Hello Joe I wouldn't worry about taking them outside they are under the MH and that is the best place for them

As for the fresh air, well you have a fan on them so you're doing you're best and they are looking fine. Maybe the stems look a bit thin but they'll grow thicker and the fan will encourage that.


Just try to let them get on with the growing and keep the updates up


By the way Joe are you planning to flower them under the MH as well ? .................. The MH will flower them as it does produce "red light" but the bud weight wiil be down slightly on using a HPS light.
I wouldn't worry though, it's a first grow and once you have sucsessfully completed it, then you can concentrate on the "fine tunning" for you're future grows
