Grow Cabinets – The 7 Best Stealth Grow Boxes for Marijuana

Hydroponic growers often struggle with providing uniform and ideal conditions to their plants. Indoor marijuana growers are dually challenged because they also worry about odor control and keeping their cannabis plants hidden. Fortunately, Grow Cabinets provide a simple solution to these common problems.   Often referred to as Grow Boxes, Stealth Cabinets, Grow Lockers, and Marijuana Cabinets, these self-contained growing environments mimic everything a gardener needs to cultivate healthy plants. They allow for the complete customization of the growing conditions inside the cabinets and are adjustable to suit the specific needs of a plant throughout the entire growing cycle.

Using a grow cabinet for cultivating cannabis is especially useful. This is because of their stealthy, inconspicuous design, locking features, and ability to eliminate odors. Lighting is provided for inside grow boxes, and seedlings, clones, and mature plants all benefit from the efficiencies of these compact and stable environments.

Let’s take a closer look a the benefits of using a grow box for growing weed,  and then review the 7 top rated and best grow cabinets that you can buy.

Top 7 Advantages to Using a Grow Cabinet

  • Complete – Grow Cabinets come complete will fans and filters for ventilation and air quality, grow lights and reflective interiors for superior lighting during all cycles of growth and locking capabilities for added protection (especially helpful to cannabis growers). Most grow boxes also include other components, such as pumps, timers, nutrients, pH adjusters, and grow media.
  • Adaptable – Gardeners can adjust the conditions within their grow cabinets, including the lighting, temperature, humidity, ventilation, and watering schedule. These enclosed grow boxes allow the gardener to produce the highest quality indoor crops possible because the grower is in total control of deciding and implementing the best growing environment. Seedlings, clones, and mature plants can be effectively grown inside grow lockers, as well as hydroponic or soil crops (such as cannabis, herbs, vegetables, and more).
  • Compact –While grow tents are often used by marijuana gardeners and other indoor growers to create ideal conditions for plants, these have a bulkier composition and take up more space than their smaller grow cabinet cousins. Most grow cabinets are narrow and stand only a few feet tall, making them incredibly space-saving and adaptable to any indoor setting. Grow cabinets are small enough to be used in an apartment, bedroom, closets, basement, garage, hallway, or elsewhere. Plus, most are lightweight, transportable, and easy to set up.
  • Discreet – Another advantage over grow tents – especially for cannabis growers – is the inconspicuous nature of grow cabinets. Their appearance resembles a dorm refrigerator, file cabinet, safe box, or storage locker. Most stealth grow cabinets require a key, padlock, or personalized code to open, providing an added layer of protection. It is no coincidence, then, that marijuana growers feel especially secure growing their weed inside a grow cabinet.
  • Odor Control – As you may know, marijuana has a distinctive and pungent odor. Vegetables and herbs – much less so. Therefore, cannabis cultivators will especially appreciate the odor-eliminating features of grow cabinets. Carbon (charcoal) filters are used to thwart the smell of weed so your living space remains odor-free and your marijuana growing remains secretive and nearly undetectable.
  • Effective – Providing ideal conditions means that grow cabinets can produce the highest yielding and best quality crops. There is less monitoring and maintenance required because all the components inside a grow box are automated to do the work for you. And indoor gardening means that crops can grow year-round and at an arm’s length away. Grow cabinets also provide protection against bugs and other pests.
  • Economical – Don’t be alarmed by some of the high price tags. As we mentioned before, grow cabinets come complete with all the components you need to start growing (including grow lights, filter, fans, pumps, and grow media). Therefore, you don’t need to purchase these items separately. Plus, grow cabinets will provide years of continuous harvests. So an investment in a grow cabinet is a wise and economical investment in the long run.
