E) SELECTING A STRAIN FOR HYDROPONIC GROWING

Strain selection is an important factor of hydroponic growing. Plants grown within these systems are free to uptake nutrients extremely fast, which often results in explosive and rapid growth. For this reason, selecting a large, towering sativa variety won’t be your best choice, especially if your system resides within an indoor grow tent.

Smaller and more compact strains are ideal for indoor hydroponic systems. Beginning with a smaller strain is advantageous for several reasons. For one, it will let you cultivate several plants within a smaller space, allowing for more diversity and potentially bigger yields. Additionally, if your plants do go through a growth spurt, you’ll have room to deal with such sudden surges in height.

Below are two strains that we recommend for hydroponic growing.

WHITE WIDOW

White Widow is a perfectly balanced hybrid strain that features 50% indica genetics and 50% sativa genetics. She was created using parent strain White Widow S1, and provides a well-balanced high that stimulates and excites the mind whilst relaxing and stoning the body. A THC level of 19% ensures a powerful psychoactive experience that lasts several hours. These flowers contain a terpene profile that emanates grounding tastes and smells of earth and pine.

White Widow will reach a height of 60–100cm when grown indoors, making her an ideal candidate for the spatial demands of a hydroponic growing operation. Expect good yields of 450–500g/m² after a flowering period of 8–9 weeks.

Hydroponics is a method of cultivating plants, specifically cannabis in this case, in a solution of water and nutrients.
