What Are the Advantages of a Good Grow Box?

A grow box, or grow tent, is simply an enclosed space where you can grow plants. As technology continues to develop, they’ve moved from just being small tents with some LED lights into highly sophisticated boxes that allow you to control temperature and every other aspect of your plant’s environment, so you can yield the biggest return.

There’s even a type of automated grow box that you can control from your phone. It allows you to remotely monitor and automate your  nutrient dosing, pH sensoring and temperature control. So, what are some of the advantages of a best grow box?

  • Grow all the time: When you use a grow box, you’re not dependent on external weather conditions. This means that your plants can get the max yield from your plants year-round, regardless of outside temperature.
  • Discreet: Grow tents are usually fully enclosed, and nobody can see inside unless they open the box. Also, marijuana has a distinctive smell when it’s growing, which can be offensive to some. By having a stealth cabinet with a full ventilation system, you won’t have to worry about other people knowing about your cannabis growing project.
  • Saves space: Grow tents can be as small or as big as you want. The way they’re organized means that you can save on space, which is great if you live in a small apartment or are limited in how much space you have.
  • Full control: With a growth tent, you can control all of the growing parameters to help you grow a tall, healthy plant: the amount of nutrients, water, light, air, and temperature. In time, you can go more deep and experiment, you can look in to air ventilation fans, and different lighting to find the optimal growing conditions for your particular marijuana strain and get top results.

How to Choose the Best Grow Cabinet

What tent you choose will ultimately depend on your needs, such as size, price, the number of plants you want to grow, and experience level. Beginners will do best with a small tent and LED lights. This will provide a basic introduction to grow cabinets and finding out what you actually need from your grow tent or cabinet.

Apart from budget, your biggest consideration should be the number of plants you want to grow and the space you have to grow them. Remember that some parts of these grow cabinets are on the outside and make sure you factor this into your considerations.

Tents can range from tiny, 2ft x 2ft up to 10ft x 20ft, which can fit up to 200 plants. With size comes lighting and air ventilation fans, and the bigger the tent, the more lights you’ll need. The more lighting you get, the more heat you’ll be generating, the more fans you’ll need for proper air ventilation. You need to find a size that balances all of these factors in a way that maximizes plant growth.

If you’re a beginner, the best option is to start small and work your way up, maybe evenutually dive in to deep water culture as your growing skills progress. Once you have more experience, you’ll be familiar with the various aspects of cultivation in a grow tent and be more knowledgeable about what you need and what you don’t.

In Conclusion – Grow Cabinet

A grow tent is an ideal way to cultivate marijuana indoors, you can have a successful harvest regardless of the outdoor temperature. You can use stealth cabinets to prevent your weed farm offending others and grow cabinets in general offer many advantages. With a best grow box, you can cultivate your plants year-round and can control all the growing parameters that can affect bud development and overall plant growth.
