postmandave- thats good to hear, not too long till flowering then. That sounds like a good plan with the lollipopping, I don't want to stunt them, but worse I don't want to stress them as a hermie could fuck up the whole thing.

Tomthehippie- thanks, I am a bit worried about heat. they're alright at the moment but as summer comes it's gunna get hot up there. I have an extraction fan (230m³hr, I don't know what that is in cfm) blowing hot air out and a tube sucking air in from outside. The hot air can disperse through vents in the roof all round the room. I also have a skylight which I can open to let in cool air to the attic. Last summer I didn't have a tube taking air in from outside so it got really hot up there and I got some hermies just before harvest (lucky). When I switch to 12/12 I'm gunna have the dark hours during the day and light at night. I'm hoping it doesn't get too hot. An attic is not a good place to grow but it's my only option, in winter it's too cold and summer too hot!

I'm going to update once a week so next pics are on the 21st
