@Jwjoh, ive got high hopes for the 8BK, the genetics look good and healthy. I just use the bottle tops as a cheap way to try and get more humidity to the younger plants that still want it higher than the others. I have taken that young alaskan purple out and put it in a new grow space with a bunch of other young plants and seedlings. They should be in a propogator really but i dont have one big enough.
