Trimming and Curing

Can you explain the relationship between trimming and curing in the cultivation of cannabis buds? How does one impact the other and what role does trimming play in the curing process?

Can LED lights be used for both veg and bloom stages?

I am considering purchasing LED lights for my cannabis plants, but I am not sure if they can be used for both the vegetative and blooming stages. Can LED lights be adjusted to accommodate both stages or is it necessary to have separate lights for each?
