Your plants look awesome greenb. I wish I planted mine a little earlier (popped the soil on May 23rd). Mine are topping 15in atm. The thing that is annoying me is that if we ever have 2 consecutive day of great sunshine they explode, but the bloke on the weather programme won't let it happen often. Think it could be another shit summer, which will be a shame cause this is my only chance to grow at home for the next few years...
I'm no pro but it definately looks like some pre flowering going on in that party...
Remind me again... Did you buy feminized seeds?
Looking good, am very jealous
