How do I know when they're ready.

You can get technical and use a "Jewellers Loupe" to analyze the trichomes: I used to harvest when they are approx 50% amber ... but now I just  use my eye o meter =D

Looks to me like you could go another week or two then flush for a week ;-)

... Amber = Heavy stone, Clear-Cloudy = More Creative, Energetic type high

Thanks guys 

No probz =)

What strain?

Not sure to be honest anyone wanna have a guess?

Hehe looks alot like my last grow "Blue Cheese".

I am just about to transfer my new clones to grow room today, "Chocolate Kush" The mother is super healthy, grew really fast and bushy, also the clones rooted in under a week =)

BTW I wouldn't recommend Blue Cheese .... it was fairly mediocre ... nothing like Freeze Cheese 89!! hehe

I thinks its an ak47 

Ahh okay ... That would be classed as an "old school" strain now hehe. I have never grown it, but it is supposed to be a really hardy strain ... great for ScrOG =)
