Light is everything for your weed plant. 

Therefore, you have to ensure your grow box will have enough lighting. 

LED lights are the best options because of their efficiency and better heat management. Moreover, they are cost-effective too when it comes to electricity consumption. 

However, in the market, you can also find HPS, HID, and more lighting options. 


We recommend you not to opt for HID lights because of their external ballast. And, as you are making a limited space grow box, therefore, it will not be practical to add things that cover more space. 

Therefore, you have to make sure that your DIY marijuana grow box have appropriate 

2. Air

Your weed plants need proper ventilation.

Not only for photosynthesis but also for the heat management that will be produced by the lighting in the grow area. Moreover, proper ventilation also keeps the smell away. 

For heat management, you can install an exhaust fan or a fan at the top of your grow box. Which will throw out the air from the grow box and ensure proper air circulation. 

You can also add another fan to your canopy depending upon the situation. It completely depends on you that how much you want to put effort into each factor. 

3. Temperature

This is another crucial factor to take care of. 

As weed plants need the right amount of heat and temperature to grow, therefore, you have to ensure that along with lighting and ventilation, your grow space has maintained the required temperature. 

Also, during different climate conditions, you have to ensure your grow space has the appropriate temperature for the plants. 

4. Size of grow box

The size of grow box might vary depending upon the requirement you will have. Also, it depends upon the space you have available and how many weed plants you want to grow in it. Usually, beginners or hobby growers make 1x1m grow tents. 

Though we recommend you make your grow box tall and large enough so that your plants can spread comfortably after maturing. Around 1.5m to 2m in height is good enough. 

Overall, it all depends upon you! How much you want from your grow box and hence how you want to build it. 

5. Waterproofing

Make sure to consider this factor while choosing the framing material and covering material for your grow box. As you know, your weed plants need regular water and nutrients. Therefore, make sure your grow box is waterproof and does not spoil with even splash or spills. 

Though in the market, you can easily get the one that is completely safe from water and ideal for the growing space.
