If that worked for you, Great. Im personally ignorant about that technique so wont comment about that further.
but, they look almost done. A week or 2 maybe. Your pics not great but the reason I say that is the buds are a lil small and the hairs are still all white, also the leaves still look very green and healthy..... Get a cheapo 40x microscope and when the trichomes on the bud start to turn amber, youll be about there.
but defo... back under the lights.
