@CGG, I see your plant is flowering nicely. I said last that planst will start to flower when light gets towards 12 hours - well that doesn't seem to be the case exactly. Currently Cape Town has about 13.5 hours theoretical day light (sun rise to sun set accordning to the weather bureau)... and I have plants that have just started to flower. A buddy of mine has one that almost looks ready for harvest - but his is on a side of a house where it only gets afternoon sun - thus it's effective daylight is kindoff cut short.
So you asked in your week 20 comments "not to sure how long she'll keep flowering for.", well the answer is not less that 8 weeks - I see you have 4 weeks logged on this diary as flowering - so you'll have to be patient for another month. You'll need to go back to exactly when she started to flower (not pre flowers). Google the strain - see if 7 to 9 weeks (usualy ave for Indica) Afgan Kush = Indica. Sativas flower longer .. say up to 14 weeks. Check youtube vids on when to harvest - they'll explain more than I can write here. Cool.
