Just saw your journal from your question you asked in the FAQ, I have no comment on that as an experienced grower, but it was nice to see another UK grower. I’m sure there is plenty here, just not often said.
We have quite similar set ups, from some of your pictures I’d have said it was my grow tent. Same lights, intake fan and hung the same way. I saw on the first part of your journal you mentioned about it being first grow indoors, no restrictions. Just to confirm, not your first grow indoors? Struggling to think where I’d plant a grow in this miserable weather outside.
