Strain vs Hybrid, strains take years to develop and work out the different phenos to become stable. What we get from the suppliers are mostly Hybrids (not much better than bag seed), these will produce numbers of different looking, smelling, tasting plants. They can have different finish times as well. One of my hybrid lines showed 2 plants very indica, and another very sativa in looks. Unfortunately, the bugs liked the sativa one.
IF you can cover them for the rain tonight, my knee hurts, its coming this time, maybe not much, or move them inside. If not give them a gentle shake in the morning, dry air is coming.
