Grow QuestionsDo I need a exhaust fan?

Do I need a exhaust fan?

Autogrowzstarted grow question 4 years ago

Do I really need a exhaust and intake fan for a 20x35x63 grow tent? Would a exhaust fan alone work and let air passively come in from a bottom “vent”.? Thanks!!

Depends on if you want your plant/plants to grow fast or at all. You're going to want an intake and exhaust fan unless you're growing outside. Also unless you're household and you're neighbors love the smell of weed you're going to want to invest in a carbon filter by at least weeks 4-5

If you can add a fan to increase airflow then go for, the more air circulation the better.

Привет, бро! У тебя в палатке выводной канал 100mm в диаметре!? Тебе подойдет 100mm экономичный 8w вытяжной канальный вентилятор. Он тянет 100 кубических метров воздуха в час! Этого хватит чтоб сделать супер воздухообмен в твоей палатке! Но, рекомендую подсоединить его через управляющий димер! Это позволит тебе контролировать его обороты, чтоб палатка сильно не втягивалась внутрь себя при его работе! Вводной вентилятор не нужен! Выводной будет справляться с двумя задачами сразу! Позаботься только о вентиляторах обдува растения!!! 👆 Удачи, брат! ✊😇

Hey I have a tent 24x24x48 and I put in a 4” blow fan for the exhaust and it really made a huge difference with my temps and my humidity. I would get at least a fan for the exhaust Happy growing
