Please someone help me!!!!!!!!!!!!!!!!!!!!!

I have a quick question about ventilation im not a first time grower but i am a beginner now is it ok if i have my windows open for ventilation plus in my room i have a ceiling fan as well as 1 oscolating fan one reg small fan and an air purifier in my closet which i am growing in i also have central air conditioning and the temps in here are alwyas good but the only reason y i ask is becasue this is the first time growing in this spot instead of basement cause it was a small closet in basement and there wa no fresh air and i no plant need co2 from the fresh air please help i need any help?????!!!!!!!!!!!!!!!!!!!!!!!!!!

I would suggest going back to the basement and getting a C02 boost bag maybe. They are relatively inexpensive. The idea of a ground level or even a second story closet grow with no odor filtration except for an open window seems high risk. You want to create a controlled environment. I understand not everyone wants to or is able to invest money into a small or beginning grow. But the way I see it, If I invest a few hundred on start up to double my yield, It is worth it. Ventilation is very important. If you can't pull in proper amounts of fresh air you can end up with lots of issues.

I think it's fine during veg, (my previous plant didn't smell at all while it was in a cloth closet in my room) but yeah, eventually you'll have to face the odor issues and need regular air exchange to deal with it. It's good to control the temps too.

What kinda lights are you using? Are you using HID lamps?
