i have a 400 dual spectrum light going at the moment.
outlet pc fan (120mm) running directly into loft (no pipe, but has activated carbon filter).
i have an inlet duct as well (5 metres but 1.5 metre stretched out in loft), cold air breezes out of it which makes me think cold air is moving through the loft alot. it has no fan attached!

1 plant growing (lowryder # 2) and 2 tomatoe plants, lol.
closet is like 1.5 metres squared and 8 feet hight.


my question is, will this (very small really) grow, cause alot of condensation in the loft. is there adequate airflow to stop that happening anyway?
im not sure about this i dont wanna wreck the loft.

to me sense says if the inlet air is cold, it must be alright up there?

Where do you live? Most attics/lofts are humid and hot most of the time. No matter, your space should've already had more than adequate exhaust, if it had passed some type of inspection. You should be ok. I deal with this daily as my career is metal roofing.

If its cold up there and you dump hot air in then you'll surely have condensation. But most spaces have a temp setting to keep it relatively even throughout the year. You'll have temp spikes but the factory setting should keep those to a minimum.
