Flowering time and yields

[PlainJane]

but still harvest is done by what Trichs look like ... correct?:icon506:

Yes. Their estimates are usually pretty close, from what I've heard, but it is just an estimate. I'm growing an "8 week" strain but 6 weeks into flowering and seeing all those clear trichomes, I think I may be in a while longer. You can, of course, harvest when you please but viewing the trichs for milky/amber gives you a better idea of when it is actually ready.
