So I’m growing in a closet. And for my carbon filter. I don’t have another room for fresh air to come in, it’s just a ceiling, I know this might seem like a dumb question but I’m at a road block and I’m not sure what to do
Super newb question but I was wondering if you can use multiple nutrients like 3-4 for veg and flower. Does each nutrient have a certain purpose so u can only use it accordingly?
