My first ever grow was WW in hydro and I remember it took about 9 weeks flowering.
Then I invited all my friends round to test the harvest and I destroyed everyone!

Your plants look wonderful and you don't have long to wait for a mind blowing smoke!!

How are the trichomes looking under the magnifying glass (if you have one. If not, you should get one)?
I didn't have one back then and just guessed by the colour of the pistols so the 9 weeks might not be correct but now I know better.

I currently have my 2nd ever Soil plants flowering and at 4.5 weeks they are a match for yours (bud size) so I'm very encouraged to see how yours look now!
