Grow tent allows you to grow plants indoors. It should be noted from the ventilation diagram here when you have a grow tent, the success of the growth of plants will depend on how well the tent is ventilated. At the same time, with ventilation in the tent, you will get rid of the excess heat that may be detrimental to the plants. As shown here, if you have kept the filter inside, then it will purify the purified air outside the tent. If you have added the filter outside, it will work as an intake filter. You can create such ventilation diagrams using EdrawMax Online. The tool comes with free templates and symbols that ease creating such ventilation diagrams.
